Principle

The device adopts the combination of 1st stage, cone plate gravity and coalesce separation; 2nd stage, membrane permeation in order to make the treated bilge water to reach the requirements of discharge standard of the resolution of IMO MEPC.107 (49).

The liquid coming out of Piston pump is adsorbed and filtered by the 2nd stage fiber filter to reach the discharge standard.

System flow
The bilge oily water comes into the 1st coalescer through Seawater initial filter and bottom valve, floating ball non-returned valve. There is an oil chamber in the tope of separator. Most of the oil in the bilge oily water floats to the surface of chamber because of the effects of small gravities. The tiny oil drops gather and coalesce in the cone wave plate which is made of hydrophilic and oil-left materials and floats in the main and then adverse current.

When the oil accumulates to interface level in the top chamber of the 1st coalescer, manual oil drainage is required. It resets automatically after the oil is discharged and it again starts to treat the oily bilge water.

The effluent already treated by the 1st coalescer comes into the 2nd filter and is treated again, then is discharged to overboard.
Then be discharged through sea valve finally.

As for the first operation, the containers and pipes are to be filled with water. When the water comes to a valve and flows out, this valve is to be shut. When the water comes to the air cock that means the water is filled fully.

 Oil content meter, i.e.15ppm Bilge Alarm; Refer to the instruction book of it.

Caution: This device uses high voltage power source and may cause the imminent hazardous injury caused by electric shock. The door of electric control box should not be opened at presumptuously. When doing electrical repair, make sure the power is cut off and the repair is to be done by professionals.
