Reaction Rates and Mechanisms of Advanced Oxidation Processes (AOPs) for Water Reuse

Principal Investigator
William J. Cooper,  University of California, Irvine, CA

The field of water reuse has seen great strides with multiple benefits in the application of new techniques and technologies, and these will continue to evolve as additional processes are found and new contamination problems are identified that require nontraditional solutions.  In particular, contaminant destruction technologies such as advanced oxidation and/or reduction processes (AO/RPs) will be recommended and implemented in many new plants and likely will be specified in upgrading existing plants.

The main objective of this study was to develop a better understanding of the water-based free radical chemistry in the destruction of organic microconstituents by:

  • Determining reaction rates of 30 to 50 target chemicals with hydroxyl radicals, ·OH, and hydrated electrons, e-aq.
  • Elucidating destruction mechanisms for five selected target compounds representative of broader classes of organic microconstituents.
  • Determining the efficiency of the hydroxyl radical-mediated destruction of bisphenol A and three other model organic contaminants, in pure water, laboratory solutions containing bicarbonate ion and/or dissolved organic matter, and treated wastewaters of different quality.

The long-term goal of research of this nature is to provide the data necessary to develop kinetic models that describe the underlying chemistry for advanced oxidation process applications.
