Ozone Use in Cooling Tower Water Treatment

The use of ozone in cooling tower treatment has received a vast amount of attention in recent years for the benefits it offers the industry.

Ozone Benefits for Cooling Towers

  • Safe and easy to use
  • Ozone decomposes organic waste
  • Very effective in removing biofilms
  • Environmentally friendly treatment
  • Ozone is effective in a wide pH range
  • Ozone requires no additional disinfectants
  • Ozone is 3,000x more germicidal than chlorine
  • Reduced permit costs for treated water discharge
  • Very effective against due to good biofilm removal capacities
  • Destroys all types of microorganisms instantly, including Legionella
  • Low corrosion rates in the system, including copper heat exchangers, because there are no chlorinated compounds
  • Disinfectant with a high-efficiency level (an ozone concentration of 0.1 to 0.2t ppm is, in most cases, very effective in keeping the cooling tower and the cooling circuit clean)
  • Ozone does not leave any chemical residues. Ozone’s only byproduct is oxygen.

Operational Savings

  • Reduced maintenance
  • Reduced consumables
  • Reduced water consumption
  • Reduced anti-scaling and anti-corrosion agents
  • Reduced energy consumption due to increased efficiency
  • Remove the need for chemical shipping, storage, and handling
