Having undertaken extensive tests and trials to iron out
some initial installation and commissioning difficulties, Westfalia Separator's
new WSC oily water separator has been launched and gained IMO approval to
MARPOL.
The system, already installed on cruiseships Royal Princess, Oriana, and Aurora, uses the latest in separation
technology to remove oil and waste material down to well below the limit of
15ppm, making it environmentally safe for discharge overboard, without the need
for filtration.
It works by sucking up the oily water through a pre‑heater
into the centrifugal separator. The water phase is separated from the oil and
then passed through an oil content meter to check the concentration of the
remaining oil. if this is above the accepted limit of 15ppm, then it's whizzed
around for further treatment. The system adapts automatically to the
concentration of oil in the water by changing the pump speed via a frequency
converter.
Compact and designed for continuous unmanned operation,
the 15000 litre/h capacity WSC 5 and 6000 litre/h capacity WSC 25 systems are
each supplied with all the necessary components: feed pump, pre‑heater, a
control and monitoring system, and a small sludge tank to hold separated
impurities.

This is a great idea to use the centrifugal separator aboard cruise lines and other ships, so that the water can have waste and oil removed before release back into the sea. I am glad that these companies have become environmentally responsible in the wake of disasters like the Exxon spill among others. This small action can make a big difference.
