With the increasing severity of global water scarcity and environmental pollution, the water treatment industry is undergoing a transformation from high energy consumption and high pollution to green, environmentally friendly, and sustainable development. In this transformation process, the research and application of green water treatment defoamers are particularly important.

In recent years, with the rapid development of green chemistry and biotechnology, significant progress has been made in the research and development of green water treatment defoamers. Researchers have successfully prepared a series of green defoamers with excellent defoaming and environmental performance by screening renewable resources such as natural plant extracts and biobased materials. These green defoamers can not only rapidly reduce the thickness of foam layer in a short time, improve water treatment efficiency, but also rapidly degrade in the natural environment, reducing environmental pollution.

The application prospects of green water treatment defoamers are broad. In industrial production, green defoamers can be widely used in wastewater treatment processes in industries such as textiles, printing and dyeing, papermaking, and chemical engineering to improve wastewater treatment efficiency and reduce wastewater discharge. In urban sewage treatment, green defoamer can effectively remove foam in sewage, improve sewage treatment effect and ensure water quality safety. In addition, green defoamers can also be applied to the purification treatment of water bodies such as agricultural irrigation water and groundwater, providing strong guarantees for the sustainable utilization of water resources.

The research and application of green water treatment defoamers will have a profound impact on the water treatment industry. Firstly, the promotion and use of green defoamers will drive the transformation of the water treatment industry towards green, environmentally friendly, and sustainable development, and improve the environmental protection level of the water treatment industry. Secondly, the application of green defoamers will reduce water treatment costs, improve water treatment efficiency, and provide strong support for the sustainable development of the water treatment industry. Finally, the research and application of green defoamers will promote innovation and development in water treatment technology, and drive technological progress in the water treatment industry.

The research and application prospects of green water treatment defoamers are broad and will have a profound impact on the water treatment industry. In the future, with the continuous advancement of green chemistry and biotechnology, the performance of green defoamers will be further improved, and their application fields will be more extensive. At the same time, the government and enterprises should strengthen their support for the research and application of green defoamers, and promote the green development of the water treatment industry.
