What could be a consequence of an initial treatment of film-forming chemicals in a cooling tower being too weak?

When the initial treatment of film-forming chemicals in a cooling tower is too weak, one of the primary consequences is the potential for severe corrosion in unprotected areas. Film-forming chemicals are designed to create a protective barrier on metal surfaces within the cooling system, thereby inhibiting corrosion caused by the water and the environmental factors present. If this treatment is insufficient, the protective film may not form adequately or may wear off, leaving the underlying metal surfaces exposed to corrosive elements.

As a result, unprotected areas become vulnerable to deterioration, which can compromise the structural integrity of the cooling tower and associated components. This significantly increases the risk of leaks and equipment failure. Additionally, the presence of corrosion can lead to the production of rust and other byproducts that further contaminate the water system and can cause blockages.

Although increased energy consumption, reduced water flow, and increased maintenance costs can also arise from inadequately treated systems, the most immediate and significant risk from a weak initial treatment is certainly the potential for severe corrosion, which can lead to extensive damage and costly repairs. This highlights the importance of properly dosing film-forming chemicals to ensure effective protection against corrosion in cooling towers.
