Against the backdrop of increasingly severe global water scarcity and environmental pollution, the water treatment industry is facing unprecedented challenges. As an important additive in water treatment processes, defoamers play a crucial role in improving water treatment efficiency and ensuring water quality safety. However, traditional defoamers often contain harmful chemical components to the environment, posing potential threats to water bodies and ecosystems. Therefore, the research and application of green water treatment defoamers have become a new driving force for promoting the sustainable development of the water treatment industry.

Green water treatment defoamers use renewable resources as raw materials and are prepared through green chemistry and biotechnology, with many advantages. First, green defoamer has excellent defoaming performance, which can rapidly reduce the thickness of foam layer in a short time and improve water treatment efficiency. Secondly, green defoamers have low toxicity and biodegradability, are harmless to water bodies and ecosystems, and meet environmental protection requirements. Finally, green defoamers have a wide range of applications and can be used in wastewater treatment processes in industries such as textiles, printing and dyeing, papermaking, and chemical engineering. They can also be applied in the purification of urban sewage treatment and agricultural irrigation water bodies.

The research and application of green water treatment defoamers play an important role in promoting the sustainable development of the water treatment industry. Firstly, the promotion and use of green defoamers will reduce chemical pollution in the water treatment process, improve water quality safety, and safeguard the lives and health of the people. Secondly, the application of green defoamers will promote innovation and development in water treatment technology, improve water treatment efficiency, reduce water treatment costs, and provide strong support for the sustainable development of the water treatment industry. Finally, the research and application of green defoamers will promote the green transformation of the water treatment industry and drive it towards green, environmentally friendly, and sustainable development.

Although green water treatment defoamers have many advantages, they still face some challenges in practical applications, such as cost issues, performance stability, and compatibility with other water treatment agents. To address these challenges, the government and enterprises should adopt the following strategies: firstly, strengthen technology research and development, improve the performance and stability of green defoamers, while reducing production costs; Secondly, strengthen policy guidance and support to promote the research and application of green defoamers; The third is to strengthen industry exchanges and cooperation, and jointly promote the green development of the water treatment industry.

Green water treatment defoamers are a new driving force for promoting sustainable development in the water treatment industry. In the future, with the continuous progress of green chemistry and biotechnology, as well as the increasing support from governments and enterprises for the research and application of green defoamers, the performance of green defoamers will be further improved, and their application fields will be more extensive. Meanwhile, the promotion and use of green defoamers will drive the green transformation and sustainable development of the water treatment industry.
