Bilge water/ Oil separator BISEP 19
Introduction
Oil-contaminated bilge water, if discharged,
is likely to pollute the surface waters. This pol-
lution may be prevented by installing a Vetus
bilge water / oil separator in the discharge
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 con-
sists 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 vol-
ume of 8000 liters of water. Due to its high ca-
pacity, the filterelement therefore rarely needs
to be replaced. The filter housing has a trans-
parent 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 en-
sure optimum separation of water and oil. The
Vetus EBP30 model, for instance, is a suitable
pump for this purpose. In planning the stand-
ard setup (see ‘Installation Examples’, Figs.1
and 2 on page 18), this capacity should be
taken into consideration.
The capacity may be increased by connecting
two separators parallel to each other (see ‘In-
stallation Examples’, Fig.2).
Note: Please remember that the bilge water /
oil separator in the discharge pipe increases
the resistance!
Installation
• Install the bilge water / oil separator in an eas-
ily recognizable position, making sure that
the separator is always above water level and
high enough to prevent the bilge water from
returning and to avoid a siphoning effect.
Sailboats present an additional challenge if
they are sailed under a certain angle of heel.
• Attach the separator to a vertical bulkhead.
• For details concerning the primary dimen-
sions please see page 17.
