Primary Treatment

Primary Settling

Wastewater settles in long tanks called primary clarifiers. Heavy material settles to the bottom, and light material floats to the top. All settled material removed in "Primary Treatment" is pumped onto the solids handling process to be thickened and sent for further processing in the anaerobic digesters. The primary treated water (primary effluent) now flows to the Secondary Treatment processes. The two Secondary Treatment processes are Conventional Activated Sludge and Membrane Bioreactor"
