Advanced oxidation processes work by generating reactive radicals that can effectively breakdown pollutants. This is achieved through various methods such as ultraviolet (UV) radiation, ozone (O3), hydrogen peroxide (H2O2), and photocatalysis. These methods can be used individually or in combination to enhance the efficacy of pollutant degradation. For example, the combination of UV light and hydrogen peroxide is common in water treatment facilities because it can effectively produce hydroxyl radicals.
