Method for purifying water
View Patent ↗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.
1. A method for purifying water comprising the steps of:
providing a water purifying system comprising: a) an inlet for entry of water; b) a metal-generating media adapted to contact at least a portion of the water in a system and provide concentrations of one or more metals to the water; and c) a halogen-generating media adapted to contact at least a portion of the water in the system and provide concentrations of one or more halogens to at least a portion of the water, wherein the metal-generating media and the halogen-generating media are in fluid communication with one another;
providing a flow path between b) and c);
carrying at least a portion of water through said system via the flow path;
creating a pressure drop; and
drawing water from the halogen-generating media into the flow path;
wherein an exit outlet is in fluid communication with the flow path, the exit outlet adapted to allow water to exit the water purifying system, whereby at least a portion of the water exiting the system is purified.
2. The method of claim 1 , wherein the metal-generating media and the halogen-generating media are contained in a housing.
3. The method of claim 2 wherein at least a portion of the water entering the system flows through the metal-generating media, flows through the halogen-generating media, and enters the flow path to exit the system.
4. The method of claim 2 , wherein at least a portion of the water entering the system by-passes the metal-generating media, flows into the halogen-generating media, and enters the flow path to exit the system.
5. The method of claim 2 , wherein at least a portion of the water entering the system by-passes both the metal-generating media and the halogen-generating media and enters the flow path to move water from the halogen-generating media to exit the system.
6. The method of claim 2 , wherein at least a portion of the water entering the system flows through the metal-generating media, enters the flow path to move water from the halogen-generating media into the flow path to exit the system.
7. The method of claim 2 , wherein the system is selected from the group consisting of: a pool and a spa.
8. The method of claim 1 , wherein at least a portion of the water entering the system is directed to:
(1) enter the metal-generating media and flow into the halogen-generating media;
(2) by-pass the metal-generating media and flow into the halogen-generating media;
(3) by-pass both the metal-generating media and the halogen-generating media and enter the flow path;
(4) enter metal-generating media and enter the flow path; or
(5) some combination thereof.
9. The method of claim 1 , wherein the system is selected from the group consisting of a pool and a spa.
10. A method for purifying water in a system adapted to receive water comprising the steps of:
providing water to the system;
providing a metal generator in communication with the water;
directing at least a portion of the water into a metal generator;
providing a halogen generator in communication with the water and the metal generator;
directing at least a portion of the water into a halogen generator;
directing at least a portion of the water into a flow path adapted to create a pressure drop to move water from the metal generator or halogen generator into the flow path; and
directing at least a portion of the water out of the system.
11. The method of claim 10 , wherein the system is selected from the group consisting of pools and spas.
