ABSTRACT:
Disclosed is a single basin, fill and draw wastewater treatment apparatus and method having a unique influent delivery manifold which delivers the incoming influent into a first zone that prevents hydraulic turbulence or short circuiting of un-treated influent from degrading the effluent quality during the decant phase of its cycle while continuously accommodating influent flows and reduces the internal hydraulic velocities to a slow enough rate to utilize the settling sludge blanket as a natural biological filter to absorb and treat influent flows during the air/off phase of its cycle.
