MBR Integrated System

 The rural MBR integrated treatment technology integrates anaerobic, MBR and control room, overcomes the shortcomings of the traditional treatment process, such as long process, large area, complex operation and management.

     Compared with the traditional process, underground integrated equipment has the advantages of compact structure, beautiful appearance, small area, low operation cost, stable and reliable, high degree of automation, convenient operation and maintenance, high nitrogen removal efficiency and good water quality, high efficiency, high degree of automation. Equipment has a variety of standard specifications, but also customizes non-standard products in accordance with the actual needs of customers. 
   

 At the same time, MBR is one of the most advanced technology of sewage, is an efficient combination of membrane separation technology and biological treatment method, its main principle is to replace the activated sludge in the clarifier with two membrane separation technology for water separation. The working principle is to remove organic pollutants by microbial degradation, but because the film's excellent retention properties of activated sludge (MLSS) can be completely retained in the reactor, thus greatly enhanced the degradation of this organism. The dialysis effluent of the membrane is extracted by a low-pressure suction pump. This process not only effectively achieves the purpose of slurry separation, but also has the incomparable advantages of the traditional process of three stage sewage treatment:
 

•   Good water quality, high stability, the membrane filtration effluent makes the bioreactor obtain much higher biological concentration than the ordinary activated sludge method, greatly enhances the biodegradation load and the efficiency. At the same time, longer sludge retention time, which makes difficult-to-degrade organic decomposition bacteria and nitrifying bacteria and other slow-growing microorganisms, can be enriched in the reactor, especially for the removal of refractory organic matter and ammonia nitrogen to achieve the desired effect. On the other hand, the rejection of membrane separation to the organic macromolecule with smaller pore size can ensure that the filtered effluent is stable in bacteria removal, removal of suspended solids and stable in reduction of BOD.

•   Small footprint, membrane bioreactor can maintain a high concentration of sludge, usually MLSS 8~20g/l, it is 2.5 ~ 5 times of traditional biological treatment, while the system eliminates two sinks and sludge reflux equipment, thus covering the area of the province.

•   The cost of sludge water is low, the system sludge concentration is high, the mud age is long, which is not conducive to the propagation of filamentous bacteria, and there is no sludge bulking problem. The sludge is in the state of endogenous respiration, less sludge discharge and only 50% of the sludge production, which is very beneficial to the subsequent sludge treatment.
