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.
