What is the main byproduct of chlorination in pools?

Chloramines are indeed the main byproduct of chlorination in pools. When chlorine is added to pool water, it reacts with organic material such as sweat, urine, and bacteria. This reaction leads to the formation of chloramines, which are responsible for the characteristic smell often associated with chlorinated pools, as well as irritation to the eyes and skin of swimmers.

Chloramines are less effective as disinfectants compared to free chlorine, making it essential for pool operators to manage chloramine levels to ensure water quality and swimmer comfort. Regular maintenance, such as performing shock treatments with higher doses of chlorine, helps to break down chloramines, preventing their buildup and mitigating any negative effects they may have. Understanding the formation of chloramines is crucial for maintaining safe and enjoyable swimming conditions.
