- In detail
The membrane bioreactor (MBR) is a leading edge technology currently being used in countries around the world. Combining conventional activated sludge treatment with low pressure membrane filtration, the MBR proven to be a techno-commercially viable and efficient method of producing reclaimed water from municipal waste water.
The Membrane Bioreactor Process
An MBR substitutes the secondary clarifier with ultra-filtration or micro-filtration membrane modules. Unlike the clarifier, the membrane is a physical barrier that can capture the biomass for recirculation inside the bioreactor.
The MBR offers following benefits over the conventional activated sludge process:
* Smaller space requirements (almost 1/4th of ASP)
* Better solids removal (elimination of sludge bulking)
* Disinfection
* Increased volumetric loading
* Production of less sludge due to high sludge age
* High SRT which allows the development of slow-growing microorganisms such as nitrifying bacteria.
* Retention of high molecular weight soluble compounds that improve biodegradation.
