Ozone was found effective biocide after evaluation of more than two years of ozone application for treatment of mechanical draft counterflow water cooling towers at large gas production utility site, and for treatment of cooling towers of cooling/heating systems of large building complexes.

Ozone was not found to be a corrosion inhibitor nor descaling agent. The pH and alkalinity were the favorable conditions for corrosion protection of materials at higher cycles of concentrations. Also, at higher cycles of concentrations, the chemistry of clean recirculating cooling tower water forms a microscopic, dense and barrier functioning protective film on metal surfaces.
