For instance this site http://www.awwarf.com/exsums/90607.htm indicates that TCE, PCE, and MTBE are not removed effectively with ozonated water, but are with H2O2 added. If ozonated water is H2O2 water, then there should be no difference. ST: Ozone is extremely reactive relative to hydrogen peroxide, hence it will oxidise substances far more readily (at equal oxygen concentration), accounting for the mentioned phenomenon. It is also this potential, which renders hydrogen peroxide safer, since although two of ozones three oxygen molecules can readily pair to form H2O2, the third molecule is automatically a free radical, until paired and so stabilised as H2O2. Under simple water bubbling conditions, most of the ozone is simply lost to the atmosphere, but it is highly active as it surfaces, though only the hydrogen peroxide has residual anti-microbial effects. Of course, there will be changes to water so treated, besides the addition of increased H2O2, since the mentioned active oxidation will interact with some chlorine etc and it is not unlikely that the water, depending on its chemical condition and temperature, will be optimally oxygenated by the preponderant availability of oxygen, conditions permitting. I trust that this contribution is constructive, rather than argumentive, as Frank seems to fear, though I think he is right about ozone bubbling leading to H2O2.
