ANALYSIS OF TRANSPORT IN A PRESSURE-DRIVEN MEMBRANE SEPARATION PROCESS.

The analysis of transport through a membrane in a pressure-driven membrane separation process need not include assumptions about the microstructure of the membrane. An analysis of transport is presented which interprets phenomenological relations in terms of the strengths of physicochemical interactions in the solute-solvent-membrane material system. No assumptions about the membrane microstructure are made. The results of this analysis are compared with the results of an analysis of transport through finely porous membranes.
