Membrance bioreactor sewage water treatment system
What is the MBR?
Membrance Bioreactor(MBR) is a kind of advanced technology
developed since the end of 20th century which realized the
efficient combination of menbrance separation technology with
biological technology .The menbrance separation separation
technology replaces the traditional active sludge method and the
noraml filter unit ,its strong separation ability can make the SS
turbidity near to be zero Hydraulic retention time sludge age 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 .

Because of the high-efficiency solid liquid separation ,it can
efficiently remove the SS ,colloidal material and dead mircobe in
the sewage, no dead sedimentation tank ,or filter device ,nor other
solid-liquid separation device .
The MBR can make the biomass in biological treatment unit maintain
high concentration ,thus highly improve the volume loading
.meanwhile ,the high effcient membrance separation can shorten the
HRT .The device is with a compact structure and small space
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
Due to the strong interception function of MBR,it can keep the
mircobe in the reactor to avoid the loss of all kinds of mircobe
groups.which is good for the growth of the 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 s strong
impact resistance and wide suitability .
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 sigificantly .
The unique mode of operation makes the membrance surface no
blocking ,and the cleaning interval time is long .the way to clean
the menbrance is easy .since the menbrance module can be separately
cleaned ,thus the maintenance is convenience and simple .the module
design make the machine flexible ,it is easy to expand volume .
