Nanjing Weihua Membrane Technology Co., Ltd., established in 2022, is a national high-tech enterprise specializing in the R&D, production, and sales of polymer nanofiltration membranes and related module products.

Leveraging the National Engineering Research Center for Special Separation Membrane Technology of Nanjing Tech University, the State Key Laboratory of Materials-Oriented Chemical Engineering, and the Membrane Science and Technology Research Institute of Jiangsu Industrial Technology Research Institute, the company has built 6,000 square meters of R&D and production facilities in Nanjing and Kunshan. It has established a full-process industrialization platform encompassing R&D, pilot-scale production, manufacturing, and testing of core products such as spiral-wound flat-sheet nanofiltration membranes and hollow fiber nanofiltration membranes.

With its R&D team dedicated to nanofiltration membrane research for over adecade, the company has developed high-precision nanofiltration membranes featuring controllable pore size and surface charge using its proprietary"Molecular Encapsulation" patent technology. For diverse application scenarios, it has continuously launched specialty nanofiltration membranes including acid-resistant, alkali-resistant, solvent-resistant, and high-temperature-resistant grades. These products have been successfully applied in drinking water purification, biopharmaceutical purification, industrial wastewater treatment,and lithium extraction from salt lakes.

Guided by its mission to "develop the best nanofiltration membranes, support industrial decarbonization, and enhance health through clean water," the company is committed to serving industrial environmental protection and human health with high-quality products, working alongside partners to realize avision of "green mountains and clear waters, a thriving and beautiful China."
