Abstract

A bilge water filter having an elongate tubular housing defining a bilge water outlet and adapted to receive a filter and filter support assembly which is secured in sealed relation therewith by manual retainer elements. The filter and filter support assembly defines an inlet through which is caused to flow bilge water of a marine vessel which may contaminated by oil and other petroleum products. The filter and filter support assembly incorporates an elongate, tubular perforate filter support element about which is positioned and secured a generally cylindrical closed end body of a thick filter media in the form of meltblown polypropylene (polyolefin hydrocarbon). The filter assemblies may be incorporated in valve controlled banks and may be controlled by valve settings to utilize the filters independently, sequentially or together to accomplish separation of oil from the bilge water to thus insure an overboard discharge of oil free bilge water.
