CHARGED ULTRAFILTRATION MEMBRANE DEMINERALIZATION OF BRACKISH WATERS FOR IRRIGATION

THE PROPOSED FEASIBILITY RESEARCH IS TO USE A UNIQUE GRAFTI ING TECHNIQUE TO MODIFY MEMBRANE MATERIALS IN SUCH A WAY AS TO RENDER THEM USEFUL FOR SPECIFIC WATER TREATMENT SITUATIONS. THE WORK WILL SPECIFICALLY FOCUS ON THE DEVELOP MENT OF THE GRAFTING TECHNIQUE FOR POROUS MEMBRANE MATERIAL S. THE TECHNIQUE WILL BE DEMONSTRATED BY THE GRAFTING OF CHARGED MONOMER AND POLYMERS ONTO SEVERAL MATERIALS INCLUD ING POLYSULFONE, CELLULOSE ACETATE AND POLYAMIDE. SUCCESSFULMEMBRANES WILL EXHIBIT ENHANCED REJECTIONS OF MULTIVALENT IONS AND HIGH FLUX LEVELS AT LOW OPERATING PRESSURES.
