  • Patent number: 6736966
    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.
