ABSTRACT:
A self-cleaning discharge system used with a wastewater treatment system. The wastewater treatment system includes a tank for collecting wastewater while the wastewater typically includes solid particles. The discharge system comprises a housing, a filter positioned in the housing, an effluent discharge apparatus positioned inside the filter, and a venturi effect flushing system positioned proximate to the bottom of the housing. The housing includes a perimeter and at least one intake aperture positioned in the perimeter to accept the wastewater. The filter is shaped to substantially restrict flow of particles into the filter and to the discharge apparatus. The discharge apparatus is in fluid communication with the wastewater in the tank and includes a discharge path to position to transport filtered wastewater outside of the tank. The venturi effect system is in fluid communication with the housing and the tank to return the particles restricted by the filter to the tank.
