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.

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.

Abstract: A modular decanting apparatus that is self supporting that may be used in single or multiple configurations to accommodate the removal of wastewater effluent from a wide range of geometric configurations of basins and sizes while substantially reducing the overflow velocities created during a decanting process. It's "Stove Pipe" configuration provides the option of effluent discharge from its top, bottom or mid section and allows effluent to be discharged by internal pump pressure, external pump suction or by gravity flow according to engineering choice. The apparatus includes a weighted support base, and the stove pipe is captured and surrounded by a buoyant doughnut shaped manifold containing fluid inlet valves and a flexible hose with a straight section connecting the manifold to the interior of the stove pipe assembly and also includes a larger flexible hose connecting the stove pipe assembly to the discharge system of a wastewater treatment reactor.

Abstract: Disclosed is an aeration system for use in a liquid filled basin such as a wastewater treatment process and is particularly effective in a fill and draw system which requires a cyclic operation and includes air diffusion, liquid separation and decanting. The aeration system comprises an aerator which is supported by an air-filled bladder which, when inflated, raises the aerator to a position above the basin floor but when deflated allows the aerator to settle and rest on the bottom of the basin floor during the air/off settling phase and the weight of the aerator pulls the bladder and its hose supply line beneath the liquid surface of the basin thus clearing the top liquid surface. The system may take the form of a train which is affixed traversely across the basin consisting of multiple bladders and aerators which, due to the normal eddies and turbulence created by the aeration process, wander in a random pattern thus providing additional mixing other than aeration.

Abstract: A decanting apparatus for a waste water treatment reactor which includes a float system which may be independent of the decanting apparatus end which allows the decanting apparatus to be removed without removing the float system. The decanting apparatus is a unique ball-funnel-shaped sleeve combination which may be powered internally or externally for removal of effluent that allows decanting below the surface at the most optimum level and may be intermittently operated on demand by floating switches or a programable timer. The decanting apparatus may be utilized in various applications including a gravity flow situation and two or more of these decanting apparatus's may be combined to provide more volume of effluent if required. This decanter is also ideal for environments where lower temperature extremes may form ice upon the upper layer of the fluid within the reactor.

Abstract: A wastewater treatment system is disclosed which utilizes only one fiberglass tank which has no compartments but includes a first flow equalization collector surrounded by a cylindrical partition which vertially eliminates hydraulic turbulence and creates a pre-strat zone. A novel floating decanter is disclosed and programmable circuitry including timing of aeration, liquid levels and decanting processes with the results of producing a quality supernatent affluent heretofore unavailable in such a simple system.
