Desalination using reverse osmosis membranes has become very popular for producing fresh water from brackish and sea water. Concentration polarization occurs in any pressure driven membrane separation process. It describes an increase in the concentration at the membrane wall due to the rejection of ionic species transported there by the convective flux. Accurate prediction of concentration polarization (CP) phenomenon is critical for properly designing reverse osmosis GO) processes because it enhances transmembrane osmotic pressure and solute passage, as well as surface fouling and scaling phenomena. Membrane life time and permeate flux, however, are primarily affected by the phenomena of concentration polarization and fouling at the membrane surface. This paper aims to investigate the effect of the following parameters on concentration polarization phenomenon such as; feed specifications (flow rate and concentration), operating conditions (feed pressure and temperature) and Membrane dimensions (length and diameter).
