Various states and Federal agencies have found ozone generators or lighting air generators put out ozone far in excess of legal limits. One report by the University of Tulsa found room concentration of 2 ppm, which is fifteen times the legal limit and twice the human tolerance level. Pressure - As pressure increases, more gas is forced into the liquid. At higher temperatures, water tries to release gas rather than absorb it. Bubble Size - As a gas is broken down into more and smaller bubbles, the total surface area of the bubbles increases, thus increasing the area for interaction of ozone and water.
Ozone is produced on site.
There are no dangerous chemicals to transport, store, or handle. Perhaps even more important, the chance of overdosing with dangerous and hazardous chemicals is limited. In the oxidation process, ozone ruptures the cellular membrane of microorganisms and disperses the bacterial cytoplasm into solution, thus making reactivation impossible. This process takes place in about two seconds. Chlorine must first diffuse through the bacterial cell wall after which oxidation of the bacterium's enzymes by hypoclorous ions causes death.
