Criteria for the selection of the feed gas for ozone generation

摘要

This paper b rings together the requireements and experiences of the supplier of ozone generating equipment and the user of this equipment. The technical rquirments of the ozone generator on the feed gas, the main characteristics of the system 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 evolutionfrom an air fed system to an oxygen fed system is outlined. This Paper describes the joint evaluation of the choice of feed gas for Purton by Bristol Water Plc and Ozonia using the experience gained at the Littleton Works and the technical assessment during the pre-contract stage of the Purton Treatment Works Development Scheme.
