Nowadays, in the process of water treatment, foam has always been an important factor affecting the treatment efficiency and operation stability. Whether it is industrial wastewater treatment, urban wastewater treatment or various circulating water systems, the generation of foam will bring many hazards, including reducing mass transfer efficiency, hindering microbial activity, causing equipment failure and affecting effluent quality.

As a functional chemical specially designed to eliminate and inhibit foam, defoamer for water treatment effectively solves this problem by destroying the stability of foam, reducing surface tension and other mechanisms. With the industrial production and urban development, the problem of foam in the water treatment process has become increasingly prominent. These foam are mainly composed of surfactants, impurities and other chemicals. They are formed due to various chemical reactions or physical operations in the water treatment process. If not controlled in time, these foam will seriously affect the efficiency and effect of water treatment, and even lead to substandard effluent quality.

With the improvement of environmental protection requirements and the advancement of sewage treatment technology, the research and development of defoamers are also constantly innovating. Nowadays, water treatment defoamers are usually made from environmentally friendly formulas, non-toxic and harmless, suitable for various foaming systems such as pharmaceuticals, papermaking, leather, printing and dyeing, urban sewage biological treatment processes, and chemical cleaning. These defoamers usually exist in the form of milky white or light yellow liquid, with good water solubility and dispersibility, and can quickly penetrate into foam to destroy its stability, so as to achieve the purpose of defoaming.

Water treatment defoamers have become an indispensable key component of modern water treatment technology systems due to their fast and efficient defoaming ability, excellent environmental performance, wide applicability, and significant economic benefits. With the continuous development of water treatment technology and the increasing demand for water quality, the advantages of defoamers will be further strengthened and expanded, providing stronger support for the sustainable development of the water treatment industry.
