Seawater desalination is one of the important ways to solve the problem of global water shortage. The production of foam in the process of desalination will have adverse effects on the operation of equipment, water production efficiency and water quality. Environmentally friendly defoamers, as a key tool to solve this problem, are gradually being widely used in the field of seawater desalination, contributing to ensuring water resource security and sustainable development.

The environment-friendly defoamer can quickly destroy the foam structure, reduce the formation of foam, and thus improve the efficiency of seawater desalination. This helps to increase the production of effective water and meet the growing demand for water resources. The existence of foam will cause fluid flow instability in seawater desalination equipment, which will affect the operation of the whole system. The use of environment-friendly defoamer can effectively reduce the production of foam, maintain the stability of the fluid, and extend the service life of the equipment. Some pollutants may be enriched in foam, which will have a negative impact on water quality. The environment-friendly defoamer can reduce the formation of foam, thus reducing the impact of these pollutants on water quality and ensuring the quality of the final produced fresh water meets the standard requirements.

The continuous research and application of environmentally friendly defoamers for seawater desalination has promoted the innovation and development of seawater desalination technology. By adopting more environmentally friendly and efficient defoamer materials and processes, the efficiency and water quality safety of seawater desalination have been further improved. Faced with the challenge of global water scarcity, countries should strengthen international cooperation and exchanges in the field of seawater desalination technology. Jointly develop and promote the application of environmentally friendly defoamers and other green chemicals, contributing to the security and sustainable development of global water resources. By strengthening publicity and educational activities, we aim to enhance public awareness of water resource protection and sustainable utilization. Encourage people to actively participate in water-saving actions and water resource development activities such as seawater desalination, and jointly promote the realization of water resource security and sustainable development.
