Product Introduction
MBR membrane bioreactorMBR is a new type of wastewater treatment system that combines biological treatment technology and membrane separation technology. It mainly consists of two technical units: bioreactor and membrane module. Compared with the traditional activated sludge process, MBR replaces the secondary sedimentation tank in the traditional activated sludge process with membrane separation.

technical advantage
Compact structure and small footprint
Compared to traditional activated sludge water treatment processes, MBR processes can save more than half of the land area. Especially the integrated MBR achieves both biodegradation and sludge water separation in one reactor, with a high degree of system integration and automation.
Good treatment effect, excellent and stable effluent quality
MBR treatment of urban sewage has no suspended solids in the effluent, and the water quality is superior to traditional biological treatment processes, making it suitable for reuse as reclaimed water. And MBR eliminates the reliance on gravity settling of sludge for sludge water separation, solving the problems of sludge water separation and water quality deterioration caused by activated sludge expansion in the secondary sedimentation tank.
High volumetric load and strong resistance to load impact
MBR treatment of urban sewage has no suspended solids in the effluent, and the water quality is superior to traditional biological treatment processes, making it suitable for reuse as reclaimed water. And MBR eliminates the reliance on gravity settling of sludge for sludge water separation, solving the problems of sludge water separation and water quality deterioration caused by activated sludge expansion in the secondary sedimentation tank.
Low residual sludge volume and low treatment cost
At present, the treatment and disposal of surplus sludge has become one of the limiting factors for the normal operation of sewage treatment plants. Therefore, it is necessary and crucial to reduce the amount of sludge generated from the source. The sludge retention time in MBR system is long, and the remaining sludge production is low.
Enhance the denitrification efficiency of the system
The long sludge retention time in MBR is beneficial for the growth of slow proliferating bacteria, such as nitrifying bacteria and other microorganisms. The sludge flocs in MBR are relatively small, and smaller flocs have a larger circumference/area ratio, resulting in lower oxygen mass transfer resistance. In addition, the sludge concentration in MBR is high, which makes it easy to form a surface aerobic and internal anoxic state in the sludge flocs. Therefore, nitrification and denitrification can be achieved in the same reactor, enabling MBR to have good denitrification effect while removing COD.
