The objective of this work is to study the separation performance of a tubular TiO2 ceramic nanofiltration membraneoperate at low pressures (2 bar), and the parameters that would affect the membrane rejection behavior, such as theions valences, ions type, transmembrane pressure (TMP) values, and membrane zeta-potential. The membrane wasused to desalinate water samples containing NaCl, NaNO3, and Na2SO4 in single and tertiary salts solution. Therejection of ions solutions took the following trend: R of sulphate (SO42-) > R of nitrate (NO31-)>R of chloride (Cl1-)>R ofsodium (Na1+). The highest SO42-rejection was about 62%, the highest NO31-rejection was about 51%, the highest Cl1-rejection was about 42%, and highest Na1+ rejection was about 37%.
