High-Performance Nanofiltration Membranes for Efficient Water Separation
The JNF nanofiltration series membrane elements adopt a brand-new coating technology. Their effective selective filtration characteristics are advantageous because there is no chemical reaction, no heating, no phase transformation, and no damage to biological activity during the separation process. The process requires lower pressure than reverse osmosis. They have been increasingly widely used in the preparation of healthy drinking water and in various separation, concentration and purification processes in the food, pharmaceutical, and biological industries.

How Nanofiltration Membranes Work
Nanofiltration (NF) is a pressure-driven membrane separation technology positioned between ultrafiltration (UF) and reverse osmosis (RO). It selectively removes multivalent ions, organic compounds, color, and larger dissolved molecules while allowing a portion of monovalent salts to pass through. This unique separation mechanism makes nanofiltration an ideal solution for water softening, resource recovery, and industrial process water treatment.
Feed Water Enters the Membrane
Feed water containing dissolved salts, hardness ions, organic matter, and suspended impurities is delivered to the nanofiltration membrane under moderate operating pressure.
Selective Molecular Separation
The membrane selectively retains multivalent ions, larger organic molecules, color compounds, and dissolved contaminants while allowing water molecules and part of the monovalent salts to pass through.
Permeate and Concentrate Formation
Purified water (permeate) is collected for reuse or further treatment, while concentrated contaminants are discharged through the concentrate stream.
Stable and Energy-Efficient Operation
Operating at lower pressure than reverse osmosis systems, nanofiltration provides excellent separation efficiency while reducing energy consumption and operating costs.
