How does calcium carbonate coating help in water systems?

• A. It adds minerals to the water
• B. It helps to dissolve impurities
• C. It forms a protective layer against corrosion
• D. It enhances chemical treatment methods

Answer: (C)

Calcium carbonate coating is beneficial in water systems primarily because it forms a protective layer against corrosion. When calcium carbonate precipitates onto surfaces, it creates a barrier that minimizes direct contact between the substrate (such as metal piping) and corrosive agents in the water. This protective layer can prevent deterioration of the infrastructure by mitigating the effects of corrosive substances, such as oxygen and carbon dioxide, which can lead to rust and structural failure over time. By establishing this barrier, the longevity and reliability of the water system can be significantly improved, reducing maintenance costs and the risk of leaks or failures. In contrast, while calcium carbonate does add minerals to the water, this option does not address the protective aspect crucial for corrosion prevention. Similarly, although calcium carbonate can participate in various chemical processes, its primary role in providing a protective anticorrosive layer is the most critical function within water treatment systems.
