94-07: Design Consideration for Ozone Water Treatment Systems in Cooling Towers Cooling Tower ConversionAbstract: The design of ozone systems for cooling tower water treatment has been varied. This paper discusses the various designs and presents both the positive and negative sides to the design options. Those design options that have led to system failure are also presented. The most important design factors are the ozone generating equipment sizing, dissolving ozone in water and the distribution of the ozone containing water into the cooling tower

Ammonia in the cooling loop poses an additional challenge for Hypochlorite or oxidizing biocides in controlling the microbiological activity since monochloramines are not effective biocides

In a context of climate change

All of the biocides proved to be highly effective against L
