Oily Water Separators

Separator Spares & Equipment, LLC offers a wide range of oily water separators (OWS) from leading manufacturers worldwide. We provide the suitable capacity and systems for every maritime installation.  Whether your system preference is a coalescing oily water separator or a centrifugal oily water separator, we provide a solution to meet your bilge oily water needs.

Bilge Water Separators

As regulations become more stringent and enforcement increases, everyone, including owners, designers, builders and operators of ships are becoming aware that the oily water separator (OWS) is a serious design specification, operating consideration, and a key personal responsibility.

Do you need a marine oily water separator?

Separator Spares & Equipment is committed to providing solutions for these needs. We provide equipment, consumables, spare parts, and/or services for coalescing filter oily water separators, centrifugal oily water separators, and oily content monitors. Failure is not an option. We are your link to IMO MEPC 107(49) compliance.

What is oily bilge water?
bilge-water-separatorOily bilge water is a mixture of water, oily fluids, lubricants, grease, cleaning fluids, and other wastes that accumulate in the lowest part of a marine vessel from a variety of sources, including engines (and other parts of the propulsion system), piping, and other mechanical and operational sources found throughout the machinery space of a vessel.

The economic justification for a oily bilge treatment system (oil water separator) is to reduce the volume of oily bilge water that must be stored aboard the vessel. For marine vessels <400 GT, the assumption is that these vessels make frequent port calls and, therefore, can store oily ballast water to be pumped ashore for treatment and disposal.

How oil gets into bilge water?

Oil can enter the bilge through several different ways. An oil can leak from onboard engines, gears, generators, hydraulic systems, and other oily equipment. This is often due to maintenance, wear and tear, imperfect seals, or system malfunctions. Accidental spills during the operation, maintenance, or refueling of ship machinery. Detergents used to clean the engine room and other areas of the vessel can pick up oil. Sea or rainwater entering the ship can bring oil from contaminated seas.

Responsible management of bilge water is essential for alleviating environmental impacts. It involves preventing illegal discharges to ensure bilge water is treated appropriately onboard before discharge or disposed of at dedicated facilities onshore.

What is oily water separator?

what-is-oily-water-separatorBilge separators, also known as oily water separators (OWS), are onboard treatment systems designed to remove the oil from vessel bilgewater prior to its discharge overboard.

Under MARPOL, all ships over 400 gross tons (GT) must have equipment installed onboard that limits the discharge of oil into the oceans to 15 ppm when a vessel is en route. All vessels over 400 GT must also have an oil content monitor (OCM), including a bilge alarm, integrated into the piping system to detect whether the treated bilge water being discharged from the oily bilge separator meets the discharge requirements.

Canada has bilge discharge requirements that are more strict than the international 15 ppm standard. The Canadian Regulations for the Prevention of Pollution from Ships and for Dangerous Chemicals requires 5 ppm bilge alarms on the Great Lakes.

Separator Spares & Equipment is your trusted source for IMO MEPC 107(49) compliance, we offer a broad range of marine oil water separators expertly designed to surpass all your bilge water treatment needs.

How does an oil in water monitor work?

Oil-in-water-monitor-workOil-in-water monitors or oil-in-water analysers can be used to detect and measure oil content in water. This can be known as the oil content monitor (OCM) on a maritime vessel. An oil-in-water monitor can use a range of measurement technologies to suit different applications. These include Scattered Light, Microscopy, Fluorescence, and Ultrasonics.

On maritime vessels, the oil content monitor (OCM) is fitted to the marine oily water separator and is responsible for ensuring that any oil in the water over 15 PPM is alarmed and prevented from being discharged into the sea, ocean, or river.

These oil content meters work using a light scattering measurement principle. The sample is passed through an optical cell, and the light scatter algorithms calculate the level of oil content measured by PPM (parts per million). 

Separator Spares & Equipment provides oil content monitors designed to meet and exceed the requirements for IMO MEPC 107(49) regulations. Additionally, these monitors can meet the clean water approvals of DNV-GL, US Coast Guard, CCS, Russian Register, and Transport Canada.
