An evolution in waste water treatment

  • No cleaning of membranes
  • No chemicals
  • 5 year guarantee
  • Low maintenance
  • No foaming problems
  • Low energy consumption

Permanent Air Filters

As an example, large cruise ships may change as many as 3000 disposable filters two or more times a year; calculated over 12 years equals 72000 or more filters need to be bought, transported, stored and disposed of – contributing to environmental pollution. NWCA filters are guaranteed for the same 12 year period, they are bought once and are never replaced.

Waste Water Treatment

This diagram of the FMD/Hamann Consulting treatment technology shows wastewater in a tank being recirculated over a set of gills (membranes) via a pump and returning to the tank by gravity. Each gill consists of a vertical planar pair with the effluent passing down between them. Because the gills are suspended in the open air (as opposed to submerged) there is no limitation to the available oxygen for biomass growing on the gills. This technique is fundamentally different to other wastewater treatment philosophies within the marine industry, where typically oxygen is forced into the nutrient rich waste water to keep the biomass aerobic.
