What are the advantages and disadvantages of mbr method of domestic wastewater treatment

Advantages:?

1. Due to the high efficiency of the membrane separation, the separation effect is much better than the traditional sedimentation tank, the treated water is extremely clear, suspended solids and turbidity is close to zero, the effluent water quality is good and stable;?

2. High volumetric load, short residence time, small footprint;?

3. Low residual sludge production

4. Strong resistance to load impact, can remove ammonia nitrogen and difficult to degrade organic matter

5. Most of the disease-causing bacteria can be blocked, reducing the amount of disinfectant?

6. Simple operation and management, easy to realize automatic control;?

7. Can be used as a traditional sewage treatment process of the depth of the treatment unit, in the city of secondary sewage treatment plant effluent depth treatment (thus realizing a large number of urban wastewater reuse) and other areas have broad prospects for application.

Disadvantages:?

1 membrane cost is high, so that the membrane - bioreactor infrastructure investment is higher than the traditional sewage treatment process;?

2 Membrane contamination is easy to appear, bringing inconvenience to the operation and management;?

3 High energy consumption, energy consumption is the main reason for the high operating costs of MBR.
