During the water treatment process, the generation of foam will affect the treatment effect and equipment operation, so defoamers are needed to eliminate foam. Although traditional silicone defoamers have good defoaming effects, there are some environmental and process problems, such as not easy to degrade, high conductivity or vacuum abnormalities in some systems, etc. As a new type of defoamer, silicon-free water treatment defoamer has unique performance advantages and has gradually attracted widespread attention.

Silicon-free water treatment defoamers mainly achieve defoaming function by reducing the surface tension of the foam liquid film. When the defoamer is added to the system containing foam, it can quickly disperse on the foam surface, destroy the elastic film of the foam, and cause the foam to break and disappear.

During the wastewater treatment process of the printing and dyeing plant, the foam problem is serious due to the large amount of surfactants in the wastewater. After adding the silicon-free water treatment defoamer, the foam problem was effectively solved, the wastewater treatment effect was significantly improved, and the defoamer had no negative impact on the subsequent wastewater reuse and discharge treatment.

During the operation of the aeration tank of a domestic sewage treatment plant, a large amount of foam was generated due to excessive aeration volume and fluctuations in the concentration of organic matter in the influent, which affected the normal operation of sewage treatment. By using silicon-free water treatment defoamers, the generation of foam was successfully suppressed, ensuring the stable operation of the sewage treatment plant.

Silicon-free water treatment defoamers play an important role in water treatment. It can effectively eliminate foam, improve water treatment efficiency and quality, and meet environmental protection requirements. With the continuous advancement of science and technology and the increase in market demand, the performance of silicon-free water treatment defoamers will continue to improve, and the application field will continue to expand.
