MBR is a kind of new technology for waste water treatment by combining membrane separation technique with activated sludge method.  It can be used for municipal sewage and industrial waste water treatment and substitute for secondary sedimentation tank in removing suspended particles, so as to increase nitrogen removal rate and organics degradation rate.


As a waste water treatment system features simple operation, high automation and modular design, it also has below advantages. 
1) Save 50% occupying area compared with traditional system.
2) Relative high MLSS value(<15g/L) and long residue time for sludge(<60days)
3) Stable producting water quality for different inlet water.
4) Less sludge residue reduces cost for sludge treatment .
5)  Low energy consumption, simple cleaning and low opreation cost

Technological process 

1) Because the high-efficiency soild-liquid sparation, It can efficiently remove the SS, colloidal material and dead microbe in the sewage, no need sedimentation tank, or filter device , nor other solid-liquid separation device.

2) The MBR can make the biomass in biological treatment unit maintain high concentration, thus highly improve the volume loading. Meaningwhlie, the high efficient membrane separation can shorten the HRT. The device is with a compact structure and small space occupation.

3)  MBR can filter out bacteria, part of the harmful material such as virus, it can obviously save dosing disinfection dosage, greatly improve the quality of the output water and raduce the operating cost and widen the scope of application of water .

4) Due to the strong interception function of MBR, it can keep the microbe in the reactor to avoid the loss of all kinds of microbe qroups, which is good for the qrowth of the bacteria(such as the nitrifying bacteria) at the same time , it can lengthen the residence time of diffcult degradable macromolecule organics to improve the decomposition so as to make the metabolic system process smoothly. The system has a strong impact resistance and wide suitability.

5) It can realize the completely separation of HRT and SRT. By the extended aeration, it can consume the otganics, it can theoretically achieve the effect of no excess sludge emissions, thus reduce the surplus sludge treatment costs significantly.

6) The unique mode of operation makes the membrane surface no blocking, and cleaning interval   time is long. The way to clean the membrane is easy, since the membrane module can be separately cleaned, thus, the maintenance is convennience and simple.

The module design make the machine flexible,it is easy to expand the volume.
