Membrane Bio-Reactor(MBR) system
design and construction
What are MBRs
The term 'membrane bioreactor' (MBR) is generally used to define wastewater treatment processes which integrate a-selective membrane e.g. microfiltration or ultrafiltration with a biological process to allow the process to function as desired. MBR processes can be operated at higher mixed liquor suspended solids (MLSS) concentrations and the sludge solids are completely retained in the bioreactor, thus reducing the reactor volume to achieve the same loading rate.
MBR Features
- Sludge solids are completely retained in the bioreactor compared to conventional settlement separation systems.
- Concentrated sludge cake. Functional system regardless the in-flow status. High operational reliability.
- Longer solids retention time (SRT) enhancing removal effectiveness.
- Stay ideally low food-microorganism ratio.
- Small footprint benefit for existing facility extension.
- Easy maintenance
