Ozone Reaction Kinetics for Water and Wastewater Systems
Fernando J. Beltrán (2004). CRC Press LLC, 2000 N.W. Corporate Blvd., Boca Raton, FL 33431, 384 pp., $149.95, hardcover, ISBN 1-56670-629-7.

This is an excellent book for anyone who wants to start working with ozone applications for water and wastewater treatment, or already is. 

The first two chapters, devoted to general information about the ozone molecule and the reactions of ozone in water, describe the most important ozone decomposition mechanisms. 

The author then discusses kinetics of the direct ozone reactions, taking into account biochemical oxygen demand and chemical oxygen demand. An interesting addition is the table including recent literature on wastewater ozonation, in which wastewater type and reaction features are described. These types of tables, found throughout the book, are a very useful way to obtain more specific information about the applications of ozone.

The fundamentals of gas–liquid reactions, while not really necessary in this book, are a good reminder of the different theories. 

The next part of the book covers indirect ozone reactions, and therefore the advanced oxidation processes. These processes, which appear to be a new trend, are promising technologies for treating a whole range of pollutants. Different advanced oxidation processes are described: ozone–hydrogen peroxide, ozone, ultraviolet radiation, and finally heterogeneous catalytic ozonation. These chapters contain a wealth of information on the kinetics of these processes as well as many useful resources. Kinetic modelling of ozone processes also is covered.

This book gives water quality professionals a useful reference for fundamental chemistry, and mechanisms and kinetics of direct and indirect reactions of ozone, as they specifically apply to wastewater.
