ABSTRACT:
Disclosed is an apparatus and method for the continuous biological treatment of ship bilge water contaminated with petroleum and biodegradable materials. The apparatus includes a pumping system attached directly to the bilge or to an oil-water phase separator, for removing the biodegradable material(s) contained in the bilge waste aqueous phase, which is integrated with a means for microbiologically treating the contaminated bilge water. The means for microbiologically treating the contaminated bilge water preferably includes petroleum- and hazardous-degrading microorganisms. In operation, a phase separator system on the ship separates the free-product phase from the contaminated bilge water. The separated free-product is removed for off-site disposal. Contaminated bilge water is fed into the microbiological treatment system for further treatment with eventual discharge overboard or recirculation into the contaminated bilge area.
