The right system for cruise vessels, navy ships and mega yachts

SMT - Sewage Membrane Treatment technology

- Meeting future standards 

The SMT-Process is a bioreactor with high biomass concentration. Submerged membrane filtration guarantees a pure effluent without any suspended solids and without the requirement of disinfection.

The SMT process permits both black and grey wastewater as well as galley wastewater to be treated in a single reactor system. The effluent levels are better than the requirements of the International Maritime Organisation (MARPOL, Annex IV) and both the future
standards MEPC.159(55) and the USCG/Alaska-Rules.

Advantages at a glance
⇒ Compact, packaged system
⇒ Highest effluent quality
⇒ For black, grey as well as galley wastewater
⇒ No disinfection necessary
⇒ High sludge age leading to highly effective BOD₅ and nitrogen degradation
⇒ Extremely low excess sludge production
⇒ Zero suspended solids in effluent
⇒ Safe for crew and ship / No chemicals required
⇒ Very low energy consumption
⇒ Fully automatic, with low maintenance and operating costs
⇒ No odour emissions thanks to effective odour control
⇒ Stable cleaning efficiency, even with varying inflow conditions
⇒ Fulfilling IMO (MARPOL, Annex IV, MEPC.159(55) and USCG/Alaska-Rules).
⇒ The right system for cruise vessels, navy ships and mega yachts
