Abstract:
A fluid treatment apparatus for treating a fluid comprises an electrochemical cell having fluid orifices to receive and release fluid, and a fluid passageway connecting the orifices with a water-splitting ion exchange membrane is exposed to the fluid in the passageway. First and second electrodes are positioned about the membrane. The apparatus also comprises a controller to control and operate a power supply and valve system. The power supply supplies a current to the first and second electrodes at sufficiently high current density to result in bacteriostasis, deactivation, or a reduction in the microorganisms in the fluid. The controller can also operate a set of cells to deionize fluid and regenerate the cells.

Abstract:
A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode endplates held apart from each other by a pair of supports such that the supports enclose opposing sides of the endplates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

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.
Abstract:
A chlorine generator cell (10) contains components that require physical isolation between the anode compartment (20), cathode compartment (30), and outside environment. The cell (10) also contains a membrane (50) that provides selective electrical conductivity between the anode compartment (20) and cathode compartment (30). The cell (10) consists of a series of pipe fittings that allow access to the interior of cell (10) for placement of water and salt to generate chlorine. The anode stem (71) and cathode stem (81) located outside of cell (10) are connected to a power supply (91). Power supply (91) may be further connected to a power controller (92) that allows for adjustment of the energy output of power supply (91) to the optimum energy level, thus the desired chlorine output. This invention provides a chlorine generator that is portable, yet is allows for expanded size with additional pipe fittings as needed. Furthermore, this invention allows multiple to infinite chlorine output levels with a single cell (10).
Abstract:
A mediated electrochemical oxidation process and apparatus are used to process biological and organic materials to provide hydrogen and oxygen for use as fuel in numerous types of equipment. Waste materials are introduced into an apparatus for contacting the waste with an electrolyte containing the oxidized form of one or more reversible redox couples, at least one of which is produced electrochemically by anodic oxidation at the anode of an electrochemical cell. The oxidized species of the redox couples oxidize the organic waste molecules and are themselves converted to their reduced form, whereupon they are reoxidized and the redox cycle continues until all oxidizable waste species have undergone the desired degree of oxidation. The entire process takes place at temperatures to avoid any possible formation of either dioxins or furans. The oxidation process may be enhanced by the addition of ultrasonic energy and/or ultraviolet radiation.
