    The behavior of reverse osmosis membranes against salts separation from salty water during desalination process depends mainly on ionic size, diffusivity and feed concentration of the solute. Here we studied the mechanism of different solutes transport through a commercial BW-TFC membrane using NaCl, CaCl2, Na2SO4, and MgSO4 as feed solutions at different initial feed concentrations (1000, 2000, 5000, 10000 mg/l) and two applied pressures (two and three folds of each salt osmotic pressure). In addition, the membrane transport parameters were investigated using two groundwater samples as feed solutions. The membrane transport parameters; solute transport parameter (DAM/Kδ) and mass transfer coefficient (k), useful for the prediction of the membrane performance, have been calculated by fitting the graphical method to the experimental results.
