The biochemical pool is a key link in the water treatment process, especially when treating sewage. It mainly relies on the metabolism of microorganisms to decompose organic pollutants in water. Microorganisms such as bacteria, fungi and protozoa convert organic matter in sewage into carbon dioxide, water and the biomass of the microorganisms themselves. Therefore, the emergence of defoamers for biochemical pool water treatment has become the key to eliminating foam.

Defoamers for biochemical pool water treatment can quickly reduce the stability of foam. When the defoamer is added to the biochemical pool, it spreads on the surface of the foam and destroys the elastic membrane structure of the foam. For example, some silicone oil defoamers, their low surface tension characteristics enable them to quickly penetrate into the foam film, thinning the foam film until it breaks.

Defoamers for biochemical pool water treatment have little effect on the activity of microorganisms. It will not control the normal metabolic process of microorganisms and will not cause large-scale death of microorganisms. This is because suitable defoamers will not interfere with the basic environment for the survival of microorganisms while playing the defoaming and anti-foaming functions, such as changing the pH value, temperature and availability of nutrients in the biochemical pool.

The defoamer should be selected according to the characteristics of the foam in the biochemical pool. If the foam is stubborn, you need to choose a defoamer with strong defoaming ability and fast speed. For example, for those thick foams caused by high concentrations of oil, a defoamer containing special active ingredients may be needed to effectively eliminate them.

The defoamer for biochemical pool water treatment plays an important role in ensuring the normal operation of the biochemical pool and improving the efficiency and quality of water treatment. When selecting and applying defoamers, it is necessary to comprehensively consider multiple factors such as defoaming performance, biocompatibility and environmental friendliness.
