1m³per hour Marine Bilge Water Separator

1m³ Marine Bilge Water Separator

Bilge water separator is designed and manufactured according to  the IMO resolution MEPC.107(49), Guidelines and Specifications for Pollution Prevention Equipment for Machinery Space Bilges of Ships. This Equipment is used for the treatment of bilge water of various ships. The treated bilge water will be able to meet the standard specified by the IMO MEPC.107(49) Resolution and then may be discharged overboard.

Working Process

The separator adopts three-stage oil filtering method. Bilge water is pumped by the bilge water pump into the first-stage oil-filtering room, where the first-stage separation is performed using the specific gravity difference of oil and water and the floating oil is separated from the water through the method of gravity. After the first-stage separation, the bilge water still contains small oil particles of diameter ≥0.5μ(i.e. emulsified oil), which are coalesced together (thus become bigger) through the coalescer in the second-stage oil-filtering room, and then be separated and float to the surface. Bilge water satisfying the discharge standard through the second-stage treatment will be directly discharged overboard. If the bilge water contains too much emulsified oil, it still fails to meet the discharge standard after the second-stage treatment, then the third-stage dialysis apparatus will be put into operation automatically to enable the bilge water to meet the discharge standard. The separated dirty oil is collected in the top of oil-filtering room. When the collected dirty oil reaches certain amount, it will be automatically discharged to the dirty oil tank (for details see the system schematic diagram of the 15ppm bilge water separator).
