Water Membrane
Nanofiltration membranes, like reverse osmosis membranes, have a thin-film composite layer (1 m) on top of a porous layer (50 to 150 m) for tiny ion selectivity. NF membranes reject multivalent salts and uncharged solutes but allow monovalent salts to pass through. They can also operate at lower pressures than reverse osmosis membranes, making them ideal for achieving the best flow-to-rejection ratio.
