A Review of Ozone Generating Facilities in Some U.S. Water and Wastewater Treatment Plants

In previous years, the start-up and operation of ozone systems at U.S. municipal water and wastewater treatment facilities has resulted in numerous problems. Some of these problems were of such a magnitude that the operating agency decided to abandon the ozone system. In other cases, the system is operating and the problems are resolved. An investigation of 11 U.S. facilities was conducted to determine what problems were experienced and how the problems were resolved.
