Electrochemical Advanced Oxidation Processes (EAOPs) for Disinfecting Water—Fresh Perspectives

Abstract

During recent decades, study endeavors have been performed at elaborating more efficient techniques for handling waters carrying pathogens. Among such methods, the famous electrochemical advanced oxidation processes (EAOPs) have induced augmenting attention. Such methods are founded on electro-chemically producing powerful oxidants like hydroxyl radicals (●OH). This work portrays a global view on killing different microorganisms by some usual EAOPs. Electrochemically-driven techniques are earning importance thanks to encouraging findings noted in the literature. A shortage of comprehension in the pathways of electrode scaling and fouling has happened partially, because the most investigation is realized in batch reactors rather than continuous flow reactors where solutes and pathogens that noxiously influence setup efficiency pass by electrode surfaces. The coming study has to deal with the treatment of more realistic water matrices (i.e., composition and concentration). This will help to identify fit-for-purpose and niche opportunities for electrochemical-ly-driven technologies.
