Principle

The marine oily water separator assembly consists of the separator body, special pump, electrical control box, 15ppm bilge water alarm device, suction filter assembly, and other pipelines, valves, and accessories, and it operates by using a three-stage oil filtering method.

The bilge water tank of the ship is equipped with a liquid level controller, which automatically controls the bilge water pump according to the water level. The bilge water is pumped into the first-stage oil filtering chamber of the separator, and the floating oil in the bilge water is separated from the water by utilizing the specific gravity difference between oil and water.

The coalescer in the second-stage oil filtering chamber coalesces and coarsens the fine oil particles in the bilge water to make them separate and float to the water surface for separation. The bilge water that meets the discharge standard after the second-stage treatment is directly discharged overboard.

If the bilge water after the second-stage treatment still fails to meet the discharge standard, the third-stage emulsified oil separation device will be automatically activated. The emulsified oil is separated into oil and water by physical methods to make the discharged bilge water meet the discharge standard and be discharged overboard. The separated dirty oil accumulates at the top of the oil filtering chamber. When the accumulated dirty oil reaches a certain amount, it can be automatically discharged to the dirty oil tank. The operation of the separator is fully monitored by the 15ppm alarm device to realize the switching of filtering levels and the automatic control of water discharge overboard or to the bilge.
