Abstract
A system and method for generating high concentration ozone by introducing a high purity oxygen (99.995% or greater purity) into a silent discharge type ozone generator. Another high purity gas (99.99% or greater), is mixed with the oxygen before the gas is introduced into the ozone generator. By this process, high concentration ozone is generated such that the ozone concentration does not decrease with time. The highest ozone concentrations are maintained when the non-oxygen gas makes up between 1% and 10% of the volume content of the gas mixture introduced in the ozone generator.
