Marine 15PPM Bilge Water Separator

Oil Water Separator  In Ship – 15PPM Bilge Water Separator

The 15PPM Bilge Water Separator is available in nine different types, offering a capacity range from 0.25m3/h to 5.00 m3/h. The compact DY-0.25 model is suitable for installation on smaller ships with a displacement tonnage (DWT) of less than 1000, while the larger DY-5.00 model can be utilized on ships exceeding 300,000 DWT. These oil water separators not only find their application in marine vessels but can also be effectively employed in industrial and petroleum sectors, showcasing their versatility and wide-ranging utility.

With its adherence to stringent environmental standards and ability to efficiently treat bilge water, the 15PPM Bilge Water Separator stands as a crucial component in safeguarding marine ecosystems and complying with regulatory requirements. Its technological advancements and flexibility make it a reliable choice for diverse marine operations and other industries requiring effective oil-water separation capabilities.

How Does A Marine Bilge Water Separator Work?

A marine bilge water separator operates through a series of stages to effectively separate oil from the bilge water. Here’s a general overview of how it works:

• Coalescing Stage: The first stage of the separator unit utilizes coalescing media, which are typically hydrophobic materials designed to attract and coagulate oil droplets. The bilge water containing oil passes through this media, and the oil droplets adhere to the media, gradually forming larger oil droplets.
• Sediment Filtration Stage: After the coalescing stage, the partially treated water flows into the sediment filtration stage. This stage typically consists of filters or filter media that capture solid particles and any remaining oil droplets that have not been coalesced in the previous stage. The filters help remove fine particles and further refine the water quality.
• Emulsion Removal Stage: The final stage of the bilge water separator system is focused on removing any remaining emulsified oil from the water. Emulsified oil refers to oil droplets that are finely dispersed and mixed within the water, forming an emulsion. This stage often employs specialized media or chemical agents designed to break down the emulsion and facilitate the separation of oil from water.

Oily Water Separator Discharge Regulations MARPOL

Under MARPOL (International Convention for the Prevention of Pollution from Ships), there are specific regulations regarding the discharge of oily water from ships, including the use of oily water separators. The regulations aim to prevent pollution and protect the marine environment. The key regulations related to oily water separator discharge are found in Annex I of MARPOL. Here are some important points:

• General Prohibition: According to MARPOL Annex I, it is prohibited to discharge any oil or oily mixtures into the sea from ships, except under certain conditions specified in the regulations.
• Oily Water Separator: Ships are required to be equipped with an oily water separator (OWS) to separate oil from oily water mixtures on board. The OWS is designed to remove oil content from the water, allowing for the discharge of “clean” or treated water.
• Discharge Standards: The discharge of oily water from ships is subject to strict standards. Ships must ensure that the oil content in the discharged water is below the allowed limit. As per MARPOL Annex I, the maximum oil content in the discharged water should not exceed 15 parts per million (ppm).
• Bilge Water Management: Ships are required to implement proper bilge water management practices. This includes using the OWS to treat the bilge water and separate the oil before discharge. In some cases, ships may be allowed to discharge bilge water that has not been treated by the OWS, but only if the oil content does not exceed 15 ppm and other specific criteria are met.
• Record-keeping: Ships are obligated to maintain accurate records of all oily water discharges, including the amount and location of discharge, as well as OWS operation and maintenance records.
