With the increasing awareness of global water resource protection and the continuous strictness of environmental policies, the water treatment industry is facing unprecedented transformation pressure. In this context, the green development of defoamers for water treatment has become a focus of industry attention.

In the future, defoamers for water treatment will pay more attention to the selection and application of environmentally friendly materials. Developing non-toxic, harmless, and biodegradable new defoamers based on natural polymers, biobased materials, and biodegradable materials will become the mainstream direction of industry development.

In addition to the basic defoaming function, future defoamers will also have more additional functions, such as antibacterial, anti-corrosion, self-cleaning, etc. These multifunctional designs not only improve the comprehensive performance of defoamers, but also provide more possibilities for their widespread application in the field of water treatment.

With the continuous development of intelligent technology, future water treatment systems are expected to achieve more precise control of defoamer dosage. Through intelligent sensors and control systems, the water quality and foam situation are monitored in real time, and the dosage and dosing time of defoamer are automatically adjusted, thus improving the treatment efficiency and resource utilization.

Although significant progress has been made in the research and development of green defoamers, there are still some technical bottlenecks that need to be overcome. For example, how to further improve the biodegradability and environmental friendliness of materials while ensuring the defoaming effect; How to reduce production costs and improve the market competitiveness of products, etc. Due to the fact that traditional defoamers have already occupied a certain market share, the promotion of new green defoamers may face market acceptance issues. Therefore, it is necessary to increase publicity efforts and enhance consumers' awareness and trust in green defoamers. Meanwhile, the government plays an important role in the formulation and implementation of environmental policies in the water treatment industry. In the future, it is necessary to further improve the relevant policy system, increase support for the research and promotion of green defoamers, and provide strong guarantees for the development of the industry.
