A system for extracting free oil from industrial processing fluids comprises a coalescing cartridge (10) having a plurality of vertically oriented polymeric elements (16) therein past which fluid is free to flow without obstruction thereby supplying fluid to a tank having a plurality of setting chambers (20 and 30). Free oil is removed from the processing fluid through oleophilic attraction between the free oil and the surface of the polymeric elements (16). Remaining free oil is further separated from the processing fluid through gravitational attraction (22, 34, 50, 70 and 80). A plurality of weirs and baffles (24 and 32) interposed between the settling chambers provide continuous return of purified processing fluid to the system. A plurality of solenoid actuated valves (54 and 86) provide periodic decanting of separated free oil. |
