Wärtsilä Hamworthy Membrane BioReactor Systems

Wärtsilä Hamworthy MBR technology is based on biological degradation and membrane separation and allows for the treatment of grey and black water to satisfy the most stringent standards.

The process produces the highest quality discharge without requiring any addition or generation of chemicals that are hazardous to the environment or ship operation.

Effluent quality tests conducted by the US National Sanitary Foundation on Wärtsilä Hamworthy’s MBR produced results exceeding the most stringent future legislative pollutant standards envisaged. The technology also achieved outstanding performance in Alaska under the scrutiny of the local authority, USCG and USEPA studies over the past seasons.

We also supply smaller, more compact versions of our MBR systems. Wärtsilä Hamworthy miniMBR’s are ideal for use on smaller cruise and naval vessels, plus ferries with up to a 200 complement, as well as FPSOs and accommodation platforms.

    • Crown Princess
      Wärtsilä was contracted by Princess Cruises to retrofit its 113,000 GT cruise ship with 3 x Membrane BioReactor (MBR) plants. The ship holds 4,620 people on-board and was originally built in 2006. It sails mainly in US waters.

    • Queen Mary II
      At the time of her construction in 2003 by Chantiers de l'Atlantique, the Queen Mary II was the longest, widest and tallest passenger ship ever built, as well as the largest. To power this enormous vessel, four Wärtsilä 46 engines with a total output of 67.2 MW were chosen.
