-14- REGENERABLE FLOW-THROUGH OIL/WATER SEPARATION APPARATUS Abstract Apparatus for separating oil from water employing a cylindrical, axially compressible, flow-through, oleophilic, hydrophobic reticular foam filter body covered peripherally with and bonded to a flow impervious flexible skin of resin impregnated fabric anchored at one end within a pressure vessel by a flow-through cap assembly sealing the adjacent end of the sleeve to the chamber wall.With the remainder of the sleeved filter body slidably retained and backed within such filter chamber, pressure applied intermittently to its opposite end compresses the filter body to squeeze oil accummulations therefrom. Cap means with one-way valve elements on such opposite end of the filter body permits flowof water through the filter body in one direction while obstructing reverse flowunder fluid back pressure introduced into the downstream end of the pressure vessel so as to compress the filter body axially. Back-pressure fluid also entering the narrow gap surrounding the sleeve and the pressure vessel wall helps prevent binding of the accordioning sleeve therein during compression cycles.
