Water Treatment Insights
Technical articles, tools and training from PWR and Nalco Water to help engineering teams protect their systems and improve efficiency.
Cooling Tower Water Calculator
Estimate evaporation, blowdown and make-up water, and what you could save by running at higher cycles of concentration.
Your Tower
Estimated Result
| Current | Target | |
|---|---|---|
| Make-up water / year | – | – |
| Blowdown / year | – | – |
Evaporation: –
Estimate only. Evaporation ≈ 0.00153 × recirculation × ΔT; drift and other losses ignored. The cycles a tower can safely run depend on make-up water chemistry and the treatment program. Ask us to assess yours.
