  • Can ozone be used in water treatment?
  • The efficacy of ozone as an oxidant and disinfectant triggered its introduction into water treatment since more than a century. Recently ozonation has sparked interest in other applications including advanced wastewater treatment where ozone is applied for the abatement of micropollutants and in potable water reuse.
  • Why is ozonation important in wastewater treatment?
  • Recently ozonation has sparked interest in other applications including advanced wastewater treatment where ozone is applied for the abatement of micropollutants and in potable water reuse. As with other oxidants, the formation of disinfection byproducts during ozonation is inevitable.
  • When should ozone be applied in water treatment?
  • Ozone can be applied at an early stage in water treatment (pre-ozonation) when the aim is to eliminate taste and odour compounds, oxidize inorganic pollutants (e.g., iron and manganese), enhance coagulation, or eliminate DBP precursors .
  • Which compounds are not oxidized by ozone during water treatment?
  • Considering the competition of substrates for ozone in a given water matrix, substrates which react very slowly typically do not undergo direct oxidation by ozone in real water treatment conditions. MTBE is an example of compounds which are not directly oxidized by ozone during water treatment but rather by hydroxyl radicals .
