Definitions
- the present invention which is drawn to a method and system for increasing the quantity of dissolved gas in a liquid and for optimizing the amount of dissolved gas that remains in solution to a point of use. More specifically, it is an object of the present invention to provide a method and system for increasing the quantity of dissolved ozone in an aqueous solution, and furthermore, for maintaining the dissolved ozone in solution when delivered to a point of use. In this manner, the present invention provides an exceptionally efficient method and system for producing and using high concentration ozonated water.
- pressurized gas conduit (18) is preferably constructed of a material resistant to the deteriorating effects of ozone
- pressurized gas conduit (18) may be constructed of stainless steel, quartz, or a fluo ⁇ nated polymer such as Teflon® PFA or Teflon® PTFE, commercially available from E I DuPont deNemours & Co , Wilmington, DE
- the initial ozone concentration was measured by taking a side stream of ozonated water from the pressurized vessel and using a commercially available sensor to measure the dissolved ozone concentration.
- a second sensor was used to measure the dissolved ozone concentration after the liquid was dispensed through the spray post by collecting the liquid and funneling it to the sensor.
- the percentage ozone remaining in solution was calculated by the formula [O3 finai]/[O3j n ;ti a i]*100, where the symbol [O3] stands for the concentration of ozone dissolved in water.
- atomization was achieved by causing a stream of atomizing gas to impinge with a stream of ozonated water.
