Wastewater Treatment by Physical, Chemical, Photochemical, and Biological Processes, and Their Combinations

Dear Colleagues,

Due to the limitations of individual physical, chemical, photochemical, or biological processes in their effectiveness or economic feasibility, most processes are not cost-effective or efficient on their own to treat wastewaters, such as high-strength wastewaters. Advanced oxidation processes (AOPs) are alternatives to treat wastewaters containing non-biodegradable, toxic, inhibitory, and recalcitrant organic contaminants. Although the main advantages of AOPs are their destructive and non-selective nature, as well as their high rates of reactions in comparison to biological processes, they may not be cost-effective on their own. An alternative treatment is the biodegradability enhancement of wastewater by a photochemical pre-treatment or post-treatment using AOPs. Therefore, the focus of this topic is on the latest developments in all AOPs, including photochemical reaction engineering, photoreactor design and kinetics, photocatalyst development, biological processes for wastewater treatment including high-strength actual wastewaters, biokinetics, technical improvements for municipal wastewater treatment plants including process control, and/or combinations of different physical, chemical, photochemical, and biological processes to maximize organic degradation in wastewater while being cost-effective.
