The concentration polarization model has been applied to analyze the permeate flux of hollow-fiber membrane ultrafiltration. Comparison of theoretical prediction with experimental data has been made under various transmembrane pressures, feed velocities, and solution concentrations. Both theoretical prediction and experimental results show that average permeate flux increases as transmembrane pressure or feed velocity increases, but decreases when solution concentration increases. 24 refs., 9 figs.
