Description
Membrane bioreactor, as we know,the MBR treatment technology is a biotechnology and membrane technology conbined with efficient biological treatment technology. Membrane bioreactor is a combination of an efficient membrane separation technologu and traditional sludge wastewater treatment technology. The application of hollow fiber membrane repaced the activated sludge in the secondary sedimentation tank.
Membrane Bioreactor (MBR) is a process that combines a membrane ultra filtration process and activated sludge process. (The MBR process is used in place of the secondary sedimentation tank and sand filter used for tertiary treatment in the conventional activated sludge process.) Hydro Blue Membrane Sewage Treatment Plant provides features such as space saving, easy operation and high quality treated water which is reusable. In addition, advanced treatment of nitrogen and phosphorus removal can be achieved by anoxic / aerobic treatment. According to customer requirements and site conditions, Hydro Blue offers drawing of MBR Plants to customers.

The MBR membrane bioreactor has two configurations:
1.Submerged/internal: In this, the membranes are absorbed in and essential for mbr membrane bioreactor.
2.External: In this, the membranes are a distinct unit process which requires an intermediate pumping stage.
Due to the recent cost reduction and technical innovations, MBR membrane bioreactor has become a process that is a well-established option for treating wastewater. This is the reason why MBR has become a popular option for reusing and treating municipal and industrial wastewaters as shown by the constant rising capacity and numbers. For reducing the footprints of activated sludge sewage treatment system membrane bioreactors are used. They remove a few of the liquid from the mixed liquor. This leaves behind a concentrated waste product that is treated afterward by the activated sludge process.
