ABSTRACT:
A system for controlling effluent discharge having an inlet for passing wastewater, a filter connected to the inlet for removing solids from the wastewater, a filtered water retaining tank connected to the outlet of the filter for accumulating a portion of the water passed from the filter, a filtered water outlet connected to the outlet of the filter so as to pass filtered water exterior of the system, and a controller connected to the filtered water retaining tank so as to selectively pass a flow of the accumulated water into the filter. The filter includes a first body portion connected to the inlet, a second body portion connected to the first body portion, a filter screen disposed in the second body portion between the first body portion and the outlet and having a plurality of openings therein, and a particulate filter material filling an area between the second body portion and the filter screen. The particulate filter material extends into the first body portion so as to filter wastewater passing therethrough.
