What is cooling tower treatment?


Cooling tower treatment is an essential part of the preventative maintenance program for cooling towers and cooling water systems for industrial applications.


Cooling towers are a cost-effective and energy efficient way of rejecting the heat generated by numerous industrial applications, such as:

  • HVAC systems
  • Manufacturing processes
  • Power generation plants
  • Chemical plants
  • Oil refineries

Why is the treatment of cooling towers so important?

The treatment of cooling towers is a vital operation for many industries around the world in order to prevent problems that lead to inefficient water cooling and costly fixes. The most common issues from untreated cooling towers include:

Corrosion – the mix of moisture and heat in cooling towers and cooling systems make them a prime target for corrosion to occur.

Scaling – inorganic materials such as calcium carbonate, calcium phosphate and silica forms on the surface of cooling towers causing an excess of scale.

Fouling – a build-up of solid material accumulates in untreated cooling towers which can cause a deterioration of plant equipment and reduce the life of cooling systems.

Microbial contamination – heat and moisture encourage the growth of microorganisms, causing the accumulation of slime which, in turn, reduces the efficiency of the heat transfer.
