What are the advantages and disadvantages of MBR and traditional technology? Mar 23, 2018


1. Convenient operation and management, easy to realize automatic control.

This technology has realized the hydraulic retention time (HRT) and sludge retention time (SRT) for complete separation, control is more flexible and stable operation, is easy to implement in sewage treatment equipment of new technology, which can realize the microcomputer automatic control, which makes operation more convenient management.

It is easy to transform from traditional technology.

The process can be used as a traditional wastewater treatment technology of deep processing units, depth of the secondary sewage treatment plant effluent treatment in the city (so as to realize of urban wastewater reuse), and other fields has a broad application prospect.

There are also some deficiencies in the membrane bioreactor.

It is mainly manifested in the following aspects:

O membrane cost is high, so the construction investment of membrane - bioreactor is higher than that of traditional sewage treatment.

O membrane pollution is easy to appear, which brings inconvenience to operation management;

O high energy consumption: first, the MBR membrane drive spate separation process must keep pressure, followed by the MLSS concentration in MBR pool is very high, to keep enough oxygen transfer rate, must increase the intensity of aeration, and in order to increase the membrane flux and reduce membrane pollution, must increase the flow velocity, scour the membrane surface, cause the energy consumption of the MBR is higher than the traditional biological treatment process.
