Ozone for Cooling Tower Water Treatment
The use of ozone in cooling tower treatment has received a great deal of attention in recent years. In the prevention and control
of legionnaires disease (legionella) causing microbes, ozone has taken an eminent roll. The specific characteristics of the
disinfectant make sure ozone gets the job done where others fail
There are additional specific characteristics that give ozone a great deal of appeal to cooling tower users.
Case Details
Advantages of Ozone Application in Cooling Tower Water
- Safe and easy in use
- Low maintenance costs
- Ozone is produced on-site and requires no storage of dangerous chemicals
- Ozone requires no additional disinfectants
- No cocktail of disinfectants necessary. Micro-organism can not get resistant to ozone after prolonged use of ozone.
- High efficiency as disinfectant. A residual 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.
- Very effective in removing biofilms
- Higher efficiency of heat exchangers due to reduced biofilm formation.
- Due to good biofilm removal capacities very effective against Legionella.
- No chlorinated compounds. Very low corrosion rates in the system.
- No persistent chemicals or disinfectants in bleed. Ozone breaks down to oxygen.
- In some cases ozone can replace disinfectants and also dispergents and inhibitors.
- In many cases a higher concentration factor is possible.
- Lower operational costs and in many cases a lower overall costs.
- Ozone is effective in a wide pH range.
- Also effective for mussel growth.
