Abstract: | Asymmetric PSf UF membranes were prepared at different shear rates which were 103.Ss-1, 129.3s-and 258.7s-' to investigate the influence of different shear rate on the membrane structure and performance of asymmetric membrane by using sodium chloride solution. The experimental data was modeled based on the pore flow, solution-diffusion mechanisms and the extended Nemst-Plank equation. The Spiegler -Kedem membrane transport model was used to evaluate the membrane parameters such as reflection coefficient and solute permeability, P5 • The fine structural details of the ultrafiltration membrane were evaluated in terms of effective pore radius rp and ratio of effective membrane thickness to membrane porosity. The measurement was conducted using steric-hindrance pore (SHP) model. |
