The CEDI process takes advantage of a combination of mixed resin, selectively permeable membranes, and an electric cost, supplying steady flow (solution and squander focus) and constant regeneration. Drinking water enters each the resin portion as well as the squander (focus) portion. Because it passes in the resin, it's deionized to become solution water. The resin functions for a conductor enabling the electrical probable to travel the captured cations and anions through the resin and appropriate membranes for focus and removal inside the waste drinking water stream.
