As part of the upgrade effort, the County has also commenced two projects designed to reduce the nitrogen concentration in wastewater effluent discharged from the facility. The first project, Biological Nutrient Removal (BNR), has been completed and is in service. Modelling studies indicate that BNR should reduce nitrogen from 35 mg/L to a target range of 13 mg/L. The second nitrogen reduction project is the Deammonification (Sidestream) Treatment Process. The design phase has been completed and the project is currently in construction. It is anticipated that this technology will remove ammonia-nitrogen by 90 percent or greater and 80 percent or greater of total nitrogen.
