The MBR membrane separation bioreactor developed by our company is to return solid organic matter to the reactor through the membrane module to discharge the treated organic water. The types of membrane separation bioreactor can be classified according to the location of membrane module and bioreactor, including membrane bio-integrated reactor, MBR membrane bio-separation reactor and membrane bio-composite reactor. MBR MBR membrane bio-separation reactor is filtered by pressurized mixture under pressure, so macromolecular organic matter will be filtered out by the membrane and degraded by the bio-reactor, so the organic matter in organic wastewater can be further decomposed by recycling operation. Separated membrane bioreactor (SMBR) is an effective way to treat organic wastewater because of its stability, easy operation and easy cleaning of membranes. However, in order to increase the pressure of circulating pump, high kinetic energy will be consumed. MBR membrane bio-integrated reactor
