This case study analyzed phosphorus (P) removal from municipal wastewater during the past four summer permit seasons at the Greene County Sugarcreek Water Resource Reclamation Facility. The facility has utilized both chemical removal and enhanced biological phosphorus removal (EBPR)
to provide supplemental P removal in excess of metabolic P removal in order to comply with concentration-based effluent P limits. Both methods were demonstrated to achieve an effluent total phosphorus (TP) concentration less than 0.5 mg/L. Alum was utilized for chemical phosphorus removal.
The EBPR process was a first-of-its-kind with ContinuouslySequencing Reactor (CSR) technology developed by Schreiber coupled with single-stage, variable-output centrifugal blowers provided by Turblex.
