With the increasing scarcity of global water resources and worsening water pollution problems, the importance of water treatment technology has become increasingly prominent. In the process of water treatment, the production of foam often affects the treatment efficiency and water quality safety. Therefore, choosing the appropriate defoamer becomes the key to solving this problem. In today's deeply rooted environmental protection concept, it is particularly important to choose and apply water treatment defoamers from an environmental perspective.

In the process of water treatment, the production of foam mainly comes from surfactants, organics, microbial metabolites, etc. in the water. These substances form stable bubbles under physical actions such as mechanical agitation and aeration, and then aggregate into foam. The existence of foam will not only reduce the operation efficiency of water treatment equipment, increase energy consumption, but also may carry pollutants, affect the effluent quality, and even pose a potential threat to the ecological environment.

Excellent environmentally friendly defoamers should have good biodegradability, be able to quickly decompose in natural environments, and reduce long-term impact on the environment. Defoamers should be non-toxic or low toxic, and harmless to human health and the environment. When choosing, priority should be given to non-toxic or low toxicity ingredients, and the use of toxic and harmful substances should be avoided. During use, no new pollutants should be generated to avoid secondary pollution of water quality. This requires the defoamer ingredients to be pure and free of harmful elements such as heavy metals and halogens. The environment-friendly defoamer should have efficient defoaming and foam suppression capabilities, which can quickly destroy the foam structure in a short time, inhibit the regeneration of foam, and improve the water treatment efficiency. Defoamers should remain stable under different water quality, temperature, pH values, and other conditions to ensure long-term effective defoaming effects.

In the process of urban sewage treatment, the environment-friendly defoamer can effectively remove foam in aeration tank, sedimentation tank and other links, improve the efficiency of sewage treatment, reduce the content of suspended solids and organic matter in the effluent, and improve the water quality. In view of the foam problem in the treatment of industrial wastewater such as papermaking, printing and dyeing, and pharmaceuticals, the environment-friendly defoamer can quickly destroy the foam, reduce the chemical oxygen demand and biological oxygen demand in the wastewater, and reduce the burden of subsequent treatment. In the process of seawater desalination, the environment-friendly defoamer can effectively remove the foam generated by organic matter and microbial metabolism, ensure the stable operation of the desalination system, and improve the desalination water quality.

With the increasingly strict environmental regulations and the improvement of public environmental awareness, environmentally friendly defoamers will become the mainstream of water treatment defoamers in the future. Developing more efficient and environmentally friendly defoamer components, improving the biodegradability and low toxicity of defoamers, will be an important direction for the future development of the defoamer industry. At the same time, the application of intelligent and automated technologies will also promote the innovation of the use of defoamers, achieving more precise and efficient defoaming effects.

From an environmental perspective, selecting and applying water treatment defoamers is an important measure to ensure water quality safety and promote the recycling of water resources. Environmentally friendly defoamers have shown broad application prospects in the field of water treatment due to their excellent biodegradability, low toxicity, and no secondary pollution. In the future, with the continuous advancement of technology and the improvement of environmental awareness, environmentally friendly defoamers will become the mainstream products in the water treatment defoamer industry, contributing to water resource protection and ecological environment improvement.
