About MBRs home page
A membrane bioreactor (MBR) is a wastewater treatment process where a perm-selective membrane is integrated with a biological process – a suspended growth bioreactor.
A membrane bioreactor is essentially a version of the conventional activated sludge (CAS) system. Whereas the CAS process uses a secondary clarifier or settlement tank for solid/liquid separation, an MBR uses a membrane. This provides a number of advantages relating to process control and product water quality.
