Abstract

PURPOSE: To regenerate an ion exchange membrane, activity of which has been reduced owing to contamination by hardly permeable org. ions, to the original state completely within a short time by means of reverse transmission, by substituting at least a part of conc. water with an aq. salt soln. free from org. ion.
