Which disinfectant is commonly used for pool water sanitation?

Chlorine is a widely recognized and commonly used disinfectant for pool water sanitation due to its effectiveness in killing bacteria, viruses, and other pathogens present in the water. Chlorine works by releasing hypochlorous acid when it dissolves in water, which is a powerful oxidizing agent that disrupts the cellular processes of microorganisms, leading to their elimination.

This disinfectant is favored for its cost-effectiveness, ease of use, and immediate availability. It is also effective in maintaining a residual level in the pool, ensuring ongoing sanitation between regular chemical treatments. Chlorine can be administered in various forms, including tablets, granules, and liquid, providing flexibility in its application based on the specific needs of the pool.

Other disinfectants, while effective in certain contexts, may not have the same widespread usage or practicality for residential and commercial pool sanitation as chlorine does.
