Ozone has been an effective biocide for over 100 years, reduces or eliminates biomass, Legionnaires' Disease, bacterial delignification and corrosion, oxidizes many organic and inorganic contaminants. By automatically maintaining the ozone concentration in the water through Redox control, the pH level is maintained while biological fouling/scale deposition are greatly reduced or eliminated. Previous ozone installations have not used supplemental treatment chemicals. This allows the cooling water to be recycled without fear of high concentrations of dissolved solids associated with corrosion and without containing potential environmental hazards while eliminating continuous blowdown. Operating and maintenance costs are materially reduced and efficiency increased.
