| Abstract |
Oxidation processes such as chlorination, ozonation, and advanced (photochemical)oxidation processes (UV and radical based processes) are widely applied in drinking water treatment for the purpose of disinfection and oxidation of micropollutants. Oxidation processes have also received increasing attention as a promising technology for enhanced wastewater treatment to eliminate various micropollutants and more recently to inactivate antibiotic resistant bacteria and genes. The efficiency of oxidation process for treating target contaminants (micropollutants, pathogens, or resistant genes) depends on (1) the reactivity of an oxidant with a target contaminant, (2) the dosage of an oxidant and the stability of an oxidant in a given water matrix, (3) the removal of undesirable effects of a target contaminant. In this seminar, recent advances in applications of oxidation technologies for eliminating organic contaminants during water treatment are presented with a focus on identifying transformation products and pathways, and assessment of biological activity (e.g., toxicity) changes. Needs for more active use of principle-based approaches (e.g., reaction pathway model, quantitative toxicological model, biodegradability model) and advanced analytical tools (e.g., high-resolution mass spectrometry, bioanalytical methods, in silico prediction methods) for determining the overall process efficiency will be discussed. |
