Microbial growth in cooling towers can lead to what type of operational issue?

Microbial growth in cooling towers can significantly hinder their operational efficiency. When microbial populations proliferate, they can create biofilms and slime, which accumulate on the heat exchange surfaces. This buildup acts as insulation, decreasing heat transfer and ultimately causing the cooling system to work harder to achieve the desired cooling effect.

As a result, reduced efficiency translates to increased energy consumption, higher operational costs, and potential overheating of system components, which can lead to further mechanical issues. It is essential to manage microbial growth effectively through regular cleaning and chemical treatment to maintain optimal system performance.
