The green and sustainable development of water treatment defoamers faces both numerous challenges and enormous opportunities. In the future, we should face challenges, seize opportunities, and promote the green transformation and upgrading of the water treatment defoamer industry.

Currently, the performance and stability of biodegradable defoamers still need to be improved, making it difficult to meet the needs of all water treatment scenarios. The production cost of environmentally friendly defoamers is often higher than that of traditional defoamers, which to some extent limits their market promotion and application. Some countries and regions lack policy support for environmentally friendly defoamers, and there is a lack of clear regulations and standards to guide the green development of the industry.

With the increasing global awareness of water resource protection and environmental protection, the market demand for environmentally friendly defoamers will continue to grow. The continuous emergence of innovative technologies such as biodegradation technology and green chemistry principles provides strong support for the green and sustainable development of water treatment defoamers. The increasing global cooperation in environmental protection provides a broad stage for green technology innovation and industrial upgrading in the water treatment defoamer industry.

Faced with challenges and opportunities, the water treatment defoamer industry should actively respond to national environmental policies, increase research and development investment, promote technological innovation and industrial upgrading, strengthen international cooperation and exchanges, and jointly promote the green and sustainable development of water treatment defoamers. At the same time, the government and relevant industry organizations should strengthen policy guidance and supervision to provide strong guarantees for the green and sustainable development of the industry.
