ABSTRACT:
A bilge water filtration system for removing petroleum-based liquid contaminants from the bilge water as it is being pumped from the bilge to a bilge water discharge outlet in the hull of a marine vessel, such as a boat or yacht. The filtration system employs filtration media enclosed in a modular unit equipped with a fill tube, such that media can be readily installed in the system, and then later removed to allow for subsequent destruction or recycling of the contaminants trapped by the media. The filtration system of this invention is adapted to be installed in-line with an existing bilge pumping system on boats and yachts of practically any size, and without requiring special modifications to the pumping system. In addition, the filtration system does not impede the operation of the bilge pumping system, but allows the flow bilge water to flow from the boat's bilge at conventional flow rates and with a minimal pressure drop caused by the filtration system.
