Abstract
The present theoretical work explores the effect that the modification of fluid properties (principally viscosity) at the membrane surface plays in determining flux. The first achievement is to show that a limiting flux exists independent of any supposed gelation or osmotic pressure effects.
Secondly, the flux, viscosity, pressure drop equation has been developed by distinguishing between the pressure drop required to drive fluid into the pore entrance and that required to drive fluid through the pore itself. The resulting equations predict the same limiting flux as that referred to above. In addition, a priori predictions of the flux-transmembrane pressure drop relationship can be obtained. Comparisons with experimental data are in progress.
