Patent ID: 7736494

Claim:
An apparatus for delivering a measurable absorbed-dose of ozone to a measured amount of fluid, comprising: a) an ozone generator that manufactures an ozone/oxygen admixture, and controls the concentration of ozone within the ozone/oxygen admixture; b) a gas flow meter that controls and measures the amount and flow rate of the ozone/oxygen admixture delivered to a gas-fluid contacting device; c) a gas-fluid contacting device including at least one variable pitch device, each variable device including a base having a flange extending around an open upper end thereof, a cover closing the open upper end of said base, and a plurality of bolts extending through the cover and flange to removably attach the cover to the base, the base and the cover together defining an enclosed chamber having an inlet end and an outlet end and that interfaces an ozone/oxygen admixture with a fluid, wherein a gas exit port and a fluid entrance port are disposed in the cover proximate said inlet end, a gas inlet port is disposed in the cover proximate said outlet end, and a fluid drain port is disposed in said base at proximate said outlet end; d) a fluid pump that controls and measures an amount of the fluid and a flow rate of the fluid entering a the gas-fluid contacting device; e) a variable pitch platform for supporting the at least one variable pitch device, wherein said variable pitch platform includes a mechanism for adjusting the pitch of the at least one variable pitch device relative to a horizontal base of said platform, said variable pitch platform cooperating with the fluid pump to control the time during which the ozone/oxygen admixture interfaces with the fluid in the gas-fluid contacting device; f) an inlet ozone concentration monitor that measures the concentration of the ozone/oxygen admixture entering the gas-fluid contacting device; g) an exit ozone concentration monitor that measures the concentration of an ozone/oxygen admixture exiting a gas-fluid contacting device; and h) a data acquisition device that cooperates with the gas-fluid contacting device, the ozone generator, the gas flow meter, the fluid pump, the variable pitch platform, the inlet ozone concentration monitor and the exit ozone concentration monitor, to determine: i. the elapsed-time during that the ozone/oxygen admixture interfaces with the fluid in the gas-fluid contacting device; ii. the amount of ozone in the ozone/oxygen admixture that is delivered to the gas-fluid contacting device; iii. the amount of ozone absorbed by the amount of fluid, within the gas-fluid contact device; and iv. the amount of ozone remaining in the ozone/oxygen admixture exiting the gas-fluid contact device; and wherein all ozone-contacting surfaces of said apparatus are constructed of material that is ozone-inert.
