my country’s nanofiltration membrane industry has broad development prospects and local companies have large room for improvement

Nanofiltration is an emerging green water treatment technology separated from reverse osmosis technology. It can pass 90% of sodium chloride and intercept 99% of sucrose. Nanofiltration membrane is a functional semipermeable membrane that allows solvent molecules, low-valent ions, and certain low-molecular-weight solutes to pass through. The minimum pore size range can reach about one nanometer. It has high selectivity, low energy consumption, and the ability to intercept low molecules. It has the advantages of strong strength, large water flux, and simple operation. It is an effective way to remove organic matter and color, remove some soluble salts, remove groundwater hardness, and separate pharmaceutical and useful substances. It is widely used in sewage and drinking water treatment, biomedicine , food, chemical industry, dye purification and other fields.

According to the“China Nanofiltration Membrane Market Feasibility Research Report 2023-2027” released by the Industrial Research Center, in recent years, my country has Residents’ living standards continue to improve, and their awareness of self-health and environmental protection continues to increase. The public has gradually stricter requirements for drinking water treatment, domestic wastewater purification, and industrial wastewater discharge, and has gradually paid more and more attention to the residual problems of pesticides and antibiotics in surface water. Against this background, emerging technologies are gradually being applied to the water treatment industry. Nanofiltration membranes have gradually become one of the mainstream technologies in the water treatment field due to their high selectivity, large water flux, simple operation, and good stability. Industry development Broad prospects.

In addition, with the rapid economic growth and the continuous advancement of industrialization, the environmental problems faced by our country have become increasingly prominent. In order to balance the contradiction between environmental governance and economic growth, green development has become an important development concept in our country. The government has successively promulgated the “Urban Wastewater Discharge into Policies such as “Measures for the Management of Drainage Pipe Network Licensing”, “Measures for the Management of the Directory of Key Environmental Supervision Units”, “Technical Specifications for Ecological Environment Statistics and Emission Source Statistics”. Under favorable policies, the sewage treatment industry has developed rapidly, driving the market demand for nanofiltration membranes to rise.

At this stage, the application of nanofiltration membranes in my country is mainly concentrated in the fields of industrial separation, recycled water treatment, seawater desalination, sewage/wastewater treatment and other fields. The industry is developing rapidly and the market size is continuously expanding. my country’s nanofiltration membrane market size was approximately 4.15 billion yuan in 2018 and approximately 9.48 billion yuan in 2022, an expansion of 5.33 billion yuan, with a compound annual growth rate of 23.0%. Among them, my country’s nanofiltration membrane market size will increase by 20.8% year-on-year in 2022. In addition, with the continuous breakthroughs in scientific research and technology of nanofiltration membranes in my country, the downstream application scenarios of nanofiltration membranes have gradually expanded. They have been put into use in emerging fields such as new energy, 5G base station construction, and artificial intelligence, and the industry is booming.

Industrial analysts said that my country’s theoretical research on nanofiltration technology began earlier, but the development and application of nanofiltration membranes have not yet been completed. It is in the preliminary stage and lags far behind developed countries such as the United States and Japan. At present, my country’s nanofiltration membrane market is mainly occupied by foreign companies such as American Filmtec and Japan’s Nitto Denko, leaving local companies with greater room for improvement. As my country’s nanofiltration membrane companies continue to improve their research and development technology and product quality gradually improves, the localization rate of nanofiltration membranes is expected to increase.
