95-12: Guidelines and Examples of Ozone in Cooling Tower Applications

This paper discusses the current state of the art in applying ozone as a solo treatment and with supplementary cooling tower treatments. These supplementary treatments include chemical treatments as well as additional electromechanical equipment. Different water chemistries will be reviewed in light of the success and failure of the ozone systems. Ozone as a biocide and legionella control will also be reviewed. Cooling tower sytems using ozone with and without other treatment will be used as example.
