Nanofiltration membranes review: Recent advances and

Jan 15, 2015 · Nanofiltration (NF) membranes have come a long way since it was first recognized in the late 80's. With properties in between ultrafiltration (UF) and reverse osmosis (RO), NF membranes possess pore size typically of 1 nm which corresponds to molecular weight cut-off (MWCO) of 300–500 Da. NF membranes in contact with aqueous solution are also slightly charged due to the dissociation …
