Abstract: A removable submersible pump filter is characterized in a preferred embodiment by a cylindrical screen having a selected mesh size and sized to fit over the pump housing of a submersible pump and motor combination. A pair of typically plastic split screen collars are fitted to the top and bottom of the screen and may be provided with collar openings and a collar bolt and nut, respectively, for removably tightening and securing the screen and the split collars on the pump housing. Alternatively, the resiliency of the split screen collars provide sufficient tension to secure the split collars and the screen on the pump housing. A filter medium having selected filtering characteristics may be placed inside the filter screen adjacent to the pump suction openings for filtering water or other liquid flowing into the pump through the suction openings.

Abstract: A wastewater treatment system characterized by a typically underground filter for filtering inlet wastewater and dispensing the filtered wastewater directly into the ground or into a typically underground treatment system of selected configuration, where ultraviolet lamps and/or chlorine or other disinfectant treatment are provided. In a preferred embodiment the filter includes a filter mount or receptacle fitted with a basket-type filter for filtering wastewater entering the filter receptacle at the top and flowing through the basket filter and from the filter mount at or near the bottom. The filtered effluent is discharged into the ground or routed through a treatment piping system that contains either a chlorine solution or other disinfectant and/or one or more ultraviolet lamps, for disinfection. The treated and disinfected effluent is then routed to a holding or treatment tank or collection vessel of choice or to a distribution system.
