A complete pollution-prevention solution for bilge water, the PetroLiminator is a U.S. Coast Guard (USCG) and International Maritime Organization (IMO) approved oily water separator (OWS) that easily handles phase-separated oil, emulsified oil and other contaminants. Properly used, the system takes suction directly from the ship's bilge or oily water collection tank and reduces the total petroleum hydrocarbons to typical concentrations of less than 5 ppm. Emulsified oil is readily processed by the system, whether caused by detergents and/or the ship's mechanical systems.


Unlike conventional oil water separators, the PetroLiminator actually destroys oil and grease using naturally occurring bacteria. The PetroLiminator is an automated bio-mechanical system which requires low maintenance and has been employed on a variety of ship platforms (i.e., ferries, ore carriers, tankers, oil exploration vessels, military vessels, etc.) since 2000. Compelling reasons that more and more ship owners are switching to this technology include: low operating costs, ease of use, green technology, little or no HAZMAT, industry validation and excellent reliability to mention a few.


The system is designed to work 24 hours a day, 7 days a week but can accommodate other schedules or instances as needed. Approved to process 3.8 gallons per minute, the PL630M system, for example, can easily process up to 20 cubic meters (5,400 gallons) per day.
