ABSTRACT:
A system for extracting solids and free or "tramp" oil from an industrial machining fluid comprises a pressurized tank having a plurality of horizontally orientated polymeric elements therein past which fluid is free to flow without obstruction. Free oil is removed from the machining fluid through oleophilic attraction between the free oil and the surface of the polymeric elements when the tank is filled with fluid. The free oil and solids are removed from the machining fluid in a gravity separation chamber.
