Membrane Bioreactors:
Main Features & Advantages
- Complete removal of suspended solids of the water
- Long lifetime of the membranes with fully automatic operation and back flushing.
- Avoids presence of chemicals during disinfection stage
- No odor emissions due to biological process
- Excellent quality effluent for the compliance with stricter regulations
- Customizable design for larger crew requirements
While treating both black and grey water together, the submerged membranes filtration system delivers the highest quality effluent, exceeding the required limits of the current IMO MEPC 159(55) and IMO MEPC 227(64) for an eco-friendlier operation of the vessel.
MBR are a worthy option for large crew vessels, due to its compact size, and also to assure an excellent effluent quality in special areas.
