Abstract
An oil/grease separation apparatus includes an inlet section for receiving a liquid flow containing water, oil/grease and gross solids. The gross solids are separated from the liquid flow and collected in the inlet section. A water jet eductor is provided having a solids extraction port located in a lower portion of the inlet section. The water jet eductor is actuated by supplying pressurized water to create a suction to extract the accumulated solids from the inlet section. The extracted solids are directed to a separator outlet or to an alternate disposal system by suitable piping.
