Abstract The effects of operating conditions on the permeate flux for the ultrafiltration of an aqueous solution of dextran T500 in hollow-fiber membrane modules have been investigated based on the modified gel-polarization model. It is found in this study that the present modified model successfully correlates the experimental results obtained under a lower transmembrane pressure while the conventional model only applies to operation under a high transmembrane pressure. It is believed that this model would be suitable for most membrane ultrafiltration systems.
