To enhance the performance of ozonation, photocatalysts, UV or visible radiation, and H₂O₂ can be integrated in advanced oxidation processes. On its own, UV radiation can photodegrade some pharmaceuticals, but will not effectively remove all xenobiotics. Under UV irradiation, H₂O₂ generates HO• radicals, which are broad-spectrum oxidants capable of photodegrading pharmaceuticals (Sharma et al., 2019). These advanced oxidation processes successfully remove a range of pharmaceuticals including refractory organics (Patel et al., 2019). In addition, H₂O₂ can be applied in enhancing ozonation through perozonation, via mechanisms similar to O₃/UV, augmented with H₂O₂.
