- Nanofiltration membrane elements of the NF90 series deliver high water production while providing excellent monovalent salt selectivity and effective divalent and multivalent salt rejection. They achieve a high removal rate of organic compounds, including pesticides, herbicides, TOC (total organic carbon), and THM (trihalomethane) precursors, demonstrating strong rejection of natural organic matter.
During water treatment, NF90 nanofiltration membrane materials not only reduce water hardness but also effectively remove toxic and harmful substances, turbidity, color, and organic contaminants. Additionally, they can separate, concentrate, and recover economically valuable salts, precious metals, and small organic molecules.
