ABSTRACT:
Ozonated water may desirably have the concentration of oxygen present reduced by agitating the water at less than atmospheric pressure to remove dissolved gases. Substantially more oxygen may be removed from the water than ozone by this technique, to provide a product water which has advantages of use in electronic manufacturing operations.
