    Product Description

    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.

    Technical Flowchart

    l Technological Process:
    Sewage Grille Regulating pond MBR Bioreactor Discharge(reuse)
    1. Temperature: 5℃~45℃, average membrane aperture 0.10 m.
    2. PH: 2~12, membrane thickness: 40m.
    3. Outlet water turbidity1 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.


    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, greatly improve the
    quality of the output water and reduce the operating cost and widen the scope of application of water.
    4. Due to the strong interception function of MBR, it can keep the microbe in the reactor to avoid the loss of all kinds of microbe groups, which
    is good for the growth of the bacteria (such as the nitrifying bacteria), at the same time, it can lengthen the residence time of difficult degradable
    macromolecule organics to improve the decomposition so as to make the metabolic system process smoothly. The system has a strong impact
    resistance and wide suitability.
    5. It can realize the completely separation of HRT and SRT. By the extended aeration, it can consume the organics, it can theoretically achieve
    the effect of no excess sludge emissions, thus reduce the surplus sludge treatment costs significantly.
    6. The unique mode of operation makes
