Cooling Tower

Ozone is used as a biocide in cooling tower applications. Ozone can lower costs and offers a green alternative to traditional chemicals. Benefits to ozone use in cooling towers are:

  • Lower chemical costsozone for cooling tower
  • Lower overall operational costs
  • Lowers discharge chemicals
  • Prevents condenser fouling
  • Green, environmentally friendly chemical alternative
  • Lower energy costs



 Ozone is used in place of existing chemicals as a biocide.  Lower chemical consumption and therefore lower chemical discharge is the result when ozone is implemented.  Cost savings can be realized by reducing chemical consumption and lower costs for discharge water treatment or costs.  


Depending upon cooling tower operation and conditions water consumption can be reduced, energy costs can be lowered and the overall efficiency of the cooling tower can be improved.
