What does super chlorination achieve in a swimming pool?

Super chlorination is a process that involves adding a higher dose of chlorine to a swimming pool to achieve a concentration of free available chlorine in the range of 5 to 10 parts per million (ppm). This elevated chlorine level is particularly effective for breaking down chloramines and other organic contaminants that accumulate in pool water, especially after heavy use or following a significant rain event.

By reaching these elevated levels of chlorine, super chlorination effectively sanitizes the water, eliminates bacteria and algae, and improves overall water quality. This method is often used after peak usage times or after a pool has been closed for maintenance to ensure that the water remains safe and clean for swimmers.

While maintaining water balance, setting water temperature, and reducing swimmer discomfort are important aspects of pool maintenance, the specific objective of super chlorination is to achieve that higher concentration of free chlorine, thereby enhancing disinfecting efficacy and ultimately contributing to better water clarity and hygiene.
