NF Membrane

NF membranes are advanced filters that selectively remove divalent and larger monovalent ions, organic molecules, and contaminants from water. Positioned between ultrafiltration and reverse osmosis in filtration performance, they offer an efficient solution for applications needing partial salt rejection and high flow.

NF membranes (Nanofiltration membranes) are advanced filtration elements designed to selectively remove divalent and larger monovalent ions, organic molecules, and contaminants from water. Positioned between ultrafiltration and reverse osmosis in terms of filtration performance, NF membranes offer a highly efficient solution for applications where partial salt rejection and high flow are required.

At KaT Solution, we supply high-quality NF membranes from both Veolia and DuPont, two leading global manufacturers in membrane technology.

Key Benefits of NF Membranes

  • High rejection of divalent salts, hardness, color, and organic substances

  • Partial passage of monovalent salts like sodium and chloride

  • Low energy consumption due to lower operating pressure compared to RO membranes

  • High permeate flow and stable long-term operation

  • Ideal for process water, food & beverage, and wastewater recovery
