The flux displayed a typical asymptotic behaviour with increasing transmembrane pressure, indicative of concentration polarization. In the polarized pressure-independent region, flux was significantly affected by velocity and feed concentration; temperature had a small positive effect. The Leveque and the Grober laminar flow models underpredicted the experimental flux. The model was mofified to include a concentration-dependent diffusivity term and to account for non-Newtonian rheological behaviour at high concentrations. The correlation which best fitted the data was Sh=0¡P087(Re) 0¡P64 (Sc) 0¡P33 . ? 1987. |
