Chemistry of Ozone in Water and Wastewater Treatment

Even though ozone has been used for a long time for disinfection and oxidation in water treatment, there is a lack of critical information on the transformation of organic compounds. This has become more important in recent years because there is considerable concern about the formation of potentially harmful degradation and oxidation products from reactions with matrix components. In recent years, a wealth of information on the products formed has accumulated, and substantial progress has been made in understanding the mechanistic details of ozone reactions in aqueous solutions. Based on the latter, this may allow us to predict the products of as-yet-unstudied systems and assist in evaluating toxic potential when certain classes are known to show such effects. Keeping this in mind, Chemistry of Ozone in Water and Wastewater Treatment: From Basic Principles to Applications discusses mechanistic details of ozone reactions as far as they are known to date and applies them to the large body of studies on micropollutant degradation (such as pharmaceuticals and endocrine disruptors) already available. Extensively quoting the literature and updating the available compilation of ozone rate constants gives the reader a text at hand on which his research can be based. Moreover, those responsible for planning or operating ozonation steps in drinking water and wastewater treatment plants will find salient information in a compact form that is otherwise quite dispersed. A critical compilation of rate constants for the various classes of compounds is given in each chapter, including all the recent publications. This is a very useful source of information for researchers and practitioners who need kinetic information on emerging contaminants. Furthermore, each chapter contains a large selection of examples of reaction mechanisms for the transformation of micropollutants such as pharmaceuticals, pesticides, fuel additives, solvents, taste and odor compounds, and cyanotoxins.
