The ceramic ultrafiltration membrane industry is gradually developing towards standardization and high quality, with the seawater desalination field being its main demand end.

Ceramic ultrafiltration membrane refers to an inorganic separation membrane that can precisely filter and separate substances. Compared with other ultrafiltration membranes, ceramic ultrafiltration membranes have the advantages of small pore size, high filtration accuracy, large flux, can be used to process high-viscosity substances, high mechanical strength, acid and alkali resistance, long service life, and good temperature resistance. It is widely used in many fields such as food processing, seawater desalination, water treatment, construction engineering, medical care, metallurgy, electronic and electrical, agriculture, etc.

Ceramic ultrafiltration membrane preparation methods include chemical vapor deposition, sol-gel method, dip coating method, etc. The chemical vapor deposition method is an emerging preparation method for ceramic ultrafiltration membranes. This method has the advantages of good finished product quality, low equipment requirements, and fast deposition speed. It is expected to become the mainstream preparation method for ceramic ultrafiltration membranes in the future; the sol-gel method can be divided into The two process routes, polymer route and colloid route, can precisely control the membrane pore size and are the traditional preparation methods for ceramic ultrafiltration membranes.

According to the “2023-2028 China Ceramic Ultrafiltration Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , ceramic ultrafiltration membranes belong to a new generation of ultrafiltration membranes, which are in high demand in the fields of seawater desalination and water treatment. As a country with a large population, my country has a serious water shortage problem, which has driven the construction of seawater desalination projects to continue to accelerate. According to the “2021 National Seawater Utilization Report”, there are 144 seawater desalination projects in my country in 2021, with a project scale of 1,856,433 tons/day. Ceramic ultrafiltration membranes can increase the production capacity of seawater desalination projects. In the future, with the growth of downstream demand, its market space will be further expanded.

​​​​​​​​​​​​​​​With the continuous expansion of the application range of ceramic ultrafiltration membranes, its industry standards have also been further improved. In 2021, the group standard “Tubular Ceramic Ultrafiltration Membrane Modules for Water Treatment (T/CAMIE 11-2021)” jointly drafted by Tsinghua University, Tsinghua Suzhou Environmental Innovation Institute, Pall Group and other scientific research institutions and enterprises was officially released and implemented . Against this background, my country’s ceramic ultrafiltration membrane industry will gradually develop in a standardized and high-quality direction.

The main manufacturers of ceramic ultrafiltration membranes in my country include Safran Water, Sanda Membrane, Ultrafiltration Environmental Protection, Pall Group, Jiuwu High-tech, Beijite, Dazhi Technology, etc. Safran Water acquired the equity of German company ItN in 2016 and became my country’s leading ceramic ultrafiltration membrane enterprise. Nano-flat ceramic ultrafiltration membrane is the company’s main product, which has the advantages of strong oxidation resistance, good anti-fouling properties, and low production cost. It is widely used in the field of seawater desalination.

Industry analysts said that as a new generation of ultrafiltration membrane, ceramic ultrafiltration membrane has excellent comprehensive performance and has broad application prospects in many fields. . Benefiting from the accelerated construction of seawater desalination projects, the market demand for ceramic ultrafiltration membranes in my country is increasingly strong. In the future, as local companies continue to exert their efforts, my country’s ceramic ultrafiltration membrane market space will be further expanded.
