ABSTRACT:
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.
