Membrane bioreactor (MBR) is now widely used for municipal (example. residential wastewater treatment) and industrial wastewater treatment, attributed to MBR process can produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for urban irrigation.
Recent technical innovation and significant membrane cost reduction have enabled MBRs to become an established process option to treat waste water. It it possible to operate MBR process at higher mixed liquor suspended solids concentrations compared to conventional settlement separation systems, thus reducing the reactor volume to achieve the same loading rate.
Other advantage of MBRs over conventional processes include:
- Smaller footprint
- Easy retrofit and upgrade of old wastewater treatment plants
- Superior effluent quality
- Lower lifecycle cost
