Some Misunderstandings about the MBR Process ③

Time: 2020-07-19 Hits: 159

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 3: MBR process does not require sludge discharge


Correct interpretation: Due to the excellent retention effect of membrane filtration, the activated sludge in the MBR process can reach a higher concentration, and the separation of hydraulic retention time and sludge age can be achieved without considering the effect of sludge concentration on the effluent.


However, this advantage only enhances the biochemical play space, does not affect the effluent and cannot be used as a reason to support sludge discharge. The problem of sludge discharge still needs to be returned to activated sludge.


If the sludge is not discharged, the activated sludge will have aging problems, which will affect the biochemical performance and affect the aeration.


Therefore, the MBR process in the project can indeed reduce sludge, but sludge is also required.

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