Abstract

Using Donnan Steric Partitioning Model (DSPM), the data for the rejection of four salts having common co-ion (LiCl, NaCl, KCl, Na 2SO 4) were obtained and they show the characters of the polyethersulfone (PES) nanofiltration (NF) membrane in terms of three parameters: an effective pore radius ( r p), the ratio of effective thickness over porosity (λ/ A k) and an effective charge density ( X). Good agreement between experimental data and prediction data using the three parameters mentioned above was obtained. A theoretical model was developed to predict the transport performance of electrolyte through the hollow fiber composite NF membrane. The model prediction is in good agreement with experimental results based on the method by modern numerical solution.
