Filed:

Dec 22, 2000

Appl. No.:

09/748103

Inventors:

William Holt - Seabrook TX 77586
John V. Kraft - Waller TX 77484

International Classification:

C02F 146

US Classification:

210748, 210764, 210 95, 204273, 204280, 204286, 204287, 205742

Abstract:

A method and apparatus turbulently exposes water flowing through a water system to a plurality of electrodes of an ion generator and provides a self-contained tank through which water flows. The generally cylindrical containment tank includes a tangential inlet pipe and an elliptical base having an outlet pipe. An aspect ratio, inlet pipe diameter versus containment tank diameter, is defined to achieve optimum ionization. A tank cover serves as the non-electrical conducting head for a plurality of electrodes which extend downwardly from the underside of the cover. The electrodes are functionally configured to maximize water flow between them. The rate of water flow within the containment tank is defined such that residence time of flow within the tank likewise optimizes water ionization. A sight glass allows for visualization of the container contents, and in particular anode wastage or wear, during operation.

Abstract:

A method and apparatus for turbulently exposing water flowing through a water system to a plurality of electrodes of an ion generator and having a self-contained tank through which water flows is provided with an inlet pipe that directs water flow between the electrodes. A tank cover serves as a non-electrical conducting head for the plurality of electrodes that extend downwardly from the underside of the cover. The electrodes are functionally configured to maximize water flow between them. Following the flow of water between the electrodes, a double vortex of water flow is created along one wall of the tank. A sight glass allows for visualization of the container contents, and in particular electrode wastage or wear, during operation.

Appl. No.:

11/078273

Inventors:

William Holt - Seabrook TX, US
John V Kraft - Lipan TX, US

International Classification:

C02F 1/32
C02F 1/467

US Classification:

210 97, 210134, 210192, 210205

Abstract:

A method and system flows water through a water system in proximity to an ion generation device and to a source of ultraviolet (UV) radiation that combines photochemistry principles, heavy metal toxicity, and UV light radiation to form a highly effective combined water disinfection process. Using ion generation and UV irradiation, the method and system synergistically improves the disinfection and bactericidal effects of ion generation or UV radiation working individually by making ion-exposed microorganisms more susceptible and less resistant to the bactericidal effects of UV radiation. The combined method and system of the present invention may include control means such that the method and system can be configured for single pass through, dual pass through or for recirculation such that the order of exposure to the ion generation and UV radiation aspects can be varied or altered. The method and system of the present invention may also be provided with means for controlling the system flow rate, ion generation and UV radiation levels to maximize performance, to minimize energy consumption, and, in some situations, to selectively target certain microorganisms for inactivation.
