Why does rapid pH adjustment in water treatment pose a risk?

Rapid pH adjustment in water treatment can lead to increased corrosion in a boiler due to the abrupt changes in chemical conditions, which can destabilize the protective oxide layer on metal surfaces. When pH levels fluctuate quickly, it can create an environment conducive to corrosion by altering the solubility of various compounds, particularly iron and steel, which are common materials used in boiler construction.

In addition, rapid pH changes can lead to the formation of harmful acids or the disruption of an established balance in the water chemistry, further accelerating the corrosion process. Over time, this can lead to severe damage to boiler components, resulting in costly repairs and potential safety hazards. Therefore, maintaining a stable pH level is crucial for ensuring the longevity and safe operation of boiler systems.
