In the complex process of water treatment, the generation of foam is a prevalent yet often underestimated issue. These seemingly harmless foams actually pose various threats to the water treatment system, directly affecting the efficiency of water treatment and the quality of effluent water. With increasingly stringent environmental regulations, increasing pressure from water scarcity, and continuous advancements in water treatment technology itself, water treatment defoamer technology now stands at a crossroads full of opportunities and challenges. The future direction of development for water treatment defoamers is a question worthy of our consideration.

The research and development of green and environmentally friendly defoamers has become the most prominent development direction in the industry. Today, with the concept of sustainable development deeply rooted in people's minds, substances that may pollute the environment in traditional defoamers are gradually being phased out, and replaced by new environmentally friendly formulations that are biodegradable, low-toxic, or even non-toxic.

With the development of science and technology, the deep integration of intelligent control technology and defoaming agents represents another important development direction. Traditional methods of adding defoaming agents often involve fixed dosages or empirical adjustments, which can easily lead to insufficient addition or excessive waste. With the development of sensor technology, automatic control technology, and artificial intelligence technology, intelligent defoaming systems are becoming increasingly popular among enterprises.

Multi-functional integration is another important direction for technological innovation in defoaming agents. Traditional defoaming agents have a single function, focusing solely on the core task of foam elimination. However, the complexity and integrity of modern water treatment systems require defoaming agents to fulfill their primary function while also taking into account other auxiliary functions, achieving the comprehensive goal of "one agent, multiple effects".

It can be foreseen that the functional boundaries of defoamers will continue to expand in the future, creating more added value for water treatment processes. The development direction of defoamers in the future will exhibit distinct characteristics such as greenification, intelligence, and diversification. Technological innovation and interdisciplinary integration will become the core driving force for the development of the water treatment industry.
