Featured Story

Salisbury Retrofits Existing Process with an AquaPASS® System to Comply with the Chesapeake Bay Initiative

The Salisbury Township WWTP in Gap, PA utilized a conventional activated sludge (CAS) system prior to being retrofitted with an AquaPASS Phased Activated Sludge System in May 2008. The upgrade was necessary in order to comply with the Chesapeake Bay Initiative for local impaired waterways, requiring stringent permit limits on effluent Total Nitrogen and Total Phosphorus by 2010.
