ABSTRACT:
There is disclosed a system for separating oil and other immiscible organic materials from a liquid body or from a mixture with an aqueous medium. The system includes the use of a plurality of microporous hollow fibers which may be arranged in any number of arrangements such as bundles, intersecting arrangements, divergent patters or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communication with a pressure source in order to draw or force the contaminant into contact by the shell side of the fibers and through the micropores thereof. Discrete phase separation from a mixture in substantially pure form, i.e. no free phase contamination is achievable. This system provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments.
