Abstract: The ozone spray wand is a portable aqueous ozone generator that is adaptable to fit onto garden hoses, backpack sprayers or any other water supply source. The wand uses electrolytic cells to make ozone on-demand. An operator simply pulls the trigger and a solenoid valve starts delivering ozonated water. Embodiments use a rechargeable battery that allows it to operate for 1 hour between recharge cycles. The wand is rated for 500 hours of use which delivers 15,000 gallons of ozonated water.

Abstract: Illustrative embodiments employ catholyte scrubbers to provide higher concentrations of ozone in ozonated water than was possible in prior art systems and methods. Moreover, some embodiments employ scrubbers to increase the efficiency of production of ozonated water by producing such higher concentrations of ozone in ozonated water using the same amount, or less, power than prior art systems and methods. Some embodiments employ scrubbers to enable production of water with higher concentrations of ozone, and/or ozonated water in which the concentration of ozone decays more slowly, as compared to prior art methods.
