In the 21st century, with the increasingly severe problems of global water scarcity and environmental pollution, the efficiency and environmental protection of water treatment technology have become the focus of social attention. As a key additive for improving water treatment efficiency, water treatment defoamers are not only essential for industry transformation and upgrading, but also an important way to achieve water resource recycling and environmental protection goals through their green and sustainable development.

In the future, water treatment defoamers will increasingly use natural or renewable raw materials, such as plant extracts, biopolymers, etc., to reduce dependence on petroleum based chemicals and lower carbon emissions during production. Develop defoamers with high biodegradability to ensure that they can quickly and harmlessly decompose into the natural environment after completing the defoaming task, reducing potential impacts on the ecosystem. By optimizing the chemical structure, toxic and harmful substances in defoamers can be reduced or eliminated, ensuring safety and environmental friendliness during use. By utilizing the special properties of nanomaterials, we aim to develop nano scale defoamers with efficient defoaming performance and environmental friendliness, thereby improving treatment efficiency and reducing usage. By combining Internet of Things and big data technology, intelligent monitoring and regulation of defoamers can be achieved, and the addition amount can be automatically adjusted according to water quality changes and treatment needs, which is both energy-saving and efficient. Explore the recycling and reuse technology of defoamers after use, reduce resource waste, and promote circular economy.

In the future, the government should introduce more policies to encourage the research and application of green defoamers, such as tax incentives, R&D subsidies, etc., to stimulate the innovation vitality of enterprises. Establish and improve evaluation standards and certification systems for green defoamers, guiding the market towards a more environmentally friendly and efficient direction. Through education and publicity, enhance public awareness and demand for green defoamers, and form a market driven virtuous cycle.

The greening and sustainable development of water treatment defoamers is not only a challenge of technological innovation, but also a result of social consensus and policy guidance. Through the green transformation of raw materials, the application of technological innovation, and the dual drive of policies and markets, we are expected to build a more efficient and environmentally friendly water treatment defoamer ecosystem, contributing to water resource protection and global sustainable development.
