Some Misunderstandings about the MBR Process ②

Time: 2020-07-10 Hits: 183

Do you really understand MBR technology? Are you familiar with how to use it?

In recent years, the MBR process has been widely used by people. The MBR process can be used in many applications such as reuse of reclaimed water, improvement of environmental standards, and dispersion treatment of wastewater. As we all know, the reason why the MBR process has so many widespread uses is mainly due to its outstanding advantages such as high load, long mud age, high efficiency of shutoff, and small footprint.

This article will continue to introduce you to misunderstandings about the application of the MBR process in wastewater treatment.


Misunderstanding 2: Once MBR is used, the effluent quality can be guaranteed.


Correct interpretation: The MBR process is essentially a combination of activated sludge method and membrane filtration. It is based on the traditional activated sludge method and replaces the secondary settling tank with membrane filtration.


Through this technology, it can bring the advantages of good interception effect and high sludge concentration. But this does not mean that once the MBR process is used, all sewage can be treated.


For the removal of pollutants, membrane filtration has a very obvious effect on SS, while the removal of organic matter still depends on the biodegradability of activated sludge and organic matter.


For sewage with poor biodegradability, MBR technology has limited effect. For wastewater that has been fully biochemically treated at the front end, the role of MBR technology is also limited.

In the next article, we will continue to introduce several other misunderstandings of the MBR process.
