China's reverse osmosis membrane industry continues to develop but there is still a gap with leading foreign companies

The reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membranes. It is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate other substances from water based on the inability of other substances to pass through the semi-permeable membrane under the action of a higher osmotic pressure than the solution. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.
The research and development of reverse osmosis membranes in China began in the 1970s, and achieved certain achievements in the 1990s through technology introduction and independent research and development. Since entering the 21st century, my country’s reverse osmosis membrane production technology has continued to improve. The performance and application technology of the reverse osmosis membranes produced are close to the international advanced level. The production scale of domestic reverse osmosis membranes has also continued to expand. According to the released “Research Report on Investment Prospects and Investment Strategies of the Reverse Osmosis Membrane Industry in 2022“, in 2021, China’s reverse osmosis membrane The output exceeds 20 million square meters.
In recent years, with the development of China’s environmental protection, chemical industry, food and other industries, China’s reverse osmosis membrane market demand has continued to grow, providing good market conditions for the technological advancement and scale expansion of China’s reverse osmosis membrane industry. Based on the good market environment, China’s reverse osmosis membrane industry has increased investment in technology research and development, actively introduced foreign advanced technology and high-quality materials, produced reverse osmosis membranes, and made many achievements in new product development. However, due to the late start of the domestic reverse osmosis membrane industry, relatively weak technology accumulation, and the quality of basic materials that need to be improved, the quality and performance of China’s domestic reverse osmosis membrane products are still relatively weak. This has led to Dow, Toray, and Nitto Denko International leading brands such as , LG and LG occupy a dominant position in China’s reverse osmosis membrane market. Among them, Dow and Nitto Denko occupy a large market share by virtue of their leading technology and brand effect. At present, the main local reverse osmosis membrane companies with certain technical strength and brand influence include Times Wharton, Blue Star Toray and Qinsen Hi-Tech.
Analysts believe that after long-term development, China’s reverse osmosis membrane industry has begun to take shape, with a large number of products in the field of mid-to-low-end products. Strong competitive advantages, and active market expansion with high cost performance and fast user response capabilities, promote the large-scale and industrial development of China’s reverse osmosis membrane industry. However, compared with leading foreign companies such as Dow and Toray, China’s reverse osmosis membrane industry is relatively small in scale and is limited by its technical level. Its high-end product development and industrialization capabilities are seriously insufficient. In the future, based on the good market prospects, China’s reverse osmosis membrane industry will accelerate the pace of development, increase investment in the transformation of research results, technology introduction, and the production and promotion of new products, expand product production scale, enhance the industry’s industrialization capabilities, and reduce The gap with leading foreign brands such as Dow and Toray.
