The new HAMANN plant HL Cont Plus 02 Slim is treating black and grey waters on yachts or ships in accordance with regulation MEPC159(55) issued by the International Maritime Organisation IMO. This regulation reduces since 2010 the boundary value of wastewater emitted into sea.
The fully automated system works on the principle of flotation, a purely physical process not needing any chemicals or additives. In a flotation tank suspended solids are separated from the waste water and transferred into a sludge tank. Coli bacteria and other germs in the remaining clear wastewater are disinfected by UV radiation. The ZUWA COMBISTAR finally removes the clarified, germ free liquid from the vessel with a flow rate of 30 litres per minute and a pressure of 5 bars.
