What are the industrial sewage technologies? Is defoamer useful?

Industrial sewage treatment technology includes a variety of methods and equipment, the following are some common methods and equipment:

1. Biological treatment technology: activated sludge method, biofilm method, constructed wetland, etc. Heterotrophic or autotrophic microorganisms degrade and remove organic matter through aerobic or anaerobic processes.

2. Physical and chemical treatment technology: adopt oxidation, reduction, precipitation, adsorption and other methods to achieve the purpose of removing pollutants from industrial sewage by chemical or physical means.

3. Membrane technology: Through microfiltration, ultrafiltration, nanofiltration and other methods, the pollutants are selectively intercepted and separated by using the pore size and characteristics of the membrane.

4. Other physical and chemical treatment technologies: electrochemical technology, ozone oxidation and advanced oxidation technology.

Defoamer mainly solves the problems that a large amount of foam produced in wastewater is difficult to remove and hygienic and safe. The main function of defoamer is to destroy the stability of foam and make it separate or dissolve in water for subsequent treatment. Therefore, defoamer can be used to eliminate foam when dealing with the foam problem in industrial sewage. But defoamer can't remove pollutants from industrial sewage, so defoamer can't replace the application of technology.

In a word, there are many kinds of industrial sewage treatment technologies, and different methods and equipment have their applicable scenarios. Defoamer can only solve the problem of foam in sewage, not all measures to treat industrial sewage. Choose and eat according to the actual situation when using.
