EOSi’s Nitrack® Carbon Source Automation Make Florida County WWTPs Low-Nitrogen Compliant

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?
