ABSTRACT:
A wastewater treatment apparatus including a biotreatment tank and a floating clarifier within the tank. The floating clarifier includes a floating base and a perimeter wall mounted to and beneath the floating base. A plurality of tented panels mounted to the clarifier walls forms an apertured bottom of the floating clarifier having a plurality of tortuous outlets. The biotreated wastewater from the biotreatment tank enters the floating clarifier, where the suspended solids within the biotreated water settle and descends out of the apertured bottom of the clarifier. The biotreatment tank and clarifier operate continuously while equalizing variations in the wastewater feed rate.
