Oxidation and photochemical water treatment processes: abatement of organic contaminants, disinfection, and by-product formation
By Associate Prof. Yunho Lee, Associate Professor in School of Earth Sciences and Environmental Engineering at Gwangju Institute of Science and Technology (GIST), Korea
Abstract:
Ozonation (O3 and O3/H2O2) and UV-based processes (UV and UV/H2O2) are widely applied in drinking water treatment for the purpose of disinfection and oxidation of micropollutants. These (photochemical) oxidation processes have also received increasing attention as a potential option for enhanced wastewater treatment to eliminate various micropollutants and recently to inactivate antibiotic-resistant bacteria and genes. In this seminar, recent advances in applications of ozonation and UV-based processes for drinking water and wastewater treatment are presented including application history and status in Korea.

Speaker’s bio:
Professor Yunho Lee is an associate professor in School of Earth Sciences and Environmental Engineering at Gwangju Institute of Science and Technology (GIST), Korea. He received a Ph.D. in Chemical Engineering Department at Seoul National University, Korea in 2005 and did a postdoctoral research at Swiss Federal Institute of Aquatic Science and Technology (Eawag) before joining GIST in 2011. His research focuses on characterizing and optimizing oxidative water treatment processes for drinking water and municipal and aquaculture wastewater for abating organic and biological contaminants of concern with minimized toxic by-product formation. He uses principle-based approaches for his researches such as chemical kinetics and mechanisms, which are also combined with analytical, toxicological, microbiological, and process engineering aspects. He has authored more than 50 papers in water science and engineering. He has been an editor of Journal of Environmental Chemical Engineering (Elsevier) since 2013 and an editorial board member of Environmental Science: Water Research and Technology (RSC), 2014-2017.
