The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle
The invention relates to a method for purifying water by dissolving one or more soluble metal salts in the water to provide corresponding metal ions, by dissolving hypohalite into the water, and by regulating the residence time, and thus hypohalite concentration in the device using a venturi nozzle disposed between the metal generator and the hypohalite generator.

What is claimed is: 1. An apparatus for purifying water, comprising: an inlet and an outlet; a metal generator, having an inlet in fluid communication with the inlet of the device, and a first outlet and a second outlet, and adapted to provide concentrations of one or more metals to the water; a halogen generator, having an inlet in fluid communication with the first outlet of the metal generator, and having an outlet, and adapted to provide concentrations of halogen to the water; a venturi nozzle, having an inlet in fluid communication with the second outlet of the metal generator, which is in fluid communication with outlet of the halogen generator, and having an outlet in fluid communication with the outlet of the device. 2. The apparatus of claim 1, wherein the metal generator provides bactericidally, algaecidally, fungicidally, or viricidally effective concentrations of metal to the water. 3. The apparatus of claim 1, wherein the metal comprises one or more metal ions selected from the group consisting of silver ion, copper ion, zinc ion, and mixtures thereof. 4. The apparatus of claim 1, wherein the metal ions comprise silver ion and copper ion. 5. The apparatus of claim 1, wherein the metal generator comprises metallic material. 6. The apparatus of claim 5, wherein the metallic material comprises metallic silver. 7. The apparatus of claim 1, further comprising a housing that encloses the metal generator and the halogen generator, and configured to: direct at least a portion of the water through the metal generator; direct a portion of the water through the halogen generator; direct another portion of the water through the venturi nozzle; and direct the treated water out of the housing via the outlet. 8. The apparatus of claim 1, further comprising a pressure relief valve. 9. The apparatus of claim 1, further comprising a control valve disposed between the metal generator and the halogen generator, adapted to regulate the volume of water flowing from the metal generator and into the halogen generator. 10. The apparatus of claim 9, wherein said control valve further regulates the flow of water through the venturi nozzle. 11. The apparatus of claim 10, wherein fluid communication between the halogen generator and the venturi nozzle is provided by a flow path having an inlet associated with the halogen generator and an outlet associated with the venturi nozzle, and wherein the control valve regulates the pressure drop across the flow path inlet and outlet. 12. The apparatus of claim 11, wherein the flow path comprises a tube connecting the halogen generator and the venturi nozzle. 13. The apparatus of claim 9, further comprising a control valve disposed in a flow path between the halogen generator and the venturi nozzle. 14. The apparatus of claim 1, wherein the first outlet of the metal generator is in fluid communication with a metal generation chamber bypass, and is adapted to allow flow of untreated water from the metal generating chamber to the halogen generator, and wherein the second outlet of the metal generator is in fluid communication with a metal generating chamber, and is adapted to allow flow of water having increased metal concentration from the metal generating chamber to the inlet of the venturi nozzle. 15. The apparatus of claim 1, further comprising a control valve disposed in a flow path between the halogen generator and the venturi nozzle. 16. The apparatus of claim 1, wherein the first outlet of the metal generator is in fluid communication with a metal generating chamber, and is adapted to allow flow of water having increased metal concentration from the metal generating chamber to the halogen generator, and wherein the second outlet of the metal generator is in fluid communication with a metal generation chamber bypass, and is adapted to allow flow of untreated water from the metal generating chamber to the inlet of the venturi nozzle. 17. The apparatus of claim 1, wherein the inlet of the halogen generator in fluid communication with the first outlet of the metal generator is located at a distance below the outlet of the halogen generator. 18. The apparatus of claim 17, wherein the inlet of the halogen generator comprises the outlet of a tube extending from the first outlet of the metal generator to a point below the outlet of the halogen generator and near the bottom of the halogen generator. 19. A method for purifying water, comprising passing the water through the apparatus of claim 1. 20. A water purification system, comprising a body of water to be purified, and the apparatus of claim 1 in fluid communication with the body of water, such that at least a portion of the body of water is directed into the apparatus. 21. The system of claim 20, wherein at least a portion of the water directed into the apparatus is returned to the body of water. 22. The system of claim 21, wherein the body of water comprises a pool, hot tub, or spa.
