Results showed that the NFDK membrane had a negative surface charge and had a higher observed rejection of 93.65 for calcium (Ca2+) ion and 78.27 for sodium (Na+) ions. Prediction of rejection for aqueous solutions of both salts was made using Donnan Steric Pore Model based on Extended Nernst-Planck Equation in addition to concentration polarization film theory. A MATLAB program was developed to execute the model calculations. Absolute Average Relative Error ( AARE) was found below 5 for real rejection of the NFDK membrane. This research could be used successfully to assess the membrane characterization parameter using a proposed procedure which can reduce the number of experiments. © 2021 Techno-Press, Ltd.
