Introduction
Oil-contaminated bilge water, if discharged,
is likely to pollute the surface waters. This
pollution may be prevented by installing a
Vetus bilge water / oil separator in the dis-
charge pipe of the bilge pump. The filter
element in the bilge water / oil separator will
separate oils and fats from the bilge water
before it is pumped overboard.
The filter element consists of a coherent
mass of surface-treated fibres. This filter
material absorbs and retains up to 95% of
the oils, fats and emulsions in the water. In
addition, heavy metals are isolated as well.
The oil content of heavily contaminated
water varies between 100 and 200mg/l (100
to 200 ppm). The filter element can process
water containing contaminations of up to
300 mg/l.
The filter element has a capacity that
enables it to absorb approximately 320 g of
oil. At an average oil contamination level of
40mg/l, the filter element can therefore
process a total volume of 8000 liters of

11.0304
water. Due to its high capacity, the filterele-
ment therefore rarely needs to be replaced.
The filter housing has a transparent cover to
allow inspection of the filter element without
opening the separator.
Capacity
Preferably a bilge pump with a capacity of
approximately 20l/min should be used to
ensure optimum separation of water and oil.
The Vetus EBP30 model, for instance, is a
suitable pump for this purpose. In planning
the standard setup (see 'Installation
Examples', Figs.1 and 2 on page 26), this
capacity should be taken into considera-
tion. The capacity may be increased by
connecting two separators parallel to each
other (see 'Installation Examples', Fig.2).
Note: Please remember that the bilge water
/ oil separator in the discharge pipe increas-
es the resistance!
