Abstract:
Nowadays, increased human activity, industrialization, and urbanization result in the production of enormous quantities of
wastewater. Generally, physicochemical and biological methods are employed to treat industrial e uent and wastewater and have
demonstrated high e cacy in removing pollutants. However, some industrial e uent and wastewater contain contaminants that
are extremely di cult to remove using standard physicochemical and biological processes. Previously, electrochemical and hybrid
advanced oxidation processes (AOP) were considered a viable and promising alternative for achieving an adequate e uent
treatment strategy in such instances. ese processes rely on the production of hydroxyl radicals, which are highly reactive
oxidants that e ciently break down contaminants found in wastewater and industrial e uent. is review focuses on the removal
of contaminants from industrial e uents and wastewater through the integration of electrochemical and advanced oxidation
techniques. ese processes include electrooxidation, electrocoagulation/electro occulation, electro otation, photo-Fenton,
ozone-photo-Fenton, sono-photo-Fenton, photo-electro-Fenton, ozone/electrocoagulation, sono-electrocoagulation, and peroxi/
photo/electrocoagulation. e data acquired from over 150 published articles, most of which were laboratory experiments,
demonstrated that the hybrid process is more e ective in removing contaminants from industrial e uent and wastewater than
standalone processes.
