Ultrafiltration uses a membrane with a Molecular Weight Cutoff range between 1000 and 1,000,000 Daltons. It is used primarily to concentrate solutions of macromolecules such as proteins while permitting the removal of low molecular weight solutes. The rejection properties of the membrane depend are related to operating variables such as system pH, ionic strength, hydrodynamics, permeate flux and also strongly dependent on fouling.
