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. {\^A}{\copyright} 2021 Techno-Press, Ltd.}, issn = {20058624}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85105100793&doi=10.12989\%2fmwt.2021.12.2.059&partnerID=40&md5=ffb89f0c1da85d210daadb8b4041c2cf}, author = {Qadir, D. and Nasir, R. and Mukhtar, H. and Uddin, F.}, keywords = {Calcium chloride; MATLAB; Nanofiltration; Sodium chloride, Average relative error; Concentration polarization; Extended Nernst-Planck equation; Membrane characterization; Negative surface charges; Performance prediction; Single-salt solutions; Sodium chloride (NaCl), Nanofiltration membranes} }
