Bilge Oil Water Separator
1. Bilge Oil Water Separator General
The device adopts the combination of 1st stage, cone plate gravity and coalesce separation; 2nd stage, fiber filter and 3rd 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).
Bilge water comes into the 1st stage coalescer separator because of the suction of the Feeding pump, that is in a vacuum negative pressure, and it effectively prevents the problem that the bilge water is difficult to be separated because of the emulsion caused by feed pump under pressure.
The liquid coming out of Feeding pump is adsorbed and filtered by the 2nd stage fiber filter, and then goes into the 3rd stage membrane to reach the discharge standard.
There is a 15ppm bilge alarm in the ship cabin to measure the oil content of effluent. If it finds that the oil content of effluent is in an excess of limit, the oil content meter can make order to switch turn it into the 3rd stage, membrane treatment process.
The oil content meter will give an alarm if finds the oil content of effluent is above limit, and the unqualified water pneumatic three-way valve VS6 is opened automatically, so that the unqualified water is return to bilge, not to the overboard.
2. Connection of The Pipes about Bilge Oil Water Separator
The bilge suction, effluent discharge, back flushing water inlet, and Return to bilge interface, oil outlet. should be fitted by the shipyard.
