    Abstract: A compact water purification device which is made of concentrically mounted components is provided according to the invention. An anode with a fluid passageway through its interior to provide an anode fluid path is used. A anionic support member is concentrically mounted about the anode and a anionic membrane is mounted to the exterior of the anionic support member. A first fluid passageway between the anionic membrane and the anode is provided. A bead is concentrically mounted about the anionic support member to provide a water purification path and to hold the ion exchange resins therein for contact with the water in the water purification path. Fluid communication is maintained between the water purification path and the anionic membrane. A cationic membrane is concentrically mounted about the exterior of the bead box. Fluid communication is provided between the water purification path and the cationic membrane. A cathode is concentrically mounted about the cationic membrane. A passageway is provided between the cationic membrane and the cathode to define a second fluid passageway. An anolyte waste stream through said anode fluid path and through said first fluid passageway is provided as well as a catholyte waste stream. The resulting device provides a compact effective water purification unit.

    Abstract: An electrochemical extraction method comprises establishing a cell of the form working electrode: flowing aqueous electrolyte solution: second electrode. The working electrode includes an ion exchange material and the second electrode may include ion exchange material. D.C. potential is applied to the cell to adsorb ions onto the working electrode and cell polarity is subsequently reversed to elute the adsorbed ions.The cell is separated by a cell divider, e.g. in the form of an ion selective membrane, into first and second electrolyte compartments and the solution is passed through the compartment adjacent the working electrode to effect adsorption and, where the second electrode includes ion exchange material, solution is passed through the compartment adjacent the second electrode to effect desorption.

    Abstract: A liquid treatment process is described for sequential removal of ionic species of progressively decreasing ionic strength without precipitation or “scaling.” An embodiment of the invention includes dual electrodeionization operations. The first electrodeionization operation is performed at a voltage calculated to remove strongly ionized species such as calcium and magnesium from the feed water without scaling. The product of the first electrodeionization operation is then subjected to a second electrodeionization operation. The second electrodeionization operation is performed at a voltage greater than the first electrodeionization operation, and is designed to remove more weakly ionized species such as silica and atmospheric carbon dioxide. The danger of precipitation or “scaling” normally present during electrodeionization of weakly ionized species is not present in this invention, because the strongly ionized species responsible for scaling at higher voltages have already been removed from the feed stream through the first electrodeionization operation. More than two successive electrodeionization operations may be performed if desired. Multiple electrodeionization operations may occur in a single electrodeionization stack or in multiple electrodeionization stacks.
