Membrane Bioreactor (MBR) is a kind of advanced technology developed since the end of 20th century which realized the efficient combination of membrane separation technology with biological technology. The membrane separation technology replaces the traditional active sludge method and the normal filter unit, its strong separation ability can make the SS turbidity near to be zero. Hydraulic retention time (HRT) sludge age (SRT) is completely separated, the outlet water is good and stable in quality, it can be reused without the third level treatment. Due to the high security and economic and effective water, it greatly expands the scope of application of waste water recycling. Technological Process: Sewage → Grille → Regulating pond → MBR Bioreactor → Discharge(reuse) 1. Temperature: 5℃~45℃, average membrane aperture 0.10 μm. 2. PH: 2~12, membrane thickness: 40μm. 3. Outlet water turbidity: ＜1 NTU , outlet water SS ＜1mg/L. 4. Membrane area: 8m2, advised gas-water ratio: 25:1~30:1. 5. Operating pressure: -0.01 ～ -0.03MPa. Features 1. Because of the high-efficiency solid-liquid separation, 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. Meanwhile, 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
