In the field of water treatment, the problem of foam has always been a difficult problem for many factories and enterprises. These foam not only affect the treatment efficiency, but also may have a serious impact on the water quality, leading to serious consequences such as substandard water quality. In order to solve this problem, water treatment defoamer emerged as the times require and became the key tool to solve the foam problem.

The generation of foam in the process of water treatment often comes from a variety of factors, such as the decomposition of organic matter in sewage, the presence of surfactant, mixing and aeration and other operations. The accumulation of these foam on the water surface will not only affect the appearance of the treatment facilities, but also interfere with the treatment process and reduce the treatment efficiency. The existence of foam will hinder the transmission of oxygen, affect the growth and metabolism of microorganisms, and then affect the entire biological treatment process. In addition, foam may also block equipment such as pipes, pumps and filters, increasing maintenance and replacement costs.

Water treatment defoamer is a chemical additive specially used to eliminate foam generated in water treatment process. The basic principle is to reduce the surface tension of the liquid, destroy the stability of foam, and make the foam burst and disappear quickly. Different types of defoamers have different action mechanisms, for example, surfactant defoamers destroy the stability of foam film by reducing the surface tension of the liquid; Organosilicon defoamers are known for their excellent defoaming performance and high temperature resistance; Polymer defoamers achieve defoaming effect by adsorption and destruction of foam film.

Take the sewage treatment plant as an example, because the sewage contains a lot of organic matter and surfactant, it is easy to produce a lot of foam in the process of aeration and mixing. After the use of water treatment defoamer, these foam are eliminated rapidly, which not only improves the efficiency of sewage treatment, but also ensures the normal operation of the equipment. In addition, foam problem is also common in industrial circulating cooling water system. By adding an appropriate amount of water treatment defoamer, foam can be effectively eliminated, cooling effect can be improved, energy consumption can be reduced, and equipment corrosion and damage can be prevented.

Water treatment defoamers play an indispensable role in the field of water treatment. Through reasonable selection and use of defoamers, the foam problem can be effectively solved, and water treatment efficiency and water quality safety can be improved. In the future, with the continuous advancement of technology and the increasing demand for environmental protection, the performance and application scope of water treatment defoamers will continue to expand and improve.
