Abstract: A wastewater solids strainer apparatus provides a tank-type container housing member having an interior cavity having an upper, solids separation and gravitation chamber and an underlying, lower, semi-solid material collecting sump chamber arranged to collect heavier-than-water solids and semi-solids settling by gravity from a volume of water maintained in the housing, a solids screen for collecting solid particles entering the housing through an inlet, and a housing outlet arranged to discharge wastewater from only the top portion of the volume of wastewater in the housing.

Abstract: A grease skimming and removal apparatus for use with grease trap settling tank apparatus provides a vertically elongated, vertically extending tower housing on the top wall of a grease trap tank and provides a power driven, vertically elongated, vertically extending rotating skimmer belt loop arranged to skim and transport grease and oils from wastewater contained in the grease trap tank to a vertically-elevated position above the top wall of the settling tank for gravity discharged therefrom and into a collection vessel releasably secured to the tower housing above the top wall of the grease trap tank.
