Seawater desalination membrane is a kind of reverse osmosis membrane. Compared with traditional reverse osmosis membrane, it has the advantages of strong pollution resistance, high salt rejection rate, various sizes and types, and low energy consumption. It is widely used in seawater cooling, seawater aquaculture, drinking water purification, etc. There is strong demand in desalination technology application scenarios such as industrial water purification. According to different base materials, seawater desalination membranes can be divided into two types: polyamide composite reverse osmosis membranes and cellulose acetate membranes.

Desalination technology refers to the technology that removes salt from seawater to produce fresh water, including membrane desalination technology and thermal desalination technology. Membrane seawater desalination technology usually uses reverse osmosis (RO) to achieve seawater desalination. It has the advantages of high technological maturity and little impact on seawater quality. Seawater desalination membranes are widely used in this technology. In recent years, driven by market demand, my country’s membrane desalination technology has continued to advance, which has accelerated the development of the desalination membrane industry.

According to the “2023-2028 China Seawater Desalination Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In terms of product segmentation, cellulose acetate membrane is the earliest seawater desalination membrane successfully developed. It has the advantages of oxidation resistance, not easy to scale, easy preparation, and high surface finish. However, it is susceptible to microbial erosion and has poor high temperature resistance. The polyamide composite reverse osmosis membrane is composed of a polysulfone ultrafiltration membrane, a non-woven physical support layer and a polyamide separation membrane. It has the advantages of long service life, good stability, corrosion resistance, high temperature resistance, etc., and has gradually become a popular choice for seawater desalination. Mainstream products in the membrane market.

In recent years, the country has attached great importance to the development of the seawater desalination membrane industry and introduced many relevant policies. The “Seawater Desalination Utilization Development Action Plan (2021-2025)” jointly issued by the National Development and Reform Commission and the Ministry of Natural Resources clearly states that it is necessary to accelerate the layout of the seawater desalination membrane manufacturing industry cluster and strengthen the development and application of membrane elements. In the future, with the support of national policies, my country’s seawater desalination membranes will gain broad market prospects.

In terms of market competition, many companies in my country have laid out seawater desalination membrane research and development and production tracks, mainly including Bishuiyuan, Wharton Technology, Huazi Technology, Jinmu Technology, Weisebo, etc. Bishuiyuan is a representative seawater desalination membrane enterprise in my country. Its independently developed high-performance seawater desalination reverse osmosis membrane has been applied in multiple seawater desalination projects.

Industry analysts said that in recent years, as the shortage of fresh water resources has become increasingly severe, the development speed of my country’s seawater desalination industry has continued to accelerate, driving the seawater The demand for desalination membrane applications has increased. Benefiting from national policy support and the improvement of the technical level of local enterprises, the quality of my country’s seawater desalination membranes has continued to improve. The polyamide composite reverse osmosis membrane has excellent comprehensive performance and has become a mainstream product in the seawater desalination membrane market. It is expected that in the future, companies with high-performance seawater desalination membrane mass production capabilities will occupy a larger space in my country’s market.
