In industrial wastewater treatment, circulating cooling water system and other fields, too much foam will lead to equipment efficiency decline, water quality deterioration and even environmental pollution. The defoamer for water treatment has become the key assistant to ensure the stable operation of water treatment process by rapidly eliminating foam. So how does the water treatment defoamer effectively break the foam problem?   

Defoamer molecules can rapidly spread on the surface of foam by reducing the surface tension of liquid film, causing the foam wall to burst. Our common water treatment defoamers can be divided into three categories. Firstly, there are organosilicon defoamers, which are characterized by high temperature resistance and strong chemical inertness, and are suitable for the treatment of high pH wastewater. Next is polyether based defoamers, which have the advantage of being easily dispersed in water and suitable for circulating cooling water systems. In addition, there are mineral oils, which have the advantage of low cost and are mostly used for papermaking and textile wastewater.   

When selecting defoamer, we also need to consider the pH of water quality, temperature and the type of foam. With the increasing improvement of green environmental protection laws and regulations, the degradability of defoamers should also be considered. Therefore, selecting appropriate defoamer is also one of the methods to effectively solve the foam problem.  

The water treatment defoamer seems insignificant, but it plays a key role in industrial water treatment. With the development of science and technology, the more efficient, green and intelligent defoamer will become the mainstream of the market in the future, which also lays the foundation for enterprises to break foam more efficiently.
