The waste water treatment is an essential process. It is especially important for industries for waste discharge and water reuses and also important for muncipals. | The waste water treatment is an essential process.

While there are different processes which are used for waste water treatment, two major processes are the conventional process and the membrane bioreactor process (MBR). The conventional process uses action of microorganisms to breakdown chemical components of effluent system. But the MBR need to be used due to growing populations. | While there are different processes which are used for waste water treatment, two major processes are the conventional process and the membrane bioreactor process (MBR).

- | + | The MBR was developed 40 years ago and have been used commercially for almost 30 years in Japan. Apart for muncipal and industrial purposes, the MBR is also for (1)Filtration (2) Ultrafiltration (3) Microfiltration (4) Removal of salts (5) Reverse Osmosis (6) Nanofiltration (7) Irrigation. | |
This is process uses membrane coupled aerobic bioreactors with the activated sludged system with an integrated membrane, eliminating the need for a final clarifier. There is also something known as membrane fouling which in other words is the membrane performance. This performance is dependent on the effluent quality of the biofilm reactor and it varies with the hydraulic retention time (it's the time the wastewater takes to pass through the system). Due to the increase in population, MBR must be used. Apart from this there are several other advantages MBR has over the conventional process. | This is process uses membrane coupled aerobic bioreactors with the activated sludged system with an integrated membrane, eliminating the need for a final clarifier.
