Abstract
Apparatuses and processes are described for transferring electrolytes from one electrolytically conducting solution to another, said apparatus comprising a pair of spaced electrodes; at least one pair of spaced electrolytically conducting barriers between said electrodes, one of said barriers having a transport number for ions of one sign substantially greater than that of said solutions and of the other barrier, means for applying a substantially direct current electrical potential between said electrodes in a direction to cause electrolyte to the transferred out of the space between said barriers; a plurality of fluid permeable tubules between said barriers; means for introducing fluid into at least one end of such tubules; and means for withdrawing fluid from the space between said barriers.
