H2O2 is a strong oxidant (standard potential 1.80 and 0.87V at pH 0 and 14, respec-tively) and its application in the treatment of various inorganic and organic pollutants is well established. Numerous applications of H2O2 are known in the removal of pollutants from wastewater, such as sulphites, hypochlorites, nitrites, organic compounds and chlo-rine.

For example, ozonation is expected to be a strong oxidant on all sludge components: whether cellular biomass or inert compounds. This treatment on cellular biomass induces cell lysis-cryptic growth, while its effect on inert solids is an enhancement of solubilisation with a potential increase of biodegradability of the compounds released.
