Nanofiltration membranes have broad application prospects and domestic companies have large room for improvement

Nanofiltration membrane refers to a functional semipermeable membrane with a pore size between 1-2nm that allows solvent molecules or certain low molecular weight solutes or low-priced ions to pass through. As a new type of separation membrane, nanofiltration membrane has the characteristics of high selectivity, low energy consumption, and simple operation. It is generally used to remove organic matter, pigments and partially dissolved salts, and is widely used in sewage treatment, food, biomedicine, dye purification, and pharmaceuticals. areas of separation. In recent years, with the development of my country’s membrane industry and increasingly strict environmental protection supervision, the market demand for nanofiltration membranes has continued to increase.

According to the “2022-2026 Nanofiltration Membrane Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, in In the global market, the nanofiltration membrane market is mainly distributed in North America, Europe and the Asia-Pacific region. In 2020, the growth rate of the global nanofiltration membrane market has slowed down compared with 2019, with market sales reaching about US$290 million. In recent years, my country’s economy has shown steady growth, and the growth rate of the nanofiltration membrane market is higher than the global average. In 2020, my country’s nanofiltration membrane market sales exceeded US$100 million.

my country’s nanofiltration technology research started early, but its development and application started late. At present, my country’s nanofiltration membrane market is still in a development period. Restricted by factors such as technology, experience, brand, and channels, the current global and Chinese nanofiltration membrane markets are still dominated by foreign companies. Among them, American Filmtec, Japan’s Nitto Denko, Toray, DuPont, Suez and other companies have relatively high levels of research and development and production of nanofiltration membranes and are in a leading position in the world. At this stage, the companies engaged in the research and production of nanofiltration membranes in my country mainly include Qinsen High-tech, Times Wharton, Shandong Jiuzhang, Bishuiyuan, etc.

Nanofiltration membranes have a wide range of downstream applications. Currently, the drinking water and sewage treatment industries are the main application areas of nanofiltration membranes, accounting for up to 70% of applications. In recent years, with the advancement of nanofiltration membrane technology and increasingly strict environmental protection supervision, the application scenarios of nanofiltration membranes in my country have gradually expanded, and emerging fields include new energy, artificial intelligence, 5G base station construction, rail transportation, etc. Benefiting from the gradual expansion of application fields, nanofiltration membranes have broad application prospects. In order to compete for more market shares, relevant companies should not only expand the production scale of nanofiltration membranes, but also improve the quality of nanofiltration membrane products and enrich the types of nanofiltration membrane products. As market demand escalates, companies with advantages in technology, scale, quality, etc. have more competitive advantages.

Industry analysts said that as an emerging membrane product, nanofiltration membranes have excellent comprehensive performance, a wide range of applications, and are in a continuous expansion trend. , nanofiltration membrane application prospects are good in the future. At present, my country’s nanofiltration membrane market is in development, and its growth rate is higher than the global average. However, in the international market competition, my country’s nanofiltration membrane companies still do not have advantages in terms of scale, quality, brand effect, etc., and domestic companies have large room for improvement. .
