NF-1 Membrane

Nanofiltration is the separation level between reverse osmosis and ultrafiltration.  Compared with conventional reverse osmosis membrane, NL NF-1 membrane has high selectivity for divalent and polyvalent ions in water, and its operating pressure is less than 1/3 that of conventional brackish water reverse osmosis membrane. Nanofiltration can be used to soften water and effectively remove total organic carbon (TOC), low molecular weight compounds, bacteria, and heavy metal pollutants in water with high energy efficiency.  NF-1 is suitable for wastewater reuse and industrial water treatment applications. NF-1 has a higher rejection than NF-2 membrane.
