MBR craftsmanship municipal sewage treatment experimental device

The MBR process is a new sewage treatment technology combining membrane separation technology with biological treatment technology. It is m--nly composed of anaerobic and aerobic biological treatment devices, membrane separation components, sludge concentration and return system. Most organic objects in the sewage are decomposed by microorganisms. The membrane separation component cuts the particles and microorganisms in the mixed diameter than the diameter of the membrane pores, so as to get clear water.
