Claim:
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.
