Treatment of Contaminants of Emerging Concern in Water Using Homogeneous and Heterogeneous Advanced Oxidation Processes

Abstract

Advanced oxidation processes are becoming important processes in advanced water treatment trains for the treatment and purification of water and wastewater. Applications include treatment of surface water, groundwater, municipal water, and industrial water. More recently, applications extended to water reuse for various purposes (i.e., direct and indirect potable reuse).  Professor Dionysiou will present examples of his work on the treatment of contaminants of emerging concern for application related to drinking water treatment and water reuse applications. He will present details on the mechanism of degradation of cyanotoxins, pharmaceuticals, pesticides, sunscreen ingredients and other contaminants of concern using heterogeneous (i.e., semiconductor photocatalysis, photo-Fenton-like, dark-based catalytic) and homogeneous (UV/H2O2, UV/persulfate, UV/chlorine)  advanced oxidation processes. Examples will be provided on the synthesis of novel photocatalytic materials as well as the mechanism of degradation by reactive oxygen species.  Aspects of modeling and structure-activity relationships will be presented. The role of water quality parameters and process integration will be discussed. 

Bio

Prof. Dionysiou (Dion) is currently a Professor of Environmental Engineering and Science Program at the University of Cincinnati. He teaches courses and performs research in the areas of drinking water quality and treatment, advanced unit operations for water treatment, advanced oxidation technologies and nanotechnologies, and physical-chemical processes for water quality control. He has received funding from NSF, US EPA, NASA, NOAA/CICEET, USGS, USDA, Ohio Sea Grant, USAID, and DuPont. He is currently one of the editors of Chemical Engineering Journal, Editor-in-Chief of the Journal of Advanced Oxidation Technologies, and Editor-in-Chief of the Journal of Environmental Engineering (ASCE). He is a member of the Editorial Boards of several other journals. Dr. Dionysiou is the author or co-author of over 370 refereed journal publications, over 86 conference proceedings, 32 book chapter publications, 28 editorials, and more than 600 presentations. He has edited/co-edited 6 books on water quality, water reuse, ferrates, and photocatalysis. He is currently co-editing a book on harmful algal blooms. Dr. Dionysiou’s work received over 25,000 citations with an H factor of 84 (Google Scholar).
