Membrane Bio Reactor wastewater treatment system.
High-performance wastewater treatment for regulated marine environments.
Hamworthy's Membrane Bio Reactor (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’s Membrane Bio Reactor 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 Water & Waste mini-MBRs are ideal for use on smaller cruise and naval vessels, ferries with up to a 200 complement, as well as FPSOs and accommodation platforms.
Why operators choose Hamworthy MBR systems:
Designed to become more efficient over time:
In 2016, the flux rates improved to 50m3/day.
Increasing flux rates by 150% decreases membrane power consumption by up to 60%, as well as providing the ability to reduce the number of membranes required.
How the MBR system works:
External membrane technology:
Built as a complete treatment system.
