Analysis of an ultrafiltration model: Influence of operational conditions

► High TMPs and low CFVs, resulted in a higher contribution of the gel layer resistance. ► The Ro and the gel layer resistance decreased with an increase in temperature. ► Multiple regression allowed to obtain JPss and rc/cg as a function of TMP and CFV. ► The best fittings were obtained for JPss at low concentrations for both membranes.
