Abstract

An F.O.G. separation apparatus includes a tank for receiving a liquid effluent flow containing water, F.O.G., and gross solids. The tank has a chamber, an inlet in an inlet module, a downstream section and an outlet in an outlet module. The inlet module has a weir for the effluent downstream of a strainer to strain gross solids from the effluent. A pump upstream of the strainer pumps water and solids that do not pass through the strainer. The pump's rotatable vertical shaft has a motor at an upper and an impeller at the bottom. A pipe connected to the inlet module near the impeller conveys solids and water when the pump is activated and directs the solids and water to the outlet. F.O.G. and water entering the tank pass to the downstream section where the F.O.G. is removed from the water by a skimmer, and the residual water exist the tank through the outlet module.
