Patent ID: 8323563

Claim:
An on-demand ClO 2 generator, comprising: a solid reagent bound medium in a first container, said first container having an inlet and an outlet for discharging a ClO 2 solution; a complementary reagent solution in a second container separate from said first container, wherein said first container and said second container are coupled, wherein said second container is situated upstream of said first container, and wherein the complementary reagent solution is stored in isolation of said solid reagent bound medium until generation of said ClO 2 solution is demanded; a pressure source situated upstream of said complementary reagent solution; and at least two valves for selecting between a first position for storage, wherein said solid reagent bound medium in said first container is isolated from said complementary reagent solution in said second container, and a second position for demanding, wherein said complementary reagent solution from said second container is forced under pressure through said inlet and through said reagent bound medium in said first container, and wherein said ClO 2 solution is generated and discharged through said outlet only during periods when said at least two valves are in said second position, wherein said at least two valves comprise a first valve situated between said first container and said second container and a second valve situated at said outlet of said first container.
