What is the role of ultraviolet (UV) disinfection in pools?

The role of ultraviolet (UV) disinfection in pools primarily involves reducing pathogens in water through exposure to UV light. This process works by irradiating water as it passes through a UV chamber, which destroys or inactivates harmful microorganisms such as bacteria, viruses, and protozoa. The effectiveness of UV disinfection is based on the principle that the UV light disrupts the DNA or RNA of these pathogens, rendering them unable to replicate and cause infection.

While UV disinfection can contribute to overall water quality and safety, it is not a standalone method for maintaining proper pool chemistry or balance. For example, while it can assist in minimizing the reliance on traditional chemical disinfectants, its primary function is pathogen control rather than directly managing chemical levels or enhancing water clarity. Furthermore, maintaining proper pH levels is crucial for swimming pool health but is achieved through other chemical treatments rather than UV disinfection.
