Foam problem in sewage treatment and its comprehensive solution

2024-07-04

In the process of sewage treatment, there is often a large number of bubbles in the biochemical tank, which will not only overflow the outside of the tank when it is still, pollute the external equipment and the wall of the pool, but also deteriorate the operating environment and have a serious impact on the surrounding environment. In order to effectively deal with this problem, we need to have a deep understanding of the types of bubbles, causes, hazards and corresponding control methods.
