Ultraviolet Light Disinfection
UV is part of the electromagnetic spectrum, which includes visible light. Concentrated sunlight contains UV, which is a powerful natural disinfectant. UV equipment is now available for the treatment of swimming pool water. UV allows safe reduction in microbial contamination and chloramine levels to meet health guidelines.
The primary purpose of UV is to initiate photochemical and photooxidation reactions which destroy chloramines, a range of compounds responsible for unpleasant smells in pools. This is particularly important where features such as water slides and waves give a greater surface area for the release of chloramines into the air. UV reduces the chloramines burden, making the atmosphere safer and more pleasant. UV has an important secondary action: it kills bacteria, viruses and mold spores, thus reducing the risk of transmission of stomach, skin and respiratory tract infections to bathers.
