Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant
organic constituents from industrial and municipal wastewater. The aim of this study was
to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light
process and Fenton’s reactions in wastewater treatment. The main reactions and the
operating parameters (initial concentration of the target compounds, amount of oxidation
agents and catalysts, nature of the wastewater etc) affecting these processes are
reported, while several recent applications to wastewater treatment are presented. The
advantages and drawbacks of these methods are highlighted, while some of the future
challenges (decrease of operational cost, adoption of strategies for processes integration)
are discussed.
