Membrane Bio-Reactor (MBR) is a new wastewater treatment technology which combines membrane separation technology with the activated sludge process. It is a modern and efficient system, which can meet the growing demand of industrial and municipal sewage treatment.
Membrane Bio-Reactor
MBR module
- High water flux
- Good mechanical strength
- High fouling resistance and oxidation resistance
- Effective recovery capability of cleaning flux
- Good hydrophilicity
- Good separation performance
