Using a Pay for Performance Contract to Deploy an Innovative Phosphorus Removal Technology
Abstract
The waters of the lower St. Johns River, Florida are experiencing more frequent harmful algal blooms (HABs) from excess total phosphorus (TP) loading due to nonpoint and point source discharges. The St. John River Water Management District (SJRWMD) has funded one of Florida’s first “pay for performance” project to provide high performance effluent treatment at the Fleming Island Wastewater Treatment Facility (FIWWTF) owned and operated by the Clay County Utility Authority (CCUA). The Sustainable Water Infrastructure Group (SWIG) designed, engineered, and installed a 46,500-sq.ft. Phosphorus Elimination System (PES) to treat 2 mgd per day of tertiary effluent with elevated TP. Over the past year, flow weighted inflows were 0.730 mg/L, while flow weighted outflows were 0.065 mg/L, a 91% removal percentage.
The waters of the lower St. Johns River, Florida are experiencing frequent harmful algal blooms (HABs) from excess total phosphorus (TP) loading. A pay for performance contract was used to demonstrate an innovative P removal technology which reduces the risk of a publicly funded project while validating the systems TP removal capabilities. The Sustainable Water Infrastructure Group (SWIG) designed, engineered and installed a 46,500-sq.ft. Phosphorus Elimination System (PES) to treat 2 mgd of tertiary effluent with elevated TP. Over the past year, flow weighted inflows were 0.730 mg/L, while flow weighted outflows were 0.065 mg/L, a 91% removal percentage.
