Abstract
An oil/grease separation apparatus includes a chamber for receiving a liquid flow containing water, oil/grease and gross solids. An inlet section is separated from a downstream section by a weir, so that a higher static water level is maintained in the inlet section than the downstream section, to facilitate one-way passage of oil/grease from the inlet section to the downstream section. A grinder/pump has an input port in a lower portion of the inlet section. The inlet section has an inlet port, a strainer separating the inlet port and the top of the weir to inhibit passage by solids to the downstream section, and a bottom which slopes downwardly toward the input port of the grinder/pump. An oil/grease separator located in the downstream section removes oil/grease from water held in the downstream section. The gross solids entering the chamber settle in the inlet section for periodic removal with some water by the grinder/pump, oil/grease and water entering the chamber pass to the downstream section where the oil/grease is removed from the water, and the residual water exits the chamber through the outlet section.
