Abstract: An electrode for use in a deionization apparatus includes a conductive material that is in a granular form and is arranged in a layer that is defined by a first face and a second face. The electrode includes a substrate that is disposed against the first face, and a first member that is disposed against the second face and is formed to permit a fluid to pass through the first member and into contact with the granular conductive material to permit absorption of ions by the granular conductive material.

Abstract: A system for controlling the operation of conductive plates immersed in an aqueous solution, such as in water treatment applications. The system allows independent control of the current sourced or sunk by each of a plurality of plates. The system also allows each plate to be placed in a high-impedance state in which no appreciable current is sourced or sunk by the system. A plate or a group of plates is controlled by a control module which interfaces to a central controller such as a personal computer or a programmable logic controller. Multiple control modules can be added to a system to support multiple plates, each of which can be controlled individually from the central controller. Each control module is also capable of sensing voltage and current at its corresponding plate and providing that information to the central controller.
