Abstract

The unsteady-state permeate flux response to a step change in the transmembrane pressure in a stirred ultrafiltration cell was studied. The changes in the gel-layer concentration and gel-layer growth, with the change in the transmembrane pressure were studied. Metal solutions were prepared in a polymeric solvent, and the dynamics of the operating parameters on this process were studied. The process, a hybrid process called Polymer Enhanced Ultrafiltration, (PEUF) was modeled mathematically and validated using experimentation for the change in the transmembrane pressure and concentration of the polymeric solvent added. The permeate flux was modeled using gel-polarization model and first principles model which was solved using MATLAB’s PDE and ODE solver subroutines.
