Abstract
In the reported experiments, initial time unsteady stirred ultrafiltration studies of solvent flux and solute retention have been carried out with two proteins, BSA and ovalbumin, and membranes XM 100 A and XM 300, both being partially permeable to the solutes. It is shown that the time to attain a steady state solvent flux depends primarily on the applied pressure and solute bulk concentration with minor contributions from membrane permeability and solute size. Initial time solute retentions are shown to be considerably lower than the steady state values reported in membrane manufacturers' catalogs. The solute retentions depend on applied pressure and bulk concentration in a manner suggested by Blatt, et al.
