South Florida WRF Evaluates & Switches from Methanol to Nonhazardous MicroC® 2000 for Enhanced Filter Denitrification

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?
