Ultrafiltration Modeling Allowing for Axial Dispersion in a Solution under Purification

Resumo

Formulas for ultrafiltration operating and geometric parameters that take into account the longitudinal diffusion of solute molecules in a solution under treatment have been derived based on differential equations of material balance. The effect of longitudinal diffusion on the concentration of solute molecules in the permeate and the retentate in comparison with plug flow and perfect mixing conditions has been evaluated.
