Recent Progress in TiO2-Mediated Solar Photocatalysis for Industrial Wastewater Treatment

The current paper reviews the application of TiO 2 -mediated solar photocatalysis for industrial wastewater treatment, starting with a brief introduction on the background of industrial wastewater and the development of wastewater treatment processes, especially advanced oxidation processes (AOPs). We, then, discuss the application of solar TiO 2 photocatalysis in treating different kinds of industrial wastewater, such as paper mill wastewater, textile wastewater, and olive mill wastewater. In the end, we compare solar TiO 2 photocatalysis with other AOPs in terms of effectiveness, energy, and chemical consumption. Personal perspectives are also given, which may provide new insights to the future development of TiO 2 photocatalysis for industrial wastewater.
