ABSTRACT:
An apparatus for continually separating water and water souble substances and hydrocarbons and/or halogenated hydrocarbons from contaminated water includes first and second separator modules (12,14) for separating a water and water soluble substance permeate and pure hydrocarbon and halogenated hydrocarbon permeate from a contaminated water retentate. A fluid conducting circuit: (a) conducts water contaminated with hydrocarbons and/or halogenated hydrocarbons to the first separator module (12), (b) conducts a portion of the first contaminated retentate and a portion of a second contaminated retentate back to the first separator module (12) (c) and conducts another portion of the first contaminated retentate and another portion of the second contaminated retentate to the second separator module (14). The invention provides a method of utilizing the apparatus for continuously separating water and hydrocarbons and/or halogenated hydrocarbons from contaminated water.
