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. date: 2021 publisher: Techno-Press official_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 id_number: 10.12989/mwt.2021.12.2.059 full_text_status: none publication: Membrane and Water Treatment volume: 12 number: 2 pagerange: 59-64 refereed: TRUE issn: 20058624 citation: Qadir, D. and Nasir, R. and Mukhtar, H. and Uddin, F.
