10 Leading nanofiltration membranes Manufacturers in China 2025

Introduction to Nanofiltration Membranes

Nanofiltration membranes are a type of semi - permeable membrane that have pores in the nanometer range, typically between 1 - 10 nanometers. These membranes are designed to separate different substances based on their molecular size, charge, and other physical and chemical properties. They are widely used in various industries such as water treatment, food and beverage processing, pharmaceutical manufacturing, and chemical separation.

In water treatment, nanofiltration membranes can effectively remove divalent ions, organic compounds, and some microorganisms, while allowing monovalent ions and small molecules to pass through. This makes them suitable for applications such as softening hard water, removing natural organic matter, and desalting brackish water. In the food and beverage industry, nanofiltration membranes are used for concentration, purification, and separation of various products, such as fruit juices, dairy products, and wine.
