The chlorine room must be kept above what temperature to avoid the formation of Chlorine Hydrate, also known as "Green Ice"?

The correct temperature to keep the chlorine room above to prevent the formation of Chlorine Hydrate, commonly referred to as "Green Ice," is indeed 60°F. Chlorine hydrate forms when chlorine gas comes into contact with water at lower temperatures, resulting in a solid that can cause operational issues in water treatment facilities. Maintaining a temperature above 60°F helps ensure that chlorine remains in its gaseous state, allowing for safe and efficient chlorine handling and storage. This practice is crucial for preventing safety hazards and maintaining effective chlorination processes in water treatment operations.
