ABSTRACT:
System for the biological purification of wastewater influent to facilitate the aerobic, anoxic, anacrobic treatment phases of the activated sludge extended aeration technology having an inlet to continuously accommodate influent flows and requiring no outlet and accomplishing all of the functions of flow equalization, high efficiency mixing, biological oxidation, nitrification, denitrification, clarification (secondary sedimentation) and aerobic sludge digestion in a single basin without a quiet or calmed zone adjacent the outlet created by a floating partition, sludge collection trough, sludge recirculation duct, or sweeping devices. The system incorporates an omni-directional partition assembly adjacent the inlet and an aerator assembly having flexible conduit air supplies attached to bottom aerators.
