The MBFB membrane biological fluidized bed process is used for advanced treatment of industrial wastewater. On the basis of the original wastewater discharge standards, it can further reduce COD, NH-N, turbidity and other indicators through the biological fluidized bed and ceramic membrane separation system. It can be reused directly. On the other hand, it can also be used as a pretreatment process for RO desalination, replacing the original sand filtration, security filtration, ultrafiltration and other lengthy filtration processes. At the same time, the reduction of organic content greatly increases the service life of the RO membrane and reduces the reused water. Treatment cost. The inorganic ceramic membrane separation system is the world's first inorganic membrane separation system dedicated to sewage treatment. Compared with other organic membranes and inorganic membranes, it has the advantages of large membrane flux, recoil, and fully automatic operation.
