In modern industrial production and environmental protection, water treatment is a crucial link. Whether it is drinking water purification, industrial wastewater treatment, or sewage recycling, it is necessary to ensure the safety and purity of water quality. However, in the process of water treatment, the generation of foam often becomes a thorny problem. Foam not only affects the treatment efficiency, but also may carry pollutants, causing secondary pollution to the water quality. Therefore, the selection and application of defoamers for water treatment are particularly important.

Defoamers for water treatment mainly achieve the purpose of defoaming by destroying the stability of foam. These defoamers usually contain special surfactants, which can rapidly penetrate into the liquid membrane of foam, reduce the surface tension of the liquid membrane, and thus cause the foam to burst. At the same time, some defoamers can also inhibit the formation of foam at the initial stage to prevent further formation of foam.

In the process of drinking water purification, defoamer can effectively remove the foam generated by coagulation, sedimentation and other links to ensure the water quality is clear and transparent. Defoamers can significantly improve treatment efficiency and reduce equipment blockages for wastewater containing a large amount of surfactants generated in industries such as chemical, textile, and papermaking. In the wastewater treatment and reuse system, the application of defoamer helps to reduce the interference of foam on membrane filtration, bioreactor and other equipment, and ensure the reuse water quality.

When choosing a suitable water treatment defoamer, factors such as chemical stability, biodegradability, impact on water quality, and cost-effectiveness should be considered. At the same time, customized selection is made based on specific treatment processes and water quality characteristics to achieve the best defoaming effect.
