Abstract
Reverse osmosis separation of aqueous NaCl, MgCl2, Na2SO4 and MgSO4 solutions were carried out using CA membranes and 3 composite membranes. Membrane constants were calculated by the Spiegler-Kedem's transport model. Hydraulic permeability decreases with increase of concentration of solute in feed, only depends upon osmotic pressure on the surface of the membrane but not upon salt spiecies. Distribution coefficient of salt to CA measured separately was dependent upon concentration of salt in feed and salt spiecies. Diffusion coefficient of each salt in CA (90) membrane calculated decreases with osmotic pressure on the surface of the membrane up to 1 MPa but almost are constant beyond that pressure.
