Research abstract
THIS RESEARCH RELATES TO IMPROVING THE FIELD PERFORMANCE OF REVERSE OSMOSIS WATER PURIFICATION UNITS THROUGH IMPROVING THE PROCEDURES USED FOR MEMBRANE ELEMENT CLEANING. THE PROPOSED RESEARCH INVOLVES OBTAINING A BETTER UNDERSTANDING OF WHY MEMBRANE PERFORMANCE DEGRADES AFTER CLEANING BY CURRENT PROCEDURES, AS WELL AS EXPLORING THE FEASIBILITY OF REPLACING THESE CHEMICAL METHODS WITH AN ESSENTIALLY MECHANICAL TECHNIQUE. THE APPROACH INVOLVES USING THE PERMSELECTIVITY OF SUGARS AND SECONDARY ELECTRON IMAGING TO STUDY CHANGES IN THE MORPHOLOGY OF MEMBRANE FILMS THAT RESULT FROM FOULING AND SUBSEQUENT CLEANING. A LARGE PORTION OF THE PROPOSED EXPERIMENTS INVOLVES DEVELOPING TECHNIQUES FOR CLEANING MEMBRANES IN SITU ULTRASONICALLY.
