What is a major method to treat corrosion due to free oxygen?

Corrosion caused by free oxygen in water systems can lead to significant damage and degradation of pipes and equipment. A major method to treat this issue is by deploying oxygen scavengers. These are chemical agents that react with dissolved oxygen in water, effectively reducing its concentration and preventing it from promoting corrosion.

When oxygen is present in water, it can facilitate electrochemical reactions that corrode metal surfaces. Oxygen scavengers work by chemically binding to or reacting with oxygen, thus neutralizing its harmful effects. Common examples of oxygen scavengers include ascorbic acid, sodium bisulfite, and other reducing agents that convert free oxygen into benign compounds.

By using oxygen scavengers, the risk of corrosion is significantly mitigated, extending the lifespan of water systems and improving their overall reliability. This approach is particularly effective in closed loop systems where the control of oxygen levels is crucial for maintaining system integrity.
