A casing having an inlet which receives oil-based contaminated bilge water is mounted on a boat or ship in aligning a generally U-configured pipe vertically, in which first and second open ends of the pipe are overlaid with one of a gravel or charcoal coarse material restrictive to the flow of oil-based contaminants, and with the second open pipe end coupled to the casing outlet, such that with a plurality of filter pads floating atop the overlying layer adapted to absorb oil-based contaminants, a continuous absorption of the contaminants occur as the bilge water circulates through the casing and is allowed to dwell therein while the filter pads absorb the oil-based contaminants floating atop the inputted bilge water.
