Ozone attracts widespread attention as an important oxidising agent in a wide range of industrial applications. As a consequence of its attractive properties, many methods of enhancing the production rate of ozone have been investigated. This book explained about an investigation into an APGD and PSD techniques of ozone generation. Chapter 1 and 2 of the book provides an ozone brief history and basic understanding of the gas discharge. A review of physical configuration and the electrical parameters is presented in Chapter 3. In Chapter 4, a study is made of the stability of the APGD. A comparative study between APGD and PSD is presented in Chapter 5. Chapter 6 presents the effect of a cross magnetic field on an AC corona and the PSD techniques. Chapter 7 describes the use of dimensional analysis in investigating the effect of the electrical and the discharge configuration parameters of a PSD. The analysis and results presented in this book should help in designing a small and large size of ozone generator and should be especially useful to the technical in ozone industries or anyone else who may considering designing their own ozone generator.
