Bilge Water Separation Processor

Bilge Water Separation Processor

1. Application of Bilge Water Separation Processor

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).
As shown in the enclosed drawing, 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.

3. Maintenance of Bilge Water Separation Processor

(1) The cone wave plate separator inside the 1st separator should be back flushed regularly. The method is to turn the "exchange switch" Q3 to the condition of “manual back flush”. At the same time, close the waste oil valve on the waste oil tank and open the backwash valve to let clean water go into the bottom from VS2 and go out from VS1 and to let water back to bilge. This process is to be done every 6 months and the time needed is about 15 minutes once time.

(2) As for the replacement of the filter core of the 2nd filter, if the pressure differences of the inlet and outlet of the 2nd filter are over 10m-H2O, which means the block is very serious and the device should be shut down and the liquid in the 2nd filter should be drained. Open the lid and take out the blocked filter core and replace it with a new one which is the same size as old one. At last, cover the lid. The core is to be replaced once a year averagely.
