Dissolved gases, particularly oxygen and carbon dioxide, can also pose significant risks in boiler systems. Oxygen facilitates corrosion, while carbon dioxide can combine with water to form carbonic acid, lowering pH and increasing corrosive potential. Deaerators are utilized to remove these gases from the feedwater, but often, chemical oxygen scavengers such as hydrazine or sulfites are included in the treatment regimen. These compounds effectively neutralize dissolved oxygen, protecting the boiler from corrosion.
These physical methods serve as a foundation for water treatment systems, effectively reducing the turbidity and suspended solids in water, making subsequent chemical treatments more efficient.

Corrosion is another major issue in chilled water systems that can lead to equipment damage and unscheduled downtime. The presence of dissolved oxygen, carbon dioxide, and chlorides can exacerbate corrosion processes. To mitigate this risk, corrosion inhibitors, such as nitrites, phosphates, or azoles, are added to the chilled water. These inhibitors form a protective film on the metal surfaces, effectively shielding them from corrosive agents. Implementing a tailored chemical treatment program not only prevents corrosion but can also extend the lifespan of the system components.
