Apparatus and process for effecting changes in solution concentrations
Abstract
Abstract ACCOMPLISHED BY PLACING IN SPACED RELATIONSHIP TO THE SELECTIVELY PERMEABLE MEMBRANE A SECOND POROUS MEMBRANE PERMEABLE TO THE SOLUTION. WHILE THE APPARATUS AND PROCESS ARE USEFUL IN ALL MEMBRANE SEPARATION SYSTEMS, PARTICULAR UTILITY IS FOUND IN ELECTRICALLY DRIVEN OR PRESSURE-DRIVEN DESALINATION SYSTEMS. THE PRESENT INVENTION RELATES TO AN APPARATUS AND A PROCESS FOR EFFECTING CHANGES IN SOLUTION CONCENTRATION WHEREIN A COMPONENT OF THE SOLUTION IS PASSED THROUGH A SEPARATORY MEMBRANE WHICH IS SELECTIVELY PERMEABLE TO THAT COMPONENT. THIS INVENTION ENHANCES THE EFFICIENCY OF ALL EXISTING MEMBRANE SEPARATION PROCESSES BY REDUCING THE THICKNESS OF THE BOUNDARY LAYERS FORMED AT THE MEMBRANE-SOLUTION INTERFACE. THE REDUCTION IN THICKNESS IS
