Membrane separation technology develops rapidly and ceramic nanofiltration membranes have broad application prospects

Nanofiltration membrane refers to a functional semipermeable membrane with a pore size above 1 nm that allows solvent molecules or certain low molecular weight solutes or low-priced ions to pass through. Nanofiltration membranes are usually divided into two categories: inorganic ceramic nanofiltration membranes and organic rolled nanofiltration membranes. Inorganic ceramic nanofiltration membrane, also known as ceramic nanofiltration membrane, has the advantages of good chemical stability, good thermal stability, acid and alkali resistance, and high mechanical strength. It is widely used in food processing, chlor-alkali chemical industry, water treatment, industrial flue gas desulfurization, and automobile exhaust. It is widely used in processing and other fields.

Membrane separation technology is the core technology of ceramic nanofiltration membrane. It refers to the technology that achieves selective separation when a mixture of molecules of different particle sizes passes through a semipermeable membrane. my country’s membrane separation technology research started relatively late, but with the support of national policies, local enterprises and scientific research institutions continue to be enthusiastic about research and development, which has led to the continuous expansion of the application range of membrane separation technology. At present, my country’s membrane separation technology has been widely used in many fields such as medicine, water treatment, and seawater desalination. Membrane separation technology continues to innovate and make breakthroughs, providing favorable conditions for the development of my country’s ceramic nanofiltration membrane industry.

The main raw materials of ceramic nanofiltration membrane include zirconia, alumina, titanium dioxide, silica, etc. Zirconia, also known as zirconium dioxide, is an inorganic non-metallic material with high refractive index, high melting point, low thermal expansion coefficient, and lightweight. In recent years, driven by technological innovation, my country’s zirconia production has continued to increase. Oriental Zirconium Industry is my country’s leading zirconia enterprise, with an annual production capacity of zirconia powder reaching nearly 5,000 tons. The wide sources and sufficient supply of raw materials provide favorable conditions for the development of my country’s ceramic nanofiltration membrane industry.

According to the “2023-2028 China Ceramic Nanofiltration Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Ceramic nanofiltration membranes have broad application prospects in food processing, chlor-alkali chemical industry, water treatment, industrial flue gas desulfurization, automobile exhaust treatment and other fields. In the field of food processing, ceramic nanofiltration membranes can be used for bovine colostrum sterilization, whey protein concentration, juice clarification, soybean deep processing, beer yeast removal, etc.; in the field of water treatment, ceramic nanofiltration membranes have good safety and long service life. and other advantages, it can be used for high-temperature condensate water treatment.

The main manufacturers of ceramic nanofiltration membranes in my country include Hefei Xinda Membrane Technology Co., Ltd., Nanjing Xuanke Environmental Protection Technology Co., Ltd., Nanjing Hongyi Ceramic Nanofiltration Membrane Co., Ltd., etc. At present, my country’s ceramic nanofiltration membrane market is dominated by small and medium-sized enterprises, and the industry concentration is low.

Industry analysts said that ceramic nanofiltration membranes, as a subdivided product of nanofiltration membranes, have a wide range of applications in many fields such as food processing and water treatment. Broad application prospects. In the future, with the continuous improvement of the technological innovation level of local enterprises and the increasingly strong market demand, the development speed of my country’s ceramic nanofiltration membrane industry will further accelerate. Overall, there is huge room for development in my country’s ceramic nanofiltration membrane industry.
