A wastewater treatment system for treating wastewater by processes which include aeration. The system includes an influent conduit for delivery of wastewater to be processed and a treatment tank for processing of the wastewater. Also included is an air conduit for providing compressed air for aeration of the wastewater and a particle size regulation device disposed between the conduit and the tank, wherein the particle size regulation device regulates a size of particles present in the wastewater to provide particle size regulated wastewater. The system also includes at least one aeration jet having a nozzle diameter sized to allow the particle size regulated wastewater to pass through the nozzle.

System for the treatment of wastewater

A pressure responsive valve assembly for use in a decanting apparatus for a wastewater treatment reactor. The valve assembly includes a cylindrical valve plate, a valve member support structure, a valve spring, and a valve member comprising a valve stem and a valve head. A discharge passageway extending through the valve plate has a frusto-conical valve seat located therein. The valve head also has a frusto-conical design having an angle of divergence smaller than that of the valve seat so that when the valve head is biased against the valve seat by the valve spring, the valve seat sealingly engages a peripheral edge of the valve seat. The valve member support structure maintains the valve member in proper alignment with the valve seat and in engaging relationship with the valve spring. The valve assembly is configured so as to reduce the ability of sludge to pass through the valve during mix cycles or to settle on the valve assembly during settling cycles of a wastewater treatment process thereby reducing the possibility that such sludge will subsequently be withdrawn from the reactor with decanted liquid during the decanting cycle.
