Bilge oil Water Separator can treat the ship’s bilge water
containing various fuel oils, extremely dense residual residues,
and emulsion mixture configured with iron oxide and surfactant
effectively. The treated water meets the IMO MEPC.107(49)
resolution and can be discharged outboard directly without
environmental pollution.
This device can be used to treat 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.
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).
The bilge water comes into the 1st stage coalescer separator
because of the suction of the Ration 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 Ration 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.
