Apr 9, 2025 [Articles](https://microc.com/resources/articles) **|** Avoiding process headaches and operational downtime from making the wrong carbon source choice is critical for wastewater treatment plant operators whose time is in short supply. #### **The Choice is Clear** When it comes to choosing the right carbon source for biological nutrient removal (BNR), not all options are created equal, especially when it comes to making the best choice for glycerin-based carbon sources. In terms of glycerin-based carbon sources BNR plant operators generally have two main choices, EOSi’s MicroC® 2000 and crude glycerin. For reliability, peace of mind and overall cost-effective performance, the choice is clear - MicroC 2000 wins the day. #### **Manufacturing Quality Makes a Difference** EOSi’s MicroC® 2000 is a refined glycerin-based product, meaning that it has undergone manufacturing processes to remove excess levels of impurities such as salts, methanol, and other residues found in crude glycerin. While crude glycerin may seem like a “cheaper” solution in the short-term, MicroC offers unmatched advantages in product quality, supply chain reliability, and long-term cost savings. Unlike crude glycerin, which can vary in composition and availability, MicroC provides a consistent, higher-quality formula tailored to optimize biological nutrient removal and significantly eliminate quality related issues that lead to downtime. Crude glycerin is a “dirtier” form of the glycerol byproduct stream derived from biodiesel production. While crude glycerin may be a cheap carbon source, it typically is directly shipped from biodiesel manufacturers with no further processing and clean-up steps, which means it often contains unwanted impurities and contaminants grouped under the acronym MONG — material, organic, not-glycerin — fatty substances and solid material that cause problems with wastewater treatment pumps, tanks, handling equipment, and treatment processes. Avoiding clogged feed lines and pump system failures due to poor quality is the single most cited reason plant operators make the switch to MicroC 2000 which has little to no MONG content. | *Right: Crude glycerin samples tested by EOSi lab indicate a range in characteristics and quality.* Spotty quality control and chemical inconsistency of crude glycerin also wreaks havoc with optimizing carbon source feed rates within treatment systems with little tolerance for chemical variability. Guaranteeing product consistency is the primary reason why EOSi maintains in-house testing labs at every MicroC manufacturing location and is dedicated to frequent sampling and testing at every step of the production and delivery fulfillment process. EOSi’s extensive quality process ensures that plant operators get the same quality with every delivery. #### **Supply Chain Support Produces Better Outcomes** EOSi is dedicated to manufacturing MicroC® 2000 for BNR, supported by a robust supply chain network of over 20 sites across North America, reliable transportation and an operations team committed to ensuring tanks never run dry. Alternatively, crude glycerin is often supplied directly from a single source biodiesel manufacturer whose primary focus is fuel production, not wastewater treatment. Unlike EOSi, these suppliers do not specialize in BNR applications. As a result, if plant operations are disrupted or additional support is required, the necessary expertise is not available to ensure things go right. #### **MicroC® 2000 Advantage: Expert Insight & Automation** MicroC® is backed by EOSi’s expert in-house technical support and cutting-edge Nitrack® automation which helps wastewater treatment facilities streamline operations, reduce feed rate costs, and enhance system performance—ensuring efficiency and compliance without the risks of variability. Most operators express the real differentiating value between crude glycerin and MicroC is the expertise, experience, and immediate availability of EOSi’s process engineers dedicated to helping customers use MicroC most cost-effectively. Additionally, EOSi’s Nitrack automated dosing control system helps boost efficiencies and reduce MicroC feed costs by up to 30% by analyzing fluctuations in influent loading, accurately predicting the precise chemical dosing, and minimizing unnecessary dosing by dynamically optimizing the feed rate. EOSi is the only company on the market that provides the combination of non-hazardous glycerin-based carbon sources, a proven automation control system that optimizes the feed rate, and the engineering support to back it up year-round. Facilities who initially favored crude glycerin due to lower cost discovered that poor quality crude glycerin did not permit their biological nutrient removal process to operate properly and they often switched back to MicroC in as little as three months and never switched again.

Feb 18, 2021 [News & Press](https://microc.com/resources/news) *Global Water Intelligence By Ian Elkins* The water quality solutions platform created in 2019 by KKR and XPV Water Partners was rebranded this month as Axius Water, simultaneous with the appointment of seasoned water veterans Gretchen McClain and Debra Coy as independent board members. The move reunites McClain with Axius CEO Chris McIntire, who founded Nova Analytics before running Xylem’s analytics and treatment businesses under McClain after she took over as group CEO in 2011. “We felt that having industry experts with deep connections to how things happen on the ground in water would be a welcome addition to the board room,” McIntire told GWI this month. “As we thought about adding some independent board members, Gretchen and Debra were right at the top of the list, and we were fortunate to be able to get both of them enthusiastic about what we’re doing.” There is understood to be no conflict between McClain’s role as an operating executive at The Carlyle Group and her board position at KKR-backed Axius Water. # Axius Water’s Branded Water Offering The three businesses that sit under Axius Water will retain the branding on which they have built their reputations. More acquisitions will follow as the group broadens its international reach. ## Fixing the Plumbing Since joining Axius in July 2020 – shortly after the acquisition of EDI – McIntire has been focused on getting what he calls the “financial plumbing” of the business right, recruiting a new CFO, and preparing for the next wave of M&A activity. His track record of rolling up fragmented markets (first at Nova Analytics, and then at food instrumentation company KPM Analytics) gives him a natural advantage, and he is keen to expand the international reach of the Axius platform. “We have a pretty robust pipeline of companies that we’re talking to,” he told us. “Today we are a largely North American business. In terms of where I see us going, I expect we will add businesses that have their centre of operations in Western Europe and North America. My experience has been that North American businesses can struggle to project appropriate technologies to Europe, and European companies can likewise struggle to bring technology to North America. Adding companies in Europe to our group will give us that customer intimacy much more quickly. “We want to build a meaningful group of companies that make sense together in terms of products and geographies. I think about our commercial organisation as a ‘hand’, but when it comes down to it, the ‘fingers’ have to touch the customers. As we look at acquisitions, some of them will make the ‘hand’ a little bigger, and some of them may add another ‘finger’.” McIntire is unfazed by the suggestion that there are bigger competitors out there with bigger balance sheets to put to work. “The individuals in our businesses know how to apply technologies in a way that solves customers’ problems better than the next competitor. Our basis of competition really comes down to application and domain expertise, and that ability is not directly tied to scale,” he explained. “Our companies have built their reputations on solving customers’ problems, and those reputations are embodied in their brands.” ## Getting Ahead of the Regs Much of the business conducted by Axius Water’s three portfolio companies is predicated on addressing the regulatory requirements of municipal customers, and for them to remain competitive, they have to stay one step ahead of nutrient legislation. “Businesses like Nexom, EDI and EOSi all have solutions that can make existing facilities and footprints more effective, particularly when it comes to hitting regulations and discharge requirements. The reality is that nutrients are regulated in a very local way, so staying close to the market and understanding where the regulations are coming from is a key competency of the business,” said McIntire. “We’re in a good position to get this right and to make sure that we’re able to maximize our acquisitions in a way that we keep those talents alive. I feel like we really have a lot of the right ingredients in place to be able to succeed.” --- # How the Right BNR Carbon Source Supports Net Zero Emission Targets Jul 2, 2025 [Articles](https://microc.com/resources/articles) **Net Zero Emissions for Wastewater Treatment** Today’s wastewater treatment industry is actively adapting treatment processes to counter global warming and climate change, and plant operators are striving to reduce their facility’s contributions to rising levels of greenhouse gases (GHG) in the Earth’s atmosphere that trap and preventing heat from escaping back to space. Plant operators are now moving beyond earlier “carbon neutral” strategies criticized for their heavy reliance on limited-scope reduction targets and the purchasing of carbon-credit offsets seen as “greenwashing.” Net Zero is the newer and far more ambitious and comprehensive industry target. Net Zero still requires offsetting GHG emissions, but is more focused on greatly reducing direct Scope 1 emissions, indirect Scope 2 emissions, and difficult-to-quantify Scope 3 emissions. What does this mean for treatment-plant operators? For plants using supplemental carbon for biological nutrient removal, it means migrating to biogenic carbon sources that significantly minimize plant-controlled direct and indirect Scope 1/Scope 2 GHG emissions, and collaborating to reduce Scope 3 GHG emissions that do not result directly from wastewater-treatment (such as supply-chain activities). **MicroC® vs Methanol** Carbon dioxide emissions from supplemental carbon use for biological nutrient removal can make up as much as 80% of a wastewater treatment plant’s Scope 1 GHG emissions, and may even be responsible for up to 30% of a facility’s combined Scope 1 and Scope 2 emissions, potentially second only to purchased electrical power. Methanol, still used as a carbon source by older treatment plants, can potentially hike those Scope 1 and 2 GHG emissions to unacceptable levels for Net Zero targets. In contrast, using biogenic carbon sources like EOSi’s MicroC® can potentially reduce or eliminate these Scope 1 and 2 GHG emissions. Potential trade-offs: some biogenic carbon sources will have higher yields than many of the typical fossil fuel-derived carbon sources, leading to increased solids production that may either offset or enhance the reduced Scope 1 and 2 emissions with changes to Scope 3 emissions. These outcomes depend heavily on the solids-handling methods of a given treatment facility. EOSi recently conducted research focused on the global-warming potential of the two most widely used carbon sources for nutrient removal across North America: EOSi’s MicroC and methanol. The study compared different carbon sources in terms of CO2 equivalent emissions per unit of NO3 removal, and analyzed the impacts of variable dosing rates, solids generation and handling, and sensitivity to methods of solids handling employed. **Carbon Source Matters – MicroC**® **Means Lower Emissions** Analysis performed around six hypothetical treatment plant scenarios calculated carbon source dosing rates, biogenic and non-biogenic emissions associated with the carbon sources from the secondary process, and incremental observed-solids generation. Included were emissions from production of the carbon source, utilization of the carbon source in the anoxic zone, digestion of the incremental sludge generated upon utilization of the carbon source, generation of electricity and heat from the biogas produced (in some scenarios), transport and land application, landfill, or incineration of residual sludge. The life-cycle results for the six scenarios analyzed revealed the cradle-to-grave emissions per unit of NOx removed with the MicroC® carbon sources *were between 52% and 98% lower than those of methanol*. The study also found that utilization of MicroC biogenic carbon sources reduced supplemental carbon source-related Scope 1 emissions for the wastewater treatment facility by a higher margin: *nearly 100% in the scenarios analyzed*, unless incinerated onsite. Biogenic carbon sources like MicroC can demonstrably offer overall greenhouse gas reduction to wastewater treatment facilities under a variety of solids-handling scenarios. Despite potentially generating larger quantities of solids, relatively large anthropogenic Scope 1 GHG savings and possible Scope 2 savings for plants using combined heat and power units more than offset the additional emissions from the incremental solids generated. Further, MicroC supplemental carbon may help reduce overall plant emissions by enhancing denitrification COD/N and thereby reducing anoxic N2O emissions, enabling plants to simultaneously achieve cost-effective nutrient removal, GHG reduction, and Net Zero targets. #### [\[Download/View Article PDF\]](https://microc.com/uploaded/pdfs/How-the-Right-BNR-Carbon-Source-Supports-Net-Zero-Emission-Targets-06.25.pdf) --- # Safeguarding Cybersecurity with EOSi’s Virtual Nitrack®: Ultra-secure Biological Nutrient Removal Optimization with Cloud-based Process Automation Sep 24, 2025 [Articles](https://microc.com/resources/articles) **Virtual Nitrack® Cloud-based MicroC® Optimization** EOSi’s Virtual Nitrack software-based system frees wastewater treatment plant operators from the high cost and technology constraints of older hardware-based biological nutrient removal optimization systems and adds advanced multilayered security, access control, encryption, and other safeguards to deter the increasing threats of hacking and cyberattacks. Like EOSi’s hardware-based predecessors, the Virtual Nitrack system enables automating, monitoring, and optimizing biological nutrient removal dosing of MicroC supplemental carbon sources widely used in denitrification, enhanced biological phosphorus removal (EBPR), and biochemical oxygen demand (BOD) addition applications. In contrast, the Virtual Nitrack software exists and operates “in the cloud,” migrating processes and processing formerly handled by onsite computer hardware to a “virtualized” cloud-computing environment that enables plant operators to achieve consistent permit compliance with a new lower-cost, rapidly deployable, and ultra-secure solution. **Powerful Enterprise-Grade System Security** The Virtual Nitrack system was designed from the ground-up to deliver powerful enterprise-grade security. End-to-end TLS/SSL encryption (TLS (Transport Layer Security) and SSL (Secure Sockets Layer) ensures application access and all communications from local nodes to the cloud is secure and encrypted to deny unauthorized access, data monitoring, or configuration changes. All sensors and devices communicating with the Nitrack system are secured with authentication and access control. IIoT (Industrial internet of things) gateway and cellular probes feed data to the cloud through encrypted channels, safeguarded by stateful firewalls and certified security protocols. Supporting the Virtual Nitrack system are several enterprise-grade technologies maintained with up-to-date firewalls, full cybersecurity implementations, and full daily backups stored offline, including Microsoft’s Azure cloud-computing platform, Microsoft SQL Server database management, a specialized data broker service for monitoring business-critical data traffic, and Inductive Automation’s Ignition industrial application platform using Cirrus Link’s MQTT Engine encrypted data pathways. In the field, SignalFire cellular transmitters deliver process data values to Moxa industrial networking and communications units installed onsite at the treatment plant, providing secure “pull and push” data communications between the plant’s PLC network and the Virtual Nitrack system. Firewalls allow VPN-only (virtual private network) access to Moxa devices, and physically separate “air gapped” networking connectivity ensures no active connections exist between the subnet used for the PLCs, the cellular network, or the network subnet used internally by Cirrus Link’s MQTT gateways. Further, the MQTT protocol defeats data interception or hacking by transmitting only tiny amounts of non-contextual numerical data on a third cellular connection also encrypted and linked to secure CA digital certificates. **System Monitoring and Operational Security** The Virtual Nitrack system also offers built-in operational safeguards, including active system monitoring, change logs, notifications, alerts, and optional layers of automated security. If a Virtual Nitrack system starts performing abnormally because of user error, system misconfiguration, or even an unauthorized “bad actor,” EOSi’s active monitoring enables reacting quickly and decisively within minutes of detection. Virtual Nitrack logs all actions of any user who uses the system, monitoring remotely and recording what they are doing, all actions taken, or any changes made to the system settings. If a user activates or stops a particular pump, Virtual Nitrack creates a log entry revealing who did it, what time they did it, and what action was performed. System administrators can review any changes or modifications to the system, and either remedy the situation or establish safeguards to prevent a reoccurrence. Login “timeouts” are an example of automated security measures to prevent unauthorized persons from accessing and making changes to Virtual Nitrack system programming values using unattended plant workstations still actively logged into the application. Other automated security measures include intelligent safeguards preventing excessive or nonstandard system values from being entered into the software, automatic notifications or alerts if the system detects improper levels of MicroC are being applied for wastewater treatment, automatic user lockouts to prevent certain system values from being configured, and more. EOSi is evaluating using AI functionality limited to assisting plant operators and users achieve more efficient operation with their Virtual Nitrack-driven nutrient removal system, including AI tools programmed to provide training assistance or system status updates. But future iterations will focus on incorporating operational improvements and strengthened safeguards to ensure a more reliable, available, and ultra-secure Virtual Nitrack system that enables plant operators to comply quickly with new wastewater treatment regulations or permit restrictions.

Many states are moving toward stricter discharge limits and advanced treatment requirements, a primary force reshaping wastewater operations over the next two years. [Recent analyses](https://www.epa.gov/system/files/documents/2024-07/fy-2025-2026-ow-npg.pdf) highlight intensified efforts in California and throughout the Mississippi River Basin, alongside evolving expectations for utilities nationwide signaling that 2026 will be a pivotal horizon for TN/TP performance and enforceability. In Florida, [legislative updates](https://assets.noviams.com/novi-file-uploads/frwa/FocusOnChange/2025WastewaterUpdate.pdf) push Advanced Wastewater Treatment (AWT) standards and expanded reuse planning, with agencies emphasizing programmatic changes and permitting implications now working through district offices. For facilities discharging to sensitive waters like springs, lagoons and estuaries stricter nutrient outcomes and reuse feasibility requirements are accelerating timelines and investments. **The Regulatory Landscape: What’s Changing** - *State & watershed initiatives:* California, Chesapeake Bay, Great Lakes, and Gulf-bound watersheds are tightening TN/TP limits to curb algal blooms. EPA and state reports point to accelerated nutrient strategies, with compliance deadlines varying by region but generally leading towards mid-decade. - *Mississippi River Basin focus:* Utilities feeding the Basin are under increased scrutiny to help reduce hypoxia in the Gulf of Mexico, affecting more than 1,200 publicly owned treatment facilities as programs standardize monitoring and nutrient removal expectations. - *Florida AWT & reuse:* Florida’s recent legislation expands AWT expectations and reuse feasibility studies, pushing facilities to meet stricter TN/TP standards and pursue reclaimed water programs, reshaping both municipal and industrial operations. *Implication:* Permit risk is rising. Plants that rely on variable influent carbon or manual dosing face greater odds of excursions. [Supplemental carbon](microc.com/products) and [automation](https://microc.com/what-is-nitrack) are fast becoming the practical path to consistent and affordable compliance. **Why Supplemental Carbon Is Central to 2026 Compliance** Most facilities targeting tight TN limits rely on biological denitrification, which occurs after aerobic bacteria converts ammonia to nitrate in a nitrification process under anoxic conditions. When native carbon is insufficient or inconsistent, a high-quality supplemental carbon source is added to convert nitrate to nitrogen gas, stabilize BNR kinetics and protect effluent performance. EOSi’s MicroC® Premium Carbon Sources are engineered for BNR applications delivering consistent quality, industry validation (550+ plants), and a variety of options for different process needs (carbohydrate-based, glycerin-based, alcohol-based, and custom formulations). Choosing MicroC helps plants [achieve TN/TP targets](https://microc.com/nitrogen) with safer handling and predictable dosing compared to alternatives. **Enhancing MicroC® with Nitrack®: Precision Dosing for Risk Reduction** As limits tighten, the margin for error shrinks. EOSi’s Nitrack® integrates feed-forward (process kinetics) and feedback (hydraulics, sensor inputs) control to deliver a fully automated nutrient removal program avoiding overdosing and underfeeding, and stabilizing effluent. Facilities benefit from remote monitoring, alarms, and performance reporting, aligning operations with permit constraints while containing chemical costs. For plants needing rapid deployment or reduced on-site hardware, [Virtual Nitrack](https://microc.com/resources/articles/virtual-nitrack-article) enables cloud-based control with strong cybersecurity, cellular connectivity to probes and pumps, and 20%+ MicroC savings, tightening process control without lengthy installs or capital-intensive retrofits. **What Facilities in Key Regions Should Do Now** - Florida & Southeast U.S.: Evaluate AWT impacts and reuse feasibility; confirm EBPR readiness and denitrification capacity under seasonal temperature swings. Consider MicroC + Virtual Nitrack to accelerate control, minimize onsite changes, and support goals. - California & West Coast: Prepare for stricter TN/TP proposals and energy pressures; explore low-DO BNR with responsive carbon dosing to balance compliance and OPEX. - Chesapeake Bay, Great Lakes, Mississippi River Basin: Expect increased accountability in TN/TP outcomes; use MicroC to stabilize denitrification and EBPR, and automation to reduce risk as regional programs intensify. *A Practical 2026 Compliance Checklist* 1. Benchmark performance: Compare current TN/TP medians and 95th percentile values against expected permit tightening. 2. Carbon sufficiency test: Conduct bench/pilot evaluations to confirm readily supplemental carbon needs across seasons. 3. Dosing strategy: Implement [Nitrack automated control program](https://microc.com/what-is-nitrack); set effluent setpoints and alarms tied to permit thresholds. 4. Supply assurance: Choose MicroC for consistent quality, validated by [EOSi’s lab-driven QA](https://microc.com/resources/articles/eosi-lab-article) across manufacturing locations. 5.

These incidents included fires, explosions, leaks, and releases involving toxic and flammable substances, many of which resulted in injuries, fatalities, evacuations, and environmental damage. While these events span multiple industries, they share a common theme: chemical risk is pervasive wherever hazardous materials are stored, transported, or used operationally. Wastewater treatment is often viewed as lower risk than petrochemical or manufacturing sectors, but even essential public infrastructure is not immune to chemical hazards Within the same dataset, 13 hazardous chemical incidents occurred specifically in water and wastewater treatment facilities. In many cases, these facilities rely on external carbon sources like methanol to support biological nutrient removal (BNR). While effective, methanol introduces a set of safety and operational risks that deserve closer attention. **Methanol in BNR: Effective but Not Without Risk** Methanol has long been used as a supplemental carbon source to drive denitrification processes. However, its classification and behavior introduce inherent challenges: - Highly flammable: Methanol presents fire and explosion risks during storage, transport, and handling. - Toxic exposure risk: Inhalation, ingestion, or skin contact can cause serious health effects. - Logistical complexity: Bulk storage and delivery increase site risk and regulatory oversight requirements. These characteristics mirror many of the same risk factors seen across the broader chemical incident dataset, particularly where flammable liquids and volatile organics are involved in fires, explosions, and releases. This confirms carbon source selection is not just a process decision, it is also a safety decision. **A Shift Toward Safer Carbon Alternatives** As utilities evaluate ways to improve resilience and reduce operational risk, many are reconsidering traditional inputs like methanol. Safer alternatives like EOSi’s MicroC® focus on maintaining performance in denitrification while reducing hazards associated with storage and handling. MicroC®, and specifically MicroC® 2000 refined-glycerin carbon sources, were developed to provide: - Readily biodegradable carbon to support efficient denitrification - Reduced hazard profile compared to highly flammable carbon sources like methanol - Operational stability, with consistent quality and predictable performance As the wastewater sector faces increasing pressure to meet nutrient limits while ensuring worker and community safety. Solutions like MicroC® help utilities reduce exposure and meet regulatory goals without compromising treatment outcomes. ##### | Coming Clean inc.

EOSi engineers designed Virtual Nitrack to operate with a minimal site footprint with low impact to ongoing operations, to be quickly deployable for both pilot projects and long-term installation, and easily accessible by both remote and local plant staff via EOSi’s user-friendly optimization management application for configuring, monitoring, and controlling supplemental carbon dosing in the wastewater treatment process. The Nitrack can even be deployed using cellular transmitters on probes, flowmeters, and feed pumps, allowing for functionality without running signal wires across the plant. “Virtual Nitrack can be set up and running within hours,” says EOSi control and instrumentation engineer David Fournier. “Deploying a cloud-based control system like Virtual Nitrack avoids spending weeks onsite at a plant installing everything necessary for a traditional hardware-based control system. Our cloud-based system also enables remote monitoring, system control, quick-response support — even the capability of remotely accessing and tweaking system code at the utility’s request in response to rapidly changing operational situations and unanticipated events.” EOSi’s advanced, rapid, and customizable Virtual Nitrack technology has allowed for its engineers to pioneer new ways to automate both temporary and permanent installations at little to no cost to the customer while typically saving over 20% to their MicroC cost. Stress-Free Optimization Access** “Our Virtual Nitrack application enables configuring, monitoring, tracking, and controlling all aspects of the system both locally or remotely, and includes a wide selection of data views ranging from real-time operational system parameters and process values to historical data for analyzing system performance,” says EOSi’s Fournier. “We focused on maximum useability for plant staff, enabling the app to accommodate an array of mobile devices with varying screen resolutions, so all application screens and data views are completely accessible and useable in the field using a phone or a tablet, or at a dedicated workstation.” The app greets users with a control system dashboard overview highlighting the most critical system parameters and process values. Tank inventory and consumption data include a user-configurable low-inventory alarm. Pump overviews display pump status and enables users to start and stop pump dosing. Performance upsets or failures are highlighted with red indicators or yellow if the status is unknown, and detailed alarms assist with troubleshooting or maintenance, enabling operators to place the pump in manual mode during sensor maintenance. Denitrification efficiency, or the amount of MicroC used per lb of nitrogen removed, is tracked and trended over time so that operators can verify ongoing optimum performance. The app’s Anoxic Basin screen displays system parameters as a process overview, highlighting control system inputs, outputs, and the set point used for optimizing feeds for chemical dosing pumps. Configurable pump properties enable operators to control and set minimum and maximum pump speed rates, working seamlessly with EOSi’s integrated pump skids that feature a special factory calibration compensation value or “calibration comp” for precisely fine-tuning the pump and optimizing the feed. “The app enables plant staff, EOSi engineers, and the EOSi automation team to leverage Virtual Nitrack’s real-time continuous monitoring of everything happening in your wastewater treatment process,” says EOSi’s Pulsifer. “That’s the key part: the EOSi engineering team is always monitoring treatment system data and continually advising utilities on optimizing the process — which is probably the biggest benefit for our wastewater treatment customers.” **Industry-Recognized Innovation** EOSi’s Virtual Nitrack was recently selected in 2024 as a finalist in Inductive Automation’s annual [Ignition Firebrand Awards](https://microc.com/resources/awards/icc24-award), a prestigious cloud-computing industry award honoring system integrators and industrial organizations creating exceptionally innovative and successful projects that leverage Inductive Automation’s Ignition cloud-software platform — with Virtual Nitrack being the only Firebrand Award finalist innovating a cloud-based control system for the wastewater processing industry. Other water-industry solutions offered by EOSi’s sister companies within the Axius Water family of companies are actively leveraging EOSi’s proprietary process automation technologies and algorithms, notably EDI’s Digital Dynamic Wet Pressure monitoring system (DDWP) for monitoring the operational status of diffuser membranes used in wastewater treatment aeration systems. “Today, more than 20 wastewater treatment plants across North America are successfully operating their biological nutrient removal programs using Virtual Nitrack,” says EOSi sales and marketing VP Jeffrey Prellberg. “EOSi is only company on the market that provides the combination of non-hazardous glycerin-based carbon supplements, a proven automation control system that optimizes the feed rate, and the engineering support to back it up year-round.

[Learn More](https://microc.com/weftec) --- # MicroC® Supports Biomass During Startup, Shutdown and Variable Loadings [Case Studies](https://microc.com/resources/case-studies) The effectiveness of biological wastewater treatment depends on having a healthy, sufficient biomass. Supplementing the biochemical oxygen demand (BOD) of the influent wastewater with a carbon source such as MicroC® Premium Carbon Sources can help establish or sustain the biomass during periods of low BOD loading. This is an additional application for Environmental Operating Solutions, Inc.’s (EOSi’s) products, which are well-known for denitrification. BOD Supplementation, also referred to as BOD Augmentation and BOD Addition, is the practice of adding organic compounds to wastewater as needed to establish or sustain a healthy, adequate biomass in the treatment system. The extra carbon and energy promote bacterial growth and reproduction. --- # Denver-Area WWTP Migrates from Methanol to EOSi’s MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) A central Colorado wastewater treatment facility concerned with their continued use of methanol as a supplementary carbon source embarked on a test program to investigate using non-hazardous and less costly alternatives. In addition to methanol’s inherent safety and toxicity risks and unstable price-fluctuation issues, using methanol as a supplementary carbon source also typically involves expensive infrastructure and equipment investment, strict regulatory requirements, significant environmental impact, unique bioengineering challenges, lower carbon efficiency, and more. Research indicated many previous attempts to use non-methanol carbon sources in down flow denitrification filters similar to that used at the Colorado facility failed to consider the down flow filter operation itself may require modification because of differences in yield and kinetic characteristics of alternative carbon sources relative to methanol. --- # EOSi’s Nitrack® Carbon Source Automation Make Florida County WWTPs Low-Nitrogen Compliant [Case Studies](https://microc.com/resources/case-studies) The Florida county operates three municipal wastewater treatment facilities, with its West WWTP facility processing an average flow of 2.4 MGD through a 5-stage Bardenpho process, and its Central WWTP processing an average flow of 2.3 MGD through Veolia’s proprietary Biodenipho™ biological wastewater treatment (essentially utilizing the principles of a standard 4-stage Bardenpho process for removing carbon, nitrogen, and phosphorus). The Florida county’s Central WWTP had an existing Total Nitrogen (TN) effluent limit of 12 mg/L but was faced with a future TN effluent permit limit of only 3mg./L. The county commissioned an evaluation of EOSi’s Nitrack® Program for delivering optimized dosing of EOSi MicroC® 2000 carbon sources. Would the EOSi solution enable the Central WWTP to consistently meet the future effluent TN target of 3mg./L or below — even with the high variability in NOx loading to the secondary anoxic further complicating the situation? --- # FL WWTP Meets Future Permit using EOSi’S Nitrack® Carbon Source Automation [Case Studies](https://microc.com/resources/case-studies) A Florida municipal water reclamation plant operating with a daily average flow of 3.4 MGD through a 4-stage Bardenpho Process configuration was meeting their current TN (total nitrogen) permit readily and consistently, but the facility was struggling with meeting the AWT (Association of Water Technologies) requirements and reducing the average annual TN effluent concentration to 3 mg/L or below. Receiving leachate sporadically and without warning throughout the year, the plant’s lack of leachate flow equalization or pretreatment made the plant’s incoming TN load difficult to predict and accommodate and caused many process upsets. Seeking a solution that would solve both their present and future permit challenges, the facility conducted a two-week evaluation using manually applied doses of carbon to determine if meeting future effluent goals was possible —without resorting to a full plant upgrade. --- # Enhanced Safety & BNR: FL WWTP Migrates from Methanol to Non-Hazardous MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) The Florida municipal wastewater treatment plant using methanol for many years as the supplemental carbon source needed to support denitrification for biological nitrogen removal(BNR) was faced with upgrading their aging methanol facility and equipment. Methanol’s inherent safety and toxicity risks typically involve expensive capital infrastructure and equipment, and strict regulatory requirements regarding storage, handling, and minimizing environmental impact. Faced with safety risk, high upgrade cost, and low efficiency of continuing with methanol as a carbon source, treatment plant operators chose instead to switch to a safer, non-flammable supplemental carbon source: EOSi’s MicroC®2000. Supporting both denitrification and biological phosphorus removal, non-hazardous MicroC 2000 eliminates flammability and toxicity concerns of using methanol, delivers substantial capital cost savings over flammable liquid storage and feed systems, and enables rapid and flexible deployment of advanced carbon augmentation solutions. --- # HRSD Intensifies Dentrification, Securing Savings & Compliance with Bio-Based MicroC® 3000 [Case Studies](https://microc.com/resources/case-studies) Providing wastewater treatment services to more than 1.6 million people in southeastern Virginia, the Hampton Roads Sanitation District(HRSD) operates nine major plants in the Hampton Roads area and four smaller plants in the Middle Peninsula area. HRSD’s Nansemond Treatment Plant is among HRSD’s larger plants. With an average daily flow design of 30 MGD, the Nansemond plant utilizes a 5-stageBardenpho® process to meet biological nutrient removal (BNR) standards of approximately 8 mg/L of total nitrogen (TN)and 1 mg/L of total phosphorus (TP). The Nansemond plant had previously used glycerin-based carbon sources for wastewater treatment denitrification. But the plant’s newly installed storage and feed system for dispensing external carbon sources enabled them to flexibly use several different types of carbon sources including methanol. --- # Midwest WWTP Overloaded by Industrial Influent Rescued from Permit Probation by EOSi’s MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) A small midwestern USA municipality owning and operating a 1.5 MGD wastewater treatment plant (WWTP) was treating both municipal and industrial wastewater, including substantial inflow from a local pork-processing facility. The municipality’s WWTP uses oxidation-ditch technology — circular or oval-shaped aeration-activated sludge basins — to achieve biochemical/biological oxygen demand(BOD) removal, nitrification, and denitrification. An evaluation of the WWTP’s influent wastewater characteristics highlighted a significant shortfall in the BOD loading compared to its ammonia loading. The high ammonia levels in the influent resulted from the WWTP receiving more than 50% of its inflow from a local pork-processing industrial discharger. The WWTP was required to meet strict weekly and monthly average ammonia and pH effluent limits but was frequently exceeding those limits — and endangering their operating permit. --- # Transforming EBPR: Non-VFA Pathway Success With EOSi’s MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) The Maryland 7.5 MGD treatment plant operates four trains, each consisting of nine reactors. The mixed liquor suspended solids (MLSS) from the four trains flow into a common post anoxic zone(ML1 to ML3) prior to membrane bioreactor (MBR)basins. Recirculating aquaculture systems (RAS) deliver MBR discharges to Reactor #5A of each train. The process can recirculate the MLSS from Reactor #8to Reactor #1 (a four-stage configuration) or from Reactor #8 to Reactor #3 (a five-stage configuration). The plant is required to comply with a total phosphorus (TP) discharge limit of 6,820 lbs. per year, corresponding to concentrations of 0.3 mg P/L. The plant is also required to meet a total nitrogen (TN) discharge limit of 4.1 mg N/L, accomplished historically by adding methanol at average rates of 260 and 300 gallons per day (GPD)and to the primary effluent and post anoxic zones respectively, totaling 560-650 GPD of methanol. --- # Midwest Reclamation EBPR Evaluation: Assessing MicroC® 2000 For Ample Phosphorus Reduction [Case Studies](https://microc.com/resources/case-studies) The 354 MGD water reclamation facility serving 1.1 million people within an area of 300 square miles had converted two of the plant’s five wastewater-treatment batteries to an anoxic-anaerobic-oxic (A2O) configuration to improve the plant’s phosphorus-removal performance. However, preliminary testing conducted by the facility’s maintenance, operations, engineering and research teams determined that the plant’s activated-sludge process readings of BOD:P of 15 (biochemical oxygen demand-phosphorus ratio) indicated a significant carbon deficiency to sustain the proper microorganisms necessary for waste reduction. Two of the plant’s five batteries (A Battery and B Battery) were reconfigured to provide a suitable environment for enhanced biological phosphorus removal (EBPR). The two batteries were converted to an anoxic-anaerobic-oxic (A2O) configuration by modifying the diffused air flow along the 415-foot length of each of the eleven trains within each battery. --- # NC Reclamation Facility Boosts Denitrification & Compliance While Reducing MicroC® 2000 Cost [Case Studies](https://microc.com/resources/case-studies) The North Carolina water reclamation facility is designed for a maximum flow of 3.6 MGD, consisting of one anoxic ditch and two oxidation ditches configured as an MLE — a Modified Ludzack-Ettinger process using nitrate produced in the aeration zone as a source of oxygen for treatment bacteria needed in the event of the breakdown of raw wastewater in the anoxic pan. Historically, the plant treated approximately 3.5MGD of municipal wastewater and discharged the treated effluent to a surface waterway, with a TN(total nitrogen) limit of 40,457 lbs./year, corresponding to 4.0 mg N/L at full design flow. The plant has been using EOSi’s MicroC® 2000 as a supplemental carbon source for several years, with RAS (return activated sludge) and nitrate recirculation flows averaging 3.5 MGD and 35-42MGD, respectively. --- # Pennsylvania Beef-Processor Conquers BNR Obstacles & Compliance With EOSi’s MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) An Eastern Pennsylvania Industrial beef-processing plant seeking to comply with their total maximum daily load (TMDL) permit limits upgraded their onsite wastewater treatment plant(WWTP) from a conventional activated-sludge plant to a dual-train, four-stage Bardenpho activated-sludge process. Prior to the plant’s biological nutrient removal(BNR) upgrade, it historically discharged greater than 200 mg/L total nitrogen (TN). However, the plant’s new National Pollutant Discharge Elimination System (NPDES) permit required an annual TN average concentration of less than 8mg/l and a daily maximum TN of 130 mg/l at a flowrate of 0.5 MGD. With very high nitrogen loading with peaks of up to 300 mg/l TN and low carbon/nitrogen ratios in the anoxic zones, the plant design required using supplemental carbon to facilitate denitrification to comply with the NPDES permit limits. Citing safety, low cost, and high quality, EOSi’s MicroC® 2000was chosen as the supplemental carbon source for the wastewater treatment facility. --- # Molasses to MicroC: PA Coal-Fired Power Generation Station Meets Nitrate & Selenium Reduction Goals with MicroC® 4100 [Case Studies](https://microc.com/resources/case-studies) In 2013, the US Environmental Protection Agency(EPA) released proposed Effluent Limitation Guidelines (ELGs) for the category regulating steam-electric power generating point sources. The proposed ELG rule will require specific treatment of wastewater from flue gas desulfurization (FGD) processes, with treatment goals identified for selenium, nitrate and nitrite, arsenic, and mercury. The diverse chemistry of these contaminants combined with the very low concentrations in the proposed standard present a formidable challenge for the power industry to achieve. Discharge permits have been issued for some FGD wastewater treatment facilities. Selenium, mercury, chlorides, total dissolved solids (TDS), organics, and other trace metals are typically the parameters of interest in the most recent National Pollutant Discharge Eliminating System (NPDES) permits regulating FGD wastewater. --- # Process Control Improvements for Industrial Denitrification [Case Studies](https://microc.com/resources/case-studies) The industrial protein and rendering facility located near Virginia’s eastern shore typically handles more than 1 MGD flow highly concentrated with nitrogen. Like many industrial plants that pause treatment operations on weekends, irregular plant-loading variability combined with high loading and low nutrient limits create carbon-dosing process control challenges with little margin for error. In this case, even resorting to a manual-dosing strategy to compensate for the variabilities often resulted in both early-week carbon underdosing and late-week carbon overdosing — creating havoc with denitrification levels and putting the plant’s permit compliance at risk. Carbon-source supplementation in wastewater treatment directly impacts the denitrification process, so accurate dosing of carbon sources is vital for improving the quality of effluent from wastewater treatment. Adhering consistently to a well-chosen carbon-source dosing setpoint typically ensures the most efficient operation and lowest cost needed to meet wastewater-quality targets. --- # Methanol to MicroC: Washington WWTP Reduces Cost & Risk with Non-hazardous EOSi MicroC® 2000 [Case Studies](https://microc.com/resources/case-studies) The Washington municipal wastewater treatment plant (WWTP) operating with a daily average flow of 10.75 MGD through a 4-stage Bardenpho configuration was meeting its seasonal TN permit requirements consistently using methanol as a supplemental carbon source. The facility dosed methanol year-round using a feed-forward automation control to maintain the necessary population of methylotrophic bacteria required for denitrification during their critical 7-month permit season. The facility was considering upgrading their existing methanol storage and feed system but also evaluating potentially safer, cheaper, more efficient, and more environmentally sustainable alternatives to using methanol as a supplementary carbon source. Highly flammable and toxic, methanol as a supplemental carbon source poses storage and handling safety risks to personnel and the surrounding environment, and involves strict safety protocols, careful monitoring and dosage controls, and costly regulatory compliance challenges. Given the overall high expense of storage and feed systems for flammable and toxic chemicals, the facility was facing a large capital investment if they continued with methanol... --- # South Florida WRF Evaluates & Switches from Methanol to Nonhazardous MicroC® 2000 for Enhanced Filter Denitrification [Case Studies](https://microc.com/resources/case-studies) The South Florida municipal water reclamation facility (WRF) operating with a daily average flow of 3 MGD was using methanol for supplemental carbon dosing to comply with the facility’s effluent permit requirements of 3 mg/L total nitrogen (TN). The facility dispensed methanol using a flow-paced automation strategy involving Tetra denitrification filtration, a process using shallowbed micro-media filtering with added carbon sources to metabolize nitrates in wastewater effluent into subsequently released nitrogen gas. The facility wanted to eliminate the inherent safety risks and costly transport, handling, and storage costs requirements for using hazardous materials like methanol, and identified EOSi’s non-hazardous and non-flammable MicroC 2000 as a potential carbon source replacement for denitrification. But would using MicroC 2000 be operationally viable in a Tetra denitrification filtration process designed for methanol use? --- # Texas Beef-Processor Meets Stringent TN Limits Using MicroC® 2000 and Nitrack® Automation [Case Studies](https://microc.com/resources/case-studies) The Texas beef-processing plant’s wastewater treatment facility operates two anaerobic lagoons discharging into two controlled swing-zone lagoons, each with eighteen aeration zones. Like many protein-processing plants, this facility produces wastewater with highly variable flowrates and contaminant concentrations. Influent to the wastewater treatment facility produces TKN (total Kjeldahl nitrogen)concentrations of 275-450 mg/L, and COD(chemical oxygen demand) concentrations of800-3,000 mg/L. The plant’s location experiences high winds and drastic temperature swings that also pose challenges to managing the treatment lagoons and basins. The wastewater treatment facility’s process achieved effluent concentrations of 150-200 mg/L nitrate-nitrogen (NO3-N), enabling the facility to be compliant with its previous effluent TN (total nitrogen) discharge limit of 200 mg/L. However, this level of treatment effectiveness, plant design, and configuration would not be capable of meeting an upcoming new limit for TN of 75 mg/L — putting the facility’s operating permit at risk. --- # VA Poultry-Processing Plant Meets Stringent Nitrogen Limits With EOSi’s MicroC® 2000 and Nitrack® Automation [Case Studies](https://microc.com/resources/case-studies) The Virginia poultry-processing plant packaging up to 200,000 chickens per day requires vast quantities of water sourced from its onsite wastewater treatment plant (WWTP) for processing and rendering offal, blood, and fats. A2010 plant upgrade enabled the WWTP to treat 2million gallons per day (MGD), but the plant struggled to meet stricter standards for biological nutrient removal (BNR) to protect the Chesapeake Bay Watershed. The Virginia Department of Environmental Quality(VADEQ) mandates total mass daily limits (TMDLs) and effluent concentration limits for nitrogen and phosphorus in the treated wastewater. The poultry-processing plant’s WWTP must achieve annual effluent loadings of less than 22,824 pounds of total nitrogen (TN), less than 1,142 pounds of total phosphorus (TP), and must also achieve effluent concentration limits of 6 mg/L of TN and 0.3 mg/L of TP. The plant’s WWTP needed help to achieve VADEQ’s strict BNR standards, and turned to EOSi’s MicroC® 2000 carbon sources and Nitrack® Program automated dosing optimization expertise. --- # Acetic Acid to MicroC® 2000: Virginia WWTP Boosts Savings & EBPR Performance [Case Studies](https://microc.com/resources/case-studies) A Virginia municipal 5 MGD wastewater treatment facility discharging to the Potomac River Basin was recently upgraded to achieve enhanced nutrient removal objectives of 4 mg/L of total nitrogen (TN) and 0.3 mg/L of total phosphorus (TP). The major components of the upgrade included two new five-stage biological reactor trains, two new secondary clarifiers, new primary clarifiers, and new tertiary denitrification filters. The upgrade also involved conversion of existing ditches to plug flow reactors, new solids-processing equipment, and adding chemical storage and feed equipment for 20% acetic acid and aluminum sulfate (alum). The facility was feeding alum to the secondary clarifiers, and optionally feeding alum to the influent of their Parks on Dynasand® continuous-backwash tertiary filters for final trimming of effluent orthophosphate. However, the facility was using VFA (volatile fatty acid) acetic acid as a carbon source for enhanced biological phosphorus removal (EBPR). --- # Axius Water® Acquires Aero-Mod, a Leader in Mechanical and Biological Treatment Jan 9, 2025 [News & Press](https://microc.com/resources/news) **POCASSET, MA USA (January 9th, 2025):** Axius Water (“Axius”), a leading provider of nutrient management solutions for municipal and industrial wastewater treatment facilities, announced today that it has acquired Aero-Mod, a leading supplier of proprietary mechanical/biological wastewater treatment systems based in Manhattan, KS.

Variability in solids, fats, proteins, and loadings can shift frequently making it difficult to maintain stable denitrification. EOSi’s MicroC® provides a quality and sustainable carbon source that performs consistently, every time. [Denitrifying bacteria](https://microc.com/nitrogen) requires readily available carbon to reliably remove nitrate. Most internal waste streams require fermentation or hydrolysis before they become usable which can be an unpredictable process. [MicroC](https://microc.com/products) is specifically formulated for instant biological uptake, enabling rapid responsive nitrate reduction that supports consistent effluent compliance, regardless of what’s happening upstream. **Optimized for Worry-Free Operations** Relying on internal streams often means introducing fats, oils, grease, solids, and other complex organics into your biological nutrient removal (BNR) process which can lead to clogs, odors, inconsistent feed quality and unnecessary operator burden. Alternatively, MicroC is the number one trusted non-hazardous liquid carbon source available that’s easy to store, dose, and maintain. Implementing EOSi’s integrated Nitrack® dosing system, provides further operational support including improved process control, improved carbon efficiency, more stable effluent nitrate, and lower operating cost through accurate dosing. Backed by an award-winning algorithm, MicroC paired with [Nitrack’s](https://microc.com/virtual-nitrack-cloud-based-control-system) custom dashboards and real-time analytics provide operator peace of mind and long-term optimization that internal waste streams cannot offer. **Proven Chemistry, Proven Results** From meat and poultry processors to beverage plants and dairy facilities, [industrial operations](https://microc.com/industrial) rely on EOSi’s MicroC because it delivers consistent, measurable results in nitrate removal, process stability, operational efficiency and safety, automation performance, and overall BNR reliability. [MicroC plus Nitrack](https://microc.com/what-is-nitrack) is the trusted integrated optimization partner used in hundreds of installations across North America, helping facilities regain control of their nutrient removal processes and meet their compliance goals with confidence. While internal waste streams may appear cost-effective on paper, hidden costs, variability, infrastructure requirements, staff time, biological risk, and process instability often far outweigh the perceived savings. MicroC provides a refined, engineered, performance-optimized carbon solution that delivers reliability where it matters most, protecting your compliance, your operations, and your bottom line. **Take Better Control** of Your Biological Nutrient Removal Processes.

Microorganisms introduced in the two-stage nitrification-denitrification process first convert ammonia nitrogen into nitrate, then other microorganisms next convert the resulting nitrate into safe nitrogen gas, removing it from the water. Phosphorus removal also involves using microorganisms to assimilate phosphorus into a biomass that absorbs and eliminates excessive soluble phosphates to prevent environmental harm. Wastewater treatment plant operators grappling with more restrictive permit requirements involving nutrient overload often need better understanding and greater insight into BNR processes to achieve their rapidly changing operational objectives. EOSi’s nutrient removal compliance experts have the application and technical experience to empower operators in their goals of achieving significantly reduced environmental impact at the lowest long-term operational cost. By leveraging the deep expertise and hands-on industry experience of EOSi’s full-service, proven BNR solutions wastewater, operators can stay prepared for the next wave of industry changes while optimizing current processes. EOSi offers a combination of cost-effective nonhazardous premium carbon sources, advanced process-monitoring technologies and specialized nutrient-removal technical services and process optimization. **EOSi’s BNR Fundamentals Professional-Development Course** Plant operators seeking greater BNR expertise can partner with EOSi for industry training programs.

EOSi’s CEU goal: instill essential BNR knowledge and skills enabling plant operators to make vital operational improvements for better control of their biological nutrient removal processes. --- # Cloud-Based Wastewater Automation: Breaking Down the Myths Jul 9, 2026 [Articles](https://microc.com/resources/articles) As wastewater treatment facilities face increasing pressure to meet their nutrient limits, many operators are exploring the benefits of cloud-based automation. Despite the growing adoption of these automation technologies, misconceptions around cybersecurity, reliability, and implementation complexity slow progress. The reality is that modern cloud-based optimization platforms like Nitrack® are designed specifically to operate within the security, reliability, and operational requirements of wastewater treatment facilities. **Myth #1: Cloud-Based Automation Compromises Plant Security** One of the biggest concerns surrounding cloud-based solutions is cybersecurity. Many operators assume that connecting treatment processes to the cloud creates unnecessary risk. In reality, Nitrack® was built with security as a foundational design principle. A compact IIoT gateway collects only a few key process data points from the plant's SCADA system or PLC. Those data points are transmitted through encrypted communication channels protected by stateful firewalls and CA-issued certificates. EOSi's proprietary optimization algorithms operate securely within the cloud environment, ensuring both operational reliability and data protection. For facilities requiring additional isolation, the gateway can also be configured using air-gapped analog signals, providing flexibility to meet site-specific security protocols. The result is a secure architecture that allows facilities to benefit from advanced optimization without compromising existing cybersecurity practices. **Myth #2: Cloud Solutions Require Major Infrastructure Changes** Many treatment plants worry that implementing cloud-based automation means expensive engineering projects, extensive rewiring, or lengthy downtime. Nitrack® takes a different approach. Deployment typically begins with a small IIoT gateway that connects to existing SCADA or PLC systems through a simple Ethernet connection or other straightforward communication methods. EOSi-supplied cellular remote probes eliminate the need for complex field wiring and communicate directly with the cloud. There are no major retrofits, control system overhauls, or disruptive installation projects. The system integrates with existing infrastructure, allowing facilities to begin optimizing carbon dosing quickly and efficiently. **Myth #3: Cloud-Based Optimization Isn't Reliable Enough for Critical Processes** Wastewater operators depend on consistent process performance, particularly when managing nutrient limits. Some assume that cloud-hosted systems introduce unnecessary uncertainty into critical control strategies. In practice, Nitrack® improves process visibility and operational confidence. The platform continuously analyzes real-time process data using EOSi's proprietary algorithms to determine the optimal MicroC® dosing rate. By responding to changing plant conditions, Nitrack® helps maintain stable biological nutrient removal (BNR) performance while reducing the burden on plant staff. Because the system relies on a combination of SCADA data and cellular-based remote monitoring, it can provide reliable dosing recommendations across a wide range of plant configurations. The result is a low-maintenance, high-confidence solution designed specifically for wastewater operations. **Myth #4: Automation Replaces Operational Expertise** Some operators worry that automation means losing control of their process. The opposite is true. Nitrack® is more than a software platform, it's backed by experienced EOSi Process Engineers who continually monitor trends and help facilities identify emerging issues before they become compliance concerns. Operators retain full visibility into their systems while gaining a dedicated team of process specialists acting as a second line of defense. This partnership approach provides facilities with 24/7 support and ongoing optimization assistance, helping plants maximize performance while building long-term operational resilience. **The Future of Secure BNR Optimization** Cloud-based wastewater automation is no longer an emerging concept, it's a proven tool for improving process performance, reducing operational complexity, and supporting increasingly stringent nutrient limits. Nitrack® combines secure IIoT connectivity, advanced cloud analytics, and expert process support into a simple, reliable platform that optimizes MicroC® dosing without disrupting existing operations. By breaking through outdated misconceptions about cloud technology, wastewater facilities can take advantage of smarter nutrient removal while maintaining the security standards they expect. When it comes to BNR optimization, EOSi’s goal isn't simply to sell more carbon source, it's to provide a secure, efficient solution that helps facilities achieve consistent results, minimize risk, and operate with confidence. --- # Don’t Get Fooled – When It Comes to Carbon Sources, Is Cheaper Really Better? Aug 6, 2025 [Articles](https://microc.com/resources/articles) **Carbon Sources are** ***not*** **Created Equal** *Crude Glycerin:* Foregoing reliable quality for low cost is rarely a wise choice, especially when it comes to choosing your glycerin-based carbon sources and provider for biological nutrient removal (BNR). Why? Let’s start by comparing crude glycerin with highly refined carbon sources like EOSi’s MicroC*®*. Typically, generic crude glycerin is produced as a biofuel byproduct and is shipped directly from biofuel manufacturers without extra refining and cleanup steps. Excess fatty substances and impurities, residues, and other included solid materials often cause clogging and residue problems with wastewater treatment processes, pumps, tanks, and handling equipment. Low-quality crude glycerin quality also risks potential process downtime, triggering higher maintenance costs, equipment shutdowns, and staff overtime, risking “operational gaps” that violate plant permit requirements until remedied. Further, crude glycerin’s wide variances in quality control and chemical consistency can make optimizing carbon source feed rates a moving-target operational ordeal. *MicroC® Premium Carbon Sources:* In contrast, highly refined glycerin-based carbon sources like EOSi’s MicroC 2000 undergo extensive manufacturing processes to remove excess levels of impurities and rigorous quality control that guarantee product consistency that prevents the clogged feed lines and pump system failures that can plague crude glycerin users. MicroC undergoes frequent sampling and testing by in-house EOSi testing labs at every step of production and delivery fulfillment, guaranteeing plant operators the highest quality consistency with every batch. Crude glycerin may initially appear cheaper and more cost effective, but potential higher maintenance costs, operational downtime, and permit compliance risk can make it a case of “you might pay less, but you are also going to *get* less.” In fact, poor quality crude glycerin is the most cited reason why plant operators switch to MicroC, and treatment facilities that experience problems operating their biological nutrient removal processes with crude glycerin typically switch back to using MicroC within just a few months — and never return to using crude glycerin again. **“You’re on Your Own” vs. EOSi’s Robust Supply Network & Process Support** *Biodiesel Refineries:* Purchasing crude glycerin directly from biodiesel refineries can present unexpected operational pitfalls for wastewater treatment operators. Biodiesel refineries typically are focused solely on the business of supplying to large mass-market fuel customers rather than serving the exacting and stringent requirements for effective biological nutrient removal processes. Unpredictable batch-to-batch variation in quality and consistency of crude glycerin, hit-and-miss supply availability, and unreliable point-to-point product delivery, can make crude glycerin single-sourced from biodiesel refineries an operational risk for wastewater plants that absolutely require a consistently dependable supply chain for permit compliance. Expecting technical support or help troubleshooting your treatment processes? Biodiesel manufacturers are highly unlikely to provide experienced process expertise if glycerin usage problems arise, and industry expertise specific to optimizing biological nutrient removal operations is almost nonexistent. All you’re going to get from biodiesel manufacturers is the crude glycerin you receive from the tanker when it rolls up to your treatment plant. *EOSi:* Unlike biodiesel refineries, EOSi specializes in manufacturing MicroC premium carbon sources specifically formulated for non-hazardous biological nutrient removal. A robust supply chain network of more than 20 EOSi manufacturing facilities across North America delivers MicroC directly to hundreds of wastewater treatment customers, ensuring reliable and dependable supply regardless of plant location or fluctuating market conditions. Also unavailable from refinery suppliers are sophisticated dosing controls like EOSi’s Nitrack*®* automated system that helps wastewater treatment facilities streamline plant operations, reduce feed rate costs, and enhance process performance. Analyzing fluctuations in influent loading and accurately predicting the precise chemical dosing, EOSi’s Nitrack system dynamically optimizes the feed rate and minimizes unnecessary MicroC usage, boosting efficiencies by reducing feed costs by up to 30%. EOSi’s most differentiating value according to most plant operators: you get EOSi’s expert in-house technical support when you buy MicroC products.

MicroC products undergo stringent and comprehensive QA/QC testing by EOSi’s twenty in-house labs that include rigorous pre-qualification of suppliers and strict control of raw materials prior to manufacturing. Products are analyzed for specifications conformance prior to release for customer shipment, ensuring they are precisely formulated, free of contaminants, and delivering consistent and superior quality. Over a typical 12-month period, EOSi’s QA/QC lab specialists analyze more than 600 raw material samples from more than 20 suppliers and 650 finished product samples from EOSi’s 20 North American manufacturing facilities. EOSi’s comprehensive QA/QC laboratory analysis capabilities include: • NUR (nitrate utilization rate) • PUR (phosphorus uptake rate) • Respirometry • Microscopy • Near-infrared spectroscopy • Wet chemistry analysis (NH3, NO3, NO2, TN, TP, PO4-P, alkalinity DO) • Gas chromatography-flame ionization detection (GC/FID) for alcohols and volatile fatty acid (VFA) quantification Finished MicroC products are documented with official lab-prepared certificates of analysis (COA), an industry-standard formal document detailing conclusive laboratory testing results signed by the authorized lab conducting the analyses, with finished product samples retained for at least six months for verification and comparison. **The EOSi Advantage: Evolving for Excellence** Continuous improvements to EOSi’s labs located at each manufacturing facility include technology advancements and equipment upgrades enhancing testing accuracy and process efficiency. EOSi’s labs use gas chromatography (GC) and flame ionization detection (FID) technology for analyzing alcohols, esters, and ketones. Used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition, GC typically requires using tanks of helium, a “zero-air” gas that is a finite resource in danger of planetary depletion. EOSi’s lab converted their GC/FID equipment to run instead on hydrogen gas they now produce themselves in the lab, eliminating helium usage and its high cost, lowering the lab’s carbon footprint, and creating a safer environment by eliminating the safety hazard of onsite pressurized tanks. Specialized high-purity water generation equipment now converts municipally sourced water into high-purity deionized (DI) water used with the new hydrogen generator to create hydrogen gas, boosting sustainability and enhancing the testing accuracy. The labs also use near-infrared (NIR) spectroscopy using handheld analyzers for quality control and monitoring chemical parameters of samples, especially useful for “wet-chem” testing and real-time analysis at field locations. Handheld NIRs deployed remotely from EOSi’s lab locations across the United States enable access to accurate real-time data that accelerates product decisions and streamlines manufacturing processes. **Resilience Through Diversification** Upgrading lab equipment across all EOSi labs enables resource duplication as critical backup to eliminate operational downtime resulting from equipment failure, and enabling access to additional on-demand lab resources when needed for processing large batches of chemical samples more quickly. The lab upgrades also deliver a vital measure of systems redundancy: multiple components or processes that can perform the same functions, yet operate independently and adaptively — resource duplication as “backup,” but also resilience through diversification. Skill diversification and team cross-training is also part of EOSi’s continuous improvement cycle. Lab specialists with exclusive expertise train other team members so mission-critical operations don’t unexpectedly halt when staffers with vital skills become ill or absent. Cross-training can also reveal hidden or undiscovered process improvements and manufacturing efficiencies that result in direct benefits to EOSi customers. Continuous improvement of EOSi’s lab testing capabilities and multilayer quality control from procured raw materials through finished product ensures MicroC customers receive products certified to meet or exceed stringent standards and expectations. The gatekeepers and guarantors of MicroC product quality, EOSi’s lab team are the customer’s advocate for helping them cope with ever-changing plant processes and permit requirements to achieve and maintain regulatory compliance for biological nutrient removal. --- # MicroC® 1000 vs. Other Carbohydrate-Based Carbon Sources Aug 12, 2026 [Articles](https://microc.com/resources/articles) In biological nutrient removal (BNR) applications, selecting the right supplemental carbon source can significantly impact treatment performance, operational safety, and overall costs.

Expanding industry demand for MicroC as a non-hazardous and cost-effective alternative to using methanol accelerated EOSi’s transformation into the high-growth industry leader in biological nutrient removal it is today. ## Nonhazardous Impact Wide industry acceptance of nonhazardous carbon sources like refined-glycerin MicroC® 2000 have rendered older methanol-based carbon supplement systems almost obsolete — with no new U.S. methanol-based installations reported in the past five years. Why? Flammability and toxicity safety concerns, costly flammable-liquid storage and feed systems, and unsustainably of fossil-fuel derived imported methanol carbon sources. In contrast, non-hazardous and agriculturally renewable MicroC carbon sources offer cheaper use and storage, rapid and flexible deployment, superior cold weather performance, and more. ## Engineered Solutions EOSi’s MicroC® — the world’s leading non-hazardous supplemental carbon sources have become a recognized industry standard widely used in denitrification, enhanced biological phosphorus removal (EBPR), and biochemical oxygen demand (BOD) addition applications. EOSi’s Nitrack® control system is the wastewater treatment industry’s first PC-based controller for biological nutrient removal applications, enabling plant operators to continuously monitor and optimize their unique treatment processes.

Search FAQs ### Biological Nutrient Removal Questions What are Supplemental Carbon Sources? Supplemental carbon sources are readily biodegradable organic compounds added to wastewater to supercharge the growth of helpful bacteria. These bacteria are the unsung heroes of biological wastewater treatment, breaking down pollutants and keeping systems running efficiently. What is MicroC® used for? [MicroC® Premium Carbon Sources](https://microc.com/products) help establish or sustain essential biomass within a wastewater treatment plant that is responsible for promoting biological removal of harmful nutrients and contaminants including nitrogen, phosphorus, perchlorate, and selenium. This process is commonly referenced to as Biological Nutrient Removal (BNR). How does MicroC® compare to Methanol? MicroC® offers a safer, more sustainable alternative to methanol. It’s non-hazardous, easier to store and handle, and performs better in cold weather. Plus, because it's biogenic (derived from natural sources), glycerol-based MicroC can help facilities reduce their Scope 1 greenhouse gas emissions—unlike methanol, which contributes to CO₂ emissions according to ICLEI. Switching to MicroC is a smart move for both the environment and your bottom line. ## See Nitrack in Action!

[Contact Us](https://microc.com/contact) --- # Selenium / Perchlorate EOSi provides targeted electron donor solutions to support the biological removal of selenium and perchlorate, helping facilities meet stringent discharge limits while protecting downstream ecosystems and water quality. ## SELENIUM & PERCHLORATE **Reducing Environmental Risk** with Custom Targeted Solutions Toxic contaminants released to soils, groundwater, and waterways include perchlorate from the improper disposal of explosives and rocket/missile propellants, and metals containing the element selenium generated in coal, copper, and zinc mining. Perchlorate is now present in many potable water supply wells, and can have harmful effects on thyroid function if ingested, especially among women and infants. Biological treatment of perchlorate is very similar to denitrification, and denitrifying bacteria have been found to be capable of degrading perchlorate. Toxic metals containing the element selenium generated in coal, copper, and zinc mining are increasingly contaminating soil and waterways, particularly inflicting harm on egg-laying animals, including fish, birds and other wildlife. Like with perchlorate, biological treatment is also a cost-effective option for removing dissolved selenium from wastewater. ##### EOSi’s tailored treatment solutions for selenium and perchlorate removal help mitigate environmental risks like soil and waterway contamination which can lead to harmful effects for both biological health and wildlife. ## How EOSi Can Help Perchlorate can be removed from drinking water or groundwater by physical-chemical processes such as ion exchange or reverse osmosis, but these processes produce waste brine that can be challenging to manage. A safer and effective alternative for removing perchlorate from drinking water and groundwater is biological treatment using MicroC® as a carbon source and electron donor. Likewise, biological treatment is a cost-effective option for removing dissolved selenium from wastewater. In this process, microbes use a carbon source such as MicroC as an electron donor to trap selenium in the biomass. In addition to our traditional MicroC Carbon Sources, EOSi has developed [MicroC® 4000](https://microc.com/products/microc-4000) which can be used to remove nitrate and perchlorate in potable water systems. - [Case Study ### Molasses to MicroC: PA Coal-Fired Power Generation Station Meets Nitrate & Selenium Reduction Goals with MicroC® 4100](https://microc.com/resources/case-studies/papower) **Take Better Control** of Your Biological Nutrient Removal Processes.

Occasionally, an additional “food source” such as refined-glycerin MicroC® 2000 needs to be added to treatment systems to promote essential bacterial growth and reproduction. This biochemical oxygen demand (BOD) supplementation process is distinct from adding an external carbon source to facilitate removal of specific contaminants. However, activated sludge (AS) wastewater treatment systems can lose as much as 10-15 percent of their essential biomass daily due to endogenous decay — the metabolism of the biomass itself to sustain life. If the BOD of the wastewater is too low to support enough microbial growth to overcome that endogenous decay, the system will start experiencing operational problems and/or be unable to achieve treatment goals. BOD supplementation can be an effective way to avoid and address these operational problems. MicroC® Carbon Sources for BOD addition can help promote microbial growth until stable biomass is achieved during periods of seasonal reductions, new plant startup, temporary shutdown/maintenance, or other process changes. ## How EOSi Can Help Occasionally, a biological treatment system will require establishing a new microbial population, either because the system is new or because it has experienced a process upset that harmed the biomass, and biochemical oxygen demand supplementation can support and promote microbial growth until a stable biomass is achieved. Industrial facilities also shut down for annual or periodic turnaround maintenance, and their biological wastewater treatment systems need BOD supplementation to keep their microbial populations alive during these temporary shutdowns. EOSi’s technical team works with treatment plant operators to conduct respirometry and other tests to evaluate how the biomass will acclimate to [MicroC® 2000](https://microc.com/products/microc-2000) products, as they provide a consistent BOD source with well-defined kinetic and yield characteristics. The EOSi team also helps calculate proper MicroC 2000 feed rates, recommends operational adjustments, and provides guidance on process monitoring to ensure a viable biomass is established. When time is critical — especially with process upsets — EOSi’s robust supply chain helps operators to quickly mobilize and provide the BOD source needed to get their treatment system functioning again. - [Case Study ### Midwest WWTP Overloaded by Industrial Influent Rescued from Permit Probation by EOSi’s MicroC® 2000](https://microc.com/resources/case-studies/inwwtp) - [Case Study ### MicroC® Supports Biomass During Startup, Shutdown and Variable Loadings](https://microc.com/resources/case-studies/bod-supplementation) **Take Better Control** of Your Biological Nutrient Removal Processes.

[Contact Us](https://microc.com/contact) --- # Nitrogen EOSi’s MicroC® products were originally developed to help wastewater treatment systems remove nitrogen. ## DENITRIFICATION Protecting Environmental Resources by **Supporting Biological Nitrogen Removal** Biological nutrients such as nitrogen and phosphorus are essential for the growth of all living organisms, but excessive amounts of nutrients released to the environment by human activities can harm ecosystems and impact human health. Excess nitrogen deteriorating water quality in many freshwater bodies worldwide is causing drinking water contamination, oxygen-depleted waterways, habitat damage, algal blooms, and fish kills. Nitrogen in drinking water also poses health risks to infants and pregnant women, particularly in agricultural areas where groundwater wells are the primary source of drinking water. Elevated concentrations of nitrogen in drinking water create nitrate compounds causing “blue baby syndrome” methemoglobinemia, a potentially fatal illness in which the nitrates reduce the oxygen-carrying capacity of the blood. ##### Excess nitrogen from wastewater discharges can fuel harmful algal blooms in natural water bodies. EOSi’s refined-glycerin MicroC® 2000 support enhanced denitrification processes, helping treatment facilities reduce nitrogen levels and protect aquatic ecosystems. ## How EOSi Can Help EOSi’s MicroC® [products](https://microc.com/products) are uniquely suited for use in biological processes that help remove nitrogen from wastewater. With wastewater treatment plants increasingly required by state and federal regulatory agencies to reduce the amount of nitrogen discharged into sensitive watersheds, EOSi offers services that help customers assess, develop, implement, and update their compliance strategy for nitrogen removal programs. MicroC serves as a carbon source to support biological nitrogen removal (BNR) using denitrification to convert nitrates in the wastewater into harmless water, nitrogen gas (N2), and carbon dioxide gas (CO2). A biological process that takes place under anoxic conditions, denitrification occurs after aerobic bacteria converts ammonia to nitrate in a nitrification process. Often there is insufficient organic material to support denitrification, therefore a carbon source such as MicroC is added to the process to convert nitrate to nitrogen gas. - [Case Study ### EOSi’s Nitrack® Carbon Source Automation Make Florida County WWTPs Low-Nitrogen Compliant](https://microc.com/resources/case-studies/flcounty-mwwtf) - [Case Study ### HRSD Intensifies Dentrification, Securing Savings & Compliance with Bio-Based MicroC® 3000](https://microc.com/resources/case-studies/hrsdwwtp) - [Case Study ### NC Reclamation Facility Boosts Denitrification & Compliance While Reducing MicroC® 2000 Cost](https://microc.com/resources/case-studies/ncwrf) **Take Better Control** of Your Biological Nutrient Removal Processes. [Contact Us](https://microc.com/contact) --- # Phosphorus EOSi’s services help customers develop, implement, and update their compliance strategy for removing harmful nutrients, and EOSi’s MicroC® products are uniquely suited for use in enhanced biological phosphorus removal (EBPR) processes. ## EBPR Quality & Cost-Effective Solutions for **Enhanced Biological Phosphorus Removal** Like nitrogen, excessive phosphorus discharges entering freshwater systems damages water quality and aquatic habitats, causing harmful drinking water contamination, algal blooms, and fish kills. Phosphorus-fed algal blooms blocking sunlight and consuming dissolved oxygen in the water also produce toxins and encourage bacterial growths that sicken people who swim in or drink the water, or who eat tainted fish or shellfish. Phosphates are found naturally in soils, animals, and plants, but other significant sources of phosphates in the environment include man-made fertilizers, soil erosion and runoff from mining and agricultural activities, cleaners and detergents, animal wastes, and sewage and septic systems — resulting in today’s strict environmental regulations governing phosphorus discharge limits for wastewater treatment plants. ##### EOSi provides reliable refined-glycerin carbon solutions to support Enhanced Biological Phosphorus Removal (EBPR), helping wastewater treatment facilities improve phosphorus removal performance and meet stringent effluent limits. ## How EOSi Can Help EOSi’s [services](https://microc.com/nitrack-services) help customers develop, implement, and update their compliance strategy for removing harmful biological nutrients, and EOSi’s MicroC® products are uniquely suited for use in enhanced biological phosphorus removal (EBPR) processes. EBPR uses a series of anaerobic, anoxic, and aerobic reactors designed to encourage the growth of phosphorus-accumulating organisms (PAOs), removing phosphorus from the wastewater treatment system as part of a waste biological sludge. Glycerol-based carbon sources such as [MicroC](https://microc.com/products) 2000 are added to the anaerobic reactors to provide the PAOs with a readily available food supply that is necessary to facilitate the EBPR process. EBPR is gaining in popularity as it is viewed as a more sustainable method of removing phosphorus compared to chemical phosphorus removal that require metals such as iron and aluminum that bind with the phosphorus. - [Case Study ### Acetic Acid to MicroC® 2000: Virginia WWTP Boosts Savings & EBPR Performance](https://microc.com/resources/case-studies/vawwtp) - [Case Study ### Midwest Reclamation EBPR Evaluation: Assessing MicroC® 2000 For Ample Phosphorus Reduction](https://microc.com/resources/case-studies/mwwrf) - [Case Study ### Transforming EBPR: Non-VFA Pathway Success With EOSi’s MicroC® 2000](https://microc.com/resources/case-studies/mdmwrp) **Take Better Control** of Your Biological Nutrient Removal Processes.

Historically, nitrate and perchlorate have been removed from drinking water using physical/chemical treatment processes such as ion exchange or reverse osmosis. Although effective, these processes produce waste brines that are difficult and expensive to manage, especially when treating water with high concentrations of contaminants. Biological treatment has the advantage of converting nitrate and perchlorate into harmless compounds, and is often less expensive. The water industry’s extensive experience using biological treatment for wastewater is readily transferable to drinking water. As in wastewater treatment systems, bacteria reduce nitrate to nitrogen gas and perchlorate to chloride ions under anoxic conditions. Instead of the activated sludge systems common in wastewater treatment, drinking water treatment typically uses fixed bed, fluidized bed, or membrane bioreactors. Unlike most wastewaters, drinking water sources do not contain readily biodegradable organic compounds that will support microbial growth. In addition, drinking water treatment requires post-treatment to produce a final product with acceptable turbidity, taste, and odor. ##### Harmful nutrients and contaminants in drinking water is a growing concern in the United States, but EOSi has demonstrated the effectiveness of advanced biological treatment using MicroC® carbon sources to remove nitrate and perchlorate from drinking water. ## How EOSi can help To create the necessary anoxic conditions, a carbon source such as MicroC® must be added in sufficient amounts to support bacterial growth that depletes the dissolved oxygen. Additional MicroC is then needed to serve as an electron donor in the microbial processes of denitrification and perchlorate biodegradation. EOSi’s [MicroC® 4000](https://microc.com/products/microc-4000) carbon sources are designed for drinking water applications. MicroC 4000 can be custom formulated to provide any necessary microbial nutrients, such as phosphorus, that may not be present in sufficient amounts in the drinking water source. EOSi also provides services such as bench-scale analyses, modeling and simulations, and equipment selection and procurement for water treatment plants evaluating using biological treatment for drinking water. **Take Better Control** of Your Biological Nutrient Removal Processes. [Contact Us](https://microc.com/contact) --- # Groundwater Remediation EOSi delivers proven solutions for groundwater remediation, helping environmental professionals restore contaminated sites with effective, science-backed treatment strategies. ## GROUNDWATER REMEDIATION Boosting **Nitrogen, Selenium & Perchlorate Removal** Cost-Effectively Biological treatment is often a more cost-effective way to remove contaminants from groundwater than physical or chemical treatment, with the added benefit of converting the contaminants into harmless compounds. In contrast, groundwater contamination is often remediated and/or hydraulically contained using an ex-situ “pump-and-treat” approach, in which the groundwater is pumped from wells, treated to remove the contaminants, and either reinjected into the aquifer or discharged to the surface. Groundwater pump-and-treat may be a feasible treatment choice for contaminant plumes from point sources. Mining operations, chemical and fertilizer plants, petroleum refineries, and concentrated animal feeding operations (CAFOs) are potential point sources of contaminants. Pump-and-treat is generally not cost effective or feasible for treating widespread contamination from nonpoint sources, such as nitrate contamination of groundwater due to general agricultural activities. ##### Contaminants in groundwater can harm valuable drinking water and irrigation supplies and can damage aquatic environments in areas where contaminated groundwater discharges to surface water, but EOSi’s MicroC® premium carbon sources can be used to support biological treatment of groundwater contaminated with nitrogen, perchlorate, and selenium. ## How EOSi can help EOSi’s [services](https://microc.com/nitrack-services) help remediation contractors design and implement MicroC® programs for groundwater treatment. Biologically treating nitrogen compounds may require nitrification in an aerobic reactor to oxidize ammonia and ammonium to nitrate and nitrite, followed by denitrification in an anoxic reactor to covert the nitrates and nitrites to nitrogen gas. Denitrifying bacteria will also degrade perchlorate, reducing it to chloride ions. When neither oxygen nor nitrate is present, microbes will use the forms of selenium typically found in water (selenate and selenite) as electron acceptors, producing elemental selenium that precipitates or is trapped in the biomass. MicroC helps establish and maintain the healthy biomass needed for removal of nitrogen, perchlorate, and selenium from groundwater. Unless the groundwater is also contaminated with organic compounds, there may not be enough biodegradable organics to support the biomass needed for nitrification in the aerobic zone. Denitrification and degradation of perchlorate and selenium in the anoxic zone occurs after the aerobic bacteria have already oxidized any biodegradable organic compounds. In both cases, the biomass will need a carbon source such as MicroC that provides readily available food and energy. MicroC can be custom blended to provide other essential microbial nutrients, such as phosphorus, that may not be present in sufficient quantities in the groundwater. **Take Better Control** of Your Biological Nutrient Removal Processes.

EOSi can conduct nutrient deficiency analyses and, if necessary, design a [custom blend](https://microc.com/products/microc-4000) that includes essential microbial nutrients not found in the mining wastewater. ## Landfill Operators EOSi can help landfill operators remove ammonia and other nitrogen compounds from leachate, applying MicroC® premium carbon sources to support microbial populations needed for biological nitrogen removal (BNR) converting nitrogen compounds into harmless nitrogen gas. Leachate from older landfills may lack sufficient biodegradable organic compounds to support the biomass needed for nitrification in the aerobic zone, so a supplemental carbon source such as MicroC that provides readily available food and energy will be needed, regardless of landfill age. MicroC can be [custom blended](https://microc.com/products/microc-4000) to provide other essential microbial nutrients, such as phosphorus, that may not be present in sufficient quantities in the leachate. EOSi refines the MicroC program as needed to accommodate changing leachate characteristics in landfills over time. - [Case Study ### MicroC® Supports Biomass During Startup, Shutdown and Variable Loadings](https://microc.com/resources/case-studies/bod-supplementation) --- # Municipal EOSi partners with domestic facilities to deliver advanced wastewater treatment solutions enhancing nutrient removal, improving operational efficiency, and protecting vital water resources. ## MUNICIPAL **\#1 Trusted by Domestic Facilities** for Supplemental Carbon & BNR Solutions Publicly owned treatment works (POTWs) and other domestic wastewater treatment systems can be significant point sources of harmful nutrients in aquatic environments, and state environmental regulatory agencies are increasingly developing new or more stringent standards limiting nitrogen and phosphorus discharges to protect water quality. Biological treatment to remove nitrogen and phosphorus is often more cost-effective than physical or chemical treatment technologies, with the added benefit of converting the contaminants into harmless compounds. POTWs sometimes experience operational difficulties with activated sludge systems, such as foaming, bulking, or poor settling. In these situations, a low food-to-microorganism ratio (F/M) may be promoting the proliferation of undesirable filamentous bacteria. BOD augmentation to increase the F/M ratio can resolve or prevent many such operational problems, is also useful for sustaining biomass during seasonal periods of low flows or loadings, and for establishing the biomass during start-up of new or upgraded biological treatment systems. ##### EOSi assists municipal wastewater treatment plants, decentralized/package, and commercial/residential facilities to develop compliance strategies for meeting increasingly stringent requirements for reducing biological nutrient discharges. ## How EOSi Can Help EOSi’s [MicroC®](https://microc.com/products) 2000 refined-glycerin carbon sources enable safe and cost-effective biological removal of nitrogen and phosphorus, and can help treatment plants prevent or resolve operational challenges with activated sludge systems during plant startups or during events of inadequate food to microorganism ratio. The well-defined kinetic and yield characteristics of MicroC also make it ideal for BOD augmentation. From assessment, trouble shooting, automation, and optimization, EOSi’s goal is to maximize nitrogen and phosphorus removal from existing biological treatment systems, preferably through operational improvements instead of capital investments. If wastewater plants need to install new or upgraded biological treatment systems, EOSi can perform bench-scale treatability studies, modeling and simulations, and equipment selection and procurement for the carbon source supplementation program. EOSi also provides long-term technical support, monitoring, and ongoing optimization services delivered in our Nitrack® Program to our MicroC customers. **Take Better Control** of Your Biological Nutrient Removal Processes.
