Inactivation of Giardia muris using ozone and ozone-hydrogen peroxide

摘要

The pohosphate-carbonate buffer s ystem had significantly greater (P<= 0.05) inactivation of G.muris cysts than that observed in the phosphate buffer-peroxide system where ozone was completely decomposed in less than 120 s. Consequently, the design of ozone disinfection processes should maintain ozone residual for disinfection prior to the addition of hydrogen peroxide for the oxidation of other compounds.
