What is a common method used to inactivate pathogens in pools, aside from chlorine?

Ultraviolet (UV) light systems are recognized as an effective alternative method for inactivating pathogens in swimming pools. This technology works by exposing water to UV light, which disrupts the DNA of microorganisms, rendering them unable to reproduce and thus effectively neutralizing them. UV systems are particularly beneficial because they can significantly reduce the needed levels of traditional disinfectants such as chlorine, which can lead to a more comfortable swimming experience for users while also maintaining adequate sanitation.

In contrast, ozone generators can also inactivate pathogens, but their effectiveness is often dependent on the ozone concentrations and contact time with the water. Hydrogen peroxide has disinfectant properties, but it is not commonly used in pool sanitation due to factors like stability and the need for specific concentrations. Saltwater systems, while they generate chlorine through electrolysis, do not independently inactivate pathogens without chlorine's active presence. Therefore, UV light stands out as a direct method for pathogens inactivation that enhances overall water quality management.
