Ensolve - PetroLiminator Series
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 water. Properly used,
the system takes suction directly from the ship's bilge or oily water
collection tank and reduces the total petroleum hydrocarbons to less
than 15 parts per million. Emulsified oil is easily handled by the
system, whether caused by detergents and/or the ship's mechanical
systems.
This automated bio-mechanical system is safe, reliable and
requires low maintenance. Unlike conventional oil water separators, the
PetroLiminator actually destroys oil and grease using naturally
occurring bacteria. The technology used in the PetroLiminator has been
successfully used in hundreds of land-based applications since the
1970's. Now, the PetroLiminator has been improved and specially designed
for shipboard applications. EnSolve received a patent in 1998 for
shipboard use of the PetroLiminator.
The fully automated system is designed to work 24 hours a day, 7
days a week but can accommodate other schedules or instances when the
bilge water has been entirely processed. The PL-100 system can easily
process up to 5,000 gallons per week; the PL-300 can handle up to
10,500; and the PL-630 can easily process 20,000 gallons per week
because of their unique design.
PRODUCT FACT SHEET:
PetroLiminator PL 630M OWS.The PetroLiminator PL 630M is a (IMO) MEPC 107(49) approved Oily
Water Separator (OWS) that easily handles phase-separated oil, emulsified oil and water.The system processes oily bilge water and reduces petroleum hydrocarbon concentrations to less than 15 parts per million (ppm), typically 1 to 5 ppm. Emulsified oil is also easily handled by the system, whether caused by detergents and/or the ship’s operation. This automated bio-mechanical bilgewater treatment system is safe, reliable, and simple to use. Unlike conventional oil water separators,the PetroLiminator actually destroys oil and grease using naturally occurring microbes.The automated system is designed to work unattended 24 hours a day, 7 days a week but can accommodate practically any schedule, processing up to 5,400 gallons (20 m3) per day.
Cost Savings: Reduces offloading, maintenance, and operational costs associated with sludge, spent
flocculants, filters and/or bilgewater. Some clients have seen a reduction in operational costs of up to 10
times as compared to competitive OWS technologies.
Guaranteed Operating Costs: Ongoing operating and consumable item costs are minimal on the
PetroLiminator PL 630M system compared to competitors’ systems using replacement filters, chemicals
and other consumables. In fact, EnSolve Biosystems will guarantee the operating costs of the unit to
lock in your annual Bilge Water treatment costs for your vessels.
Green Technology: Little or no HAZMAT materials to dispose. The microbes in the PetroLiminator
consume oil and other organic wastes to produce safe end products.
Industry Proven: The PetroLiminator has been successfully employed on ships of many different
platforms since 2000, including cruise ships, ferries, product tankers, ore carriers, military vessels,
workboats, offshore oil rigs, etc. All systems installed are still in operation and no discharge violations
have been attributed to the PetroLiminator system.
Processing of Emulsified Oils: Chemical and mechanical emulsions are easily processed, including
many organic wastes such as anti-freeze, solvents, etc.
Seatrade Award winner in 2001 for the world’s first biomechanical
marine oily water separator.

PetroLiminator System Operation
The PetroLiminator consists of three distinct stages for removing oil and contaminants from Bilge Water.
STAGE 1 allows for initial separation and removal of pure oil.
STAGE 2 contains safe, non-pathogenic microorganisms that convert oil, grease, transmission fluid, gasoline, fuel, and other hydrocarbons into harmless end products.
STAGE 3 allows for removal of clean effluent.
Frequently Asked Questions
What cost savings can be realized?
This varies from ship to ship but typical operational savings range from 3 to 12 times less costs as compared to physical/chemical OWS systems.
Will the crew have to handle the microbes?
NO. Additionally, limited entry to the system is required. The microbes are harmless, nonpathogenic
microorganisms that are safe to handle.
Are any of the microbes, nutrients, or byproducts of the process harmful of considered hazardous material?
NO. The microbes and nutrients provided are safe to handle and use. The byproducts are negligible amounts of carbon dioxide and water.
How much labor does the system require?
The system typically takes less than 15 minutes per day to operate. The PetroLiminator does not generate large amounts of sludge and can be operated under normal conditions with minimal cleaning.
What happens to microbes from the system that are pumped overboard or spilled?
The microbes used in the system were isolated from natural sources and pose no hazard to
humans or the marine environments. Microbes that enter the bilge may even provide a small
benefit to the cleaning/treatment process.
