This paper brings together the requirements and experiencs of the supplier of ozone generating equipment and the user of this equipment. The technical requirements of the ozone generator on the feed gas, the main characteristics of the systrem alternatives, the on-site experience and the development of criteria for future applications are described. The particular application of ozone and the quantities required are detailed to provide a full understanding of the background and environment of the case study and its demands on the system selection. The evolution from an air fed system to an oxygen fed system is outined.
