Description

The purpose of this project was to perform a cost evaluation of implementing nitrogen limits of treatment (LOT) technology at wastewater treatment plants (WWTPs) in the Chesapeake Bay Watershed. LOT technology was defined as technology that would produce a 12 month average effluent total nitrogent (TN) concentration of 3mg/L from each of the WWTPs. Most of this effort was a follow up to the evaluation of 51 WWTPs performed under a previous project entitled, "Evaluation of Wastewater Treatment Plants for BNR Retrofits using Advances in Technology".
