VA Poultry-Processing Plant Meets Stringent Nitrogen Limits With EOSi’s MicroC® 2000 and Nitrack® Automation

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.
