Cooling towers are very common in industrial complexes and commercial buildings. The one thing common is that they use a lot of water. Water conservation requires that water to be recirculated. And that recirculated water needs to be treated to ensure that it does not corrode or scale the cooling elements. Additionally there are possibilities of organic growth within the water which requires treatment with biocides.
Corrosion Inhibitors – These are injected in the recirculated water to prevent corrosive damage to the components.
