Abstract
A portable oxidant generator for generating a chlorine or chlor-oxygen solution suitable for sterilizing contaminated drinking water, thereby providing a water disinfection system and potable water. The oxidant generator includes an electrolytic chamber and a power supply or source. The chamber holds a salt brine solution such that the solution is in contact with an anode and cathode included in the chamber. The power supply provides electrical charge that is passed between the anode and cathode through the salt brine solution. In the preferred embodiment of the present invention, a combination manual pump/switch is activated and injects electrolyte into the cell chamber and electrolyzes the solution. In one embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes a gas pressure within the cell chamber thereby forcing the freshly generated oxidant solution from the cell. In another embodiment, as electrolysis proceeds, hydrogen gas is liberated and causes gas pressure within the sealed cell chamber which acts against a spring loaded piston thereby increasing the chamber volume to minimize pressure buildup, and to maintain the electrolyte in contact with the anode and cathode throughout the electrolysis process irrespective of the orientation of the device. When electrolysis is complete, an electric valve is actuated that allows the freshly produced oxidant to be discharged in to the drinking container to provide disinfection and render the water potable.
