Water treatment defoamers can be classified into various types based on their composition and mechanism of action, each with its unique characteristics and scope of application.

1、 Organosilicon defoamers are a common and efficient type of water treatment defoamer. It is mainly made of organosilicon compound, which can quickly destroy the surface tension in water, make bubbles burst quickly and eliminate foam. This defoamer has little impact on water quality and does not cause secondary pollution. It is widely used in industrial wastewater treatment, sewage treatment and other fields.

2、 Surfactant defoamer, surfactant defoamer eliminates foam by changing the surface tension of bubbles in water. This type of defoamer has good defoaming effect and stability, and is suitable for various water treatment systems. Its main components include non-ionic, anionic, cationic, and amphoteric surfactants, which can be flexibly selected according to specific working conditions.

3、 Mineral oil defoamer, composed of mineral oil and its derivatives, has good defoaming effect and stability. It can effectively reduce the surface tension in water, quickly eliminate foam, and has certain durability. This type of defoamer is suitable for various water treatment systems, such as industrial wastewater treatment, paper industry, etc.

4、 Organic solvent defoamer, organic solvent defoamer has the characteristics of quickly eliminating foam, has little impact on water body, and will not change the nature of water. Therefore, it is suitable for applications that require high water quality, such as drinking water treatment, pharmaceutical industry, and other fields.
