US Patent 9205166 Apparatus for generating hydroxl radicals

The invention provides a consumable cartridge for use in a hydroxyl radical generating apparatus, the consumable cartridge comprising: a reactant supply comprising a supply of a substance that reacts with ozone to form hydroxyl radicals; and an ozone supply comprising an ozone generator; wherein the ozone supply is fixed to the reactant supply. By supplying both a reactant supply and an ozone generator in the same consumable cartridge, maintenance operations on an associated base unit in a hydroxyl radical generating system can be minimized.
