Photo-assisted electrochemical advanced oxidation processes for the disinfection of aqueous solutions: A review.

ABSTRACT: Disinfection is usually the final step in water treatment and its effectiveness is of paramount importance in ensuring public health. Chlorination, ultraviolet (UV) irradiation and ozone (O₃) are currently the most common methods for water disinfection; however, the generation of toxic by-products and the non-remnant effect of UV and O₃ still constitute major drawbacks. Photo-assisted electrochemical advanced oxidation processes (EAOPs) on the other hand, appear as a potentially effective option for water disinfection. In these processes, the synergism between electrochemically produced active species and photo-generated radicals, improve their performance when compared with the corresponding separate processes and with other physical or chemical approaches.
