Henrico County Water Reclamation Facility (WRF) is located near Richmond, VA and discharges to the James River. The facility has had to achieve increasingly stringent nutrient standards. Starting in January 2011 the standards will decrease to TN ≤ 5 mg/L and TP ≤ 1 mg/L on an annual average mass balance limit. The facility has three generations of BNR aeration tanks with the first set of BNR tanks installed in the 1980's. The third and latest generation BNR tanks were recently constructed and are scheduled to be placed in service in December 2010. The paper will present the lessons learned from a 10 year operational period of progressive improvements and optimizations in the three sections:

Section 1: Plant infrastructure and process configuration refinements

Section 2: Operational optimization

Section 3: Supplemental carbon selection and addition

Keywords: BNR; Optimization; Supplemental Carbon

Document Type: Research Article
