FLOW DE-IONIZATION USING INDEPENDENTLY CONTROLLED VOLTAGES

摘要

An embodiment is a method and apparatus to provide de-ionization. A plurality of cylindrical-shaped conductive membranes are placed in a feed channel having a feed flow with a first flow direction. Each of the conductive membranes encloses a concentration channel having a second flow direction and an electrode positioned inside the conductive membrane. A voltage distribution network coupled to the conductive membranes provides independent voltages across the channels to cause movement of ions in the feed and concentration flows toward the electrode.
