The summary of MBR operation


1 Real-time monitoring the key parameters, such as TMP and turbidity, find problems and solve them in time to avoid the irreparable damage.


2 Strengthen the membrane system pre-treatment process, using a small aperture (≤ 1mm) grid as much as possible to prevent the fibrous objects, such as hair, entering system prevents the fiber be wounded, resulting in a reduction in membrane area.


3 The sludge concentration and SRT should be determined, according to the specific conditions, and the high sludge concentration and long SRT should not be pursued blindly.


4 A reasonable and applicable physical or chemical cleaning solution is required.


5 Properly reduce the membrane flux, increasing the membrane aeration, and coordinate the reasonable biochemical OD.
