Nutrient Recovery Using OSTARA with WASSTRIP and Multiform Harvest Client: Gwinnett County Department of Water Resources Location: Buford, GA To address struvite issues and a stringent phosphorus limit (0.08 mg/L) at F. Wayne Hill Water Resources Center (FWHWRC), Gwinnett County undertook a pilot program and business case evaluation to assess the potential for a nutrient recovery process that treats phosphorus and ammonia while producing marketable fertilizer as a by-product. Project Outcomes and Benefits Precipitating struvite for use as a slow-release fertilizer helps meet lower phosphorus limits, while creating a new revenue stream, osetting operating costs. The pilot scale testing validated two technologies capable of recovering phosphorus and ammonia as fertilizer product. Net presen
