Nanofiltration is the separation level between reverse osmosis and ultrafiltration. NL NF-2 membrane is suitable for the removal of organic compounds and partially softening surface water and groundwater, as well as reuse of reclaimed water, industrial water production and removal of pesticides/organic matter of the waste water. Compared with NF-1 membrane, NF-2 has higher water flux, saving energy costs, and is ideal for operating systems that require higher water production.
