Aqueous - Nanofiltration Membrane

Nanofiltration membrane technology separates solution to the molecular level. It rejects various larger-size organics, including dyes and sugars, and also has a strong rejection of divalent ions over monovalent ions. Nanofiltration generally uses spiral wound membranes configured in a similar design as reverse osmosis. Some applications include partial softening of feed water, removal of contaminants from water or acid streams, and pretreatment for reverse osmosis or other high purity systems.
