AquFlow Pumps Advantage in Cooling Tower Applications

Corrosion Inhibitors – These are injected in the recirculated water to prevent corrosive damage to the components.
Scale Inhibitors – Scaling can be more damaging than corrosion sometimes as it drastically reduces the heat transfer. Anti-scalants are injected to prevent scaling in the pipes and tubes.
Biocides – There are two options here Non-Oxidizing Biocides and Oxidizing Biocides. The Non-Oxidizing biocides are dosed once or twice a week and they typically require and contact time of 4 hours. Oxidizing Biocides such as Chlorine and Bromine are used depending upon the pH of the water.

Bromine is effective for pH up to 9 and Chlorine is good for lower pH around 6 or 7. Their level are usually measured using Redox (Oxidation Reduction Potential – ORP).
