Oil Water Separation System

1. Oil Water Separation System Application

This device can be used to treat the oily bilge water in order to make it reach the requirements of IMO.MEPC.107 (49) resolution, which is also called 15ppm bilge separator. It contains type approved 15ppm bilge water separator, 15ppm bilge alarm and Automatic shut down device.

2. Oil Water Separation System Principle

The device adopts the combination of 1st stage cone plate gravity and coalesce separator; 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 separator, inside it is a vacuum negative pressure stage by the suction of the feeding pump, 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.

3. Connection of Electric Box about Oil Water Separation System

Power source 380V/440V, 3Ф, 50HZ/60HZ is connected into electric control box; Bilge level probe, refer to electric draw, when the product leaves from the factory, the external contact points JYB3 ＃15, ＃5 or ＃6 of the liquid level relay which is used to detect the bilge water level are short connected. If bilge level probe needed to be linked, the short connected copper wire should be removed.
Warning: The operator should skill a basic technology and be familiar with the instruction. Also he should master the operation control and know clearly the maintenance regulations.

4. Connection of The Pipes about Oil Water Separation System

The bilge suction, effluent discharge, back flushing water inlet, and Return to bilge interface, oil outlet. should be fitted by the shipyard.
