A system for extracting free oil from industrial processing fluids contains a solids retention cartridge having a plurality of vertically oriented polymeric elements therein. The cartridge fluidly communicates with a retention chamber, wherein the retention chamber provides a predetermined residence time based on fluid flow as established by inlet and outlet pressure and also as established by valved fluid exit orifices. An aggregation chamber fluidly communicates with the retention chamber and provides an area for aggregation of a low density fluid such as oil for example. The low density fluid is then decanted from a decant chamber. The purified bulk fluid is drained from the retention chamber through an associated return chamber. The average cross-sectional area of the aggregation chamber is less than the average cross-sectional area of the retention chamber thereby enhancing the aggregation of a lower density fluid such as oil, prior to decant.
