<p>There is disclosed a system for separating oil and other immiscible contaminants from a liquid body containing the contaminants such as a water body. 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 patterns or in a mat-like arrangement or a combination of the foregoing. The hollow fibers are in communication with a source of pressure in order to force the contaminant via the pores into the fibers for subsequent storage in a suitable container. By incorporating acceptable means of density control, a substantial amount of the hollow fiber surface area may be exposed to the contaminant, thus increasing the extraction efficiency of the contaminant from the water body. The unit optionally may be self-contained. This system provides a substantial advantage over existing arrangements in that extraction efficiency is greatly enhanced in any number of environments. The system and methods are also useful in recovering crude oils, metals or other dissolved components, etc., from the aqueous phase.</p> |
