The CEDI technique employs a combination of mixed resin, selectively permeable membranes, and an electric demand, delivering constant stream (solution and squander concentrate) and ongoing regeneration. Water enters equally the resin segment and the squander (concentrate) part. Mainly because it passes through the resin, it really is deionized to be item h2o. The resin acts as a conductor enabling the electrical opportunity to push the captured cations and anions with the resin and proper membranes for concentration and removal in the squander h2o stream.
