STM-Aerotor Process and COP Secondary Clarifiers
WesTech’s STM-Aerotor Process and COP Secondary Clarifiers have proven effective in removing biological nutrients and improving water quality at the Patchogue Wastewater Treatment Plant. They have worked together to reduce carbonaceous biochemical oxygen demand (CBOD), total suspended solids (TSS), and total nitrogen (TN) to well below the mandated levels, making the Patchogue WWTP one of the most efficient plants in the state.
