In modern society, water treatment technology is of great significance in ensuring human domestic water, industrial water, and ecological environment health. However, in the process of water treatment, a large amount of foam is often produced due to factors such as added chemicals, organic substances in the water body and treatment technology. These foam not only affect the treatment efficiency, but also may cause secondary pollution to the environment. Therefore, the application of defoamers in water treatment is particularly important.

Defoamers used for water treatment mainly destroy the stable structure of foam to make it burst rapidly. Its mechanism includes reducing the surface tension of foam, accelerating the combination and collapse of bubbles, and interfering with the formation process of foam. Different types of defoamers, such as organosilicon defoamers, polyether defoamers, mineral oil defoamers, etc., have different defoaming effects due to their different chemical structures and physical properties.

In the process of domestic sewage treatment and drinking water purification, defoamer can effectively remove foam generated by biological treatment process to ensure water quality safety. In the process of wastewater treatment in the chemical, paper making, pharmaceutical and other industries, foam is particularly serious. The application of defoamer helps to control foam, improve treatment efficiency and reduce operating costs. In the cooling tower, circulating water pool and other water circulation systems, defoamers can prevent foam accumulation, ensure the normal operation of the system, and avoid equipment damage or operational efficiency decline caused by foam. For lakes and rivers with serious eutrophication and algae growth, defoamers can not only eliminate surface foam, but also create favorable conditions for other control measures.

When selecting defoamers for water treatment, the compatibility between the defoamer and the system should be considered to ensure that the defoamer can be evenly dispersed in the water and does not have adverse reactions with other substances in the water. Choose defoamers that can quickly defoam in a short period of time and maintain their anti foaming effect for a long time. On the premise of ensuring effectiveness, choose non-toxic, harmless, environmentally friendly, and use the safest and most cost-effective defoamer. During use, attention should also be paid to controlling the amount of defoamer added to avoid the negative effects of excessive use. At the same time, it is necessary to regularly test the water quality, evaluate the effectiveness of defoamers, and adjust the usage strategy according to the actual situation.

The application of defoamers in water treatment is of great significance for improving water treatment efficiency and ensuring water quality safety. The rational selection and use of defoamers can effectively solve the foam problem in the water treatment process and contribute to building a more healthy and green water environment.
