Detect clean drains and economise your oil-water separation

the bilge holding tank for further treatment by the
oily water separator.
Based on the IMO guidelines for ‘Integrated bilge
water treatment systems“ (IMO MEPC.1/Circ.642),
RWO has developed the BilgeEconomiser.
The BilgeEconomiser allows ship operators to dis-
charge so called ‘clean drains’ overboard without any
further treatment.
As a consequence the bilge water volume handled
by the oily water separator is much smaller, which
reduces not only operating cost significantly.
Your advantages
Increased cargo capacity due to smaller
bilge holding tank
Fewer operations of OWS required
(not allowed in certain areas/ports)
Smaller oily water separator (reduced capex)
Increased maintenance intervals and
reduced labour cost
