The use of ceramic membranes has recently been gaining interest among many researchers. However, due to the complexity of the ceramic membrane, there is a need to investigate its transport behavior during the separation process. Ceramic NF membranes' filtration efficiency depends on steric (sieving) and electrical (Donnan) effects. Through these combination, there are may be high rejection rates of small uncharged solutes while the surface electrostatic properties allow monovalent ions to be reasonably well transmitted through with multivalents ions mostly retained. Transport equations used in this study are based on the extended Nernst-Planck equation, which is the fundamental relationship governing the transport of ionic species through membrane pores. The mass transfer in ceramic membrane will e more complicated compared to that in polymeric membranes due to the membrane surface charge effect.
