One of several combination oxidation processes. Advanced chemical oxidation processes use (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components. The processes can completely oxidise organic materials to carbon dioxide and water, although it is often not necessary to operate the processes to this level of treatment.
A wide variety of advanced oxidation processes are available:
- Chemical oxidation process using hydrogen peroxide, ozone, combined ozone & peroxide, hypochlorite, Fenton's reagent, etc.
- Ultra-violet (UV) enhanced oxidation such as UV/ ozone, UV/ hydrogen , UV/air
- Wet air oxidation and catalytic wet air oxidation (where air is used as the oxidant)
