The productive RO membrane shouldoffer simultaneously high solute rejection, waterpermeability, chemical stability and good chlorineresistance particularly for aqueous acetate and aromatic Polyamide group ofpolymers are known as two best polymer materialsfor Reverse Osmosis (RO) applications till date [1].Cellulose acetate (CA), cellulose triacetate (CTA) andcellulose acetate-cellulose triacetate blend (CAB)membranes are prepared generally in asymmetricform and hence give relatively lower flux comparedto the new generation thin-film Composite (TFC)membranes.
