"WebTo bring about a proper disinfection and oxidation, the ozone concentration must be as high as possible. The prediction of ozone solubility is more complicated than for other gasses, because ozone solubility is influenced by several factors, such as temperature, pH and dissolved matter. This is a consequence of the instability of ozone in water. " - Ph of ozone
