Bauer BF Series Geared Motors Shipboard Water Treatment Systems
Ships used to have a large discharge pipe to dispose of everything that was no longer needed
on board. The pipe is still there, but now environmental awareness has been codified in new
Marine vessels generate four different types of wastewater which include: blackwater (toilets),
greywater (bathing, washing machines), kitchen wastewater (oil, grease, and food), and
bilge water (condensation water, oil, and fuel). The traditional wastewater treatment process
consisted of the biological treatment of the blackwater, followed by its discharge into the sea
with the greywater and kitchen water once they had all passed through a disinfection stage.
The bilge water then followed after passing through an oil separator.
Shipboard waste treatment can be challenging, especially because space is tight and
watercraft and wave motion does not make the task any easier. Today’s state-of-the-art
technology enables the combined treatment of blackwater, greywater and kitchen wastewater
together with degreased bilge water in a single reactor system.
Huber SE, located in Berching, Germany, builds machinery for water treatment plants and
supplies components for shipboard water treatment systems. For each shipboard water
treatment plant, HUBER supplies two perforated screen systems fitted with Bauer geared
motor drives. Bauer BF Series gear motors feature a hardened wear sleeve and spray ring at
the rotor seal which allows for reduced sump capacity, reliable lubrication and many years of
leak free performance.
The most recent wastewater system operates onboard an American cruise ship with a length
of 315 meters and a width of 36.8 meters, and it accepts everything that 2,850 passengers,
crew, ship chefs and the laundry have to dispose of.
