ABSTRACT:
The performance of mechanical skimmers for the removal of oil from water is enhanced through use of an oil-avid contacting member consisting of a non-woven mat of oleophilic fibers; the fiber surfaces having a film coating of a non-crosslinked rubber. A drum-type skimmer having the drum surfaces covered with such an oil-avid mat may be operated at very high rim speeds to obtain high rates of oil recovery with little water contamination. A process for coating the fiber surfaces with a rubber film is also disclosed.
