摘要

As Water Resource Recovery Facilities (WRRF) effluent nutrient limits are becoming increasingly strict, upgrades to Biological Nutrient Removal (BNR) is inevitable. Retrofitting existing plants to BNR on a tight budget is not unusual. WRRFs are required to meet the more stringent permit requirements for nutrients while under pressure from the communities to keep the user rates at a reasonable rate. Nutrient removal is often stereotyped with additional costs for WRRFs. A case study of a large WRRF in Illinois proves that a holistic review of the WRRF requirements can help facilities leverage larger projects that initiate improvements for regulatory changes, nutrient removal, energy efficiency, and equipment replacement. In this work, North Shore Water Reclamation District's (NSWRD) obtained energy savings and nutrient removal by leveraging their existing tankage to use for Sidestream Enhanced Biological Phosphorus Removal (S2EBPR) without sacrificing permitted capacity or operational simplicity.
