Nanofiltration
uses a membrane with a Molecular Weight Cutoff range between 150 and 1000 Daltons. It functions as a loose or
leaky RO membrane which permits water, univalent ions
and small molecules like simple sugars to pass through.
The rejection properties of the membrane are intimately
related to operating variables such as system pH, ionic
strength, hydrodynamics and permeate flux.
