UV disinfection of domestic pools and spas is a chemical-free method of killing bacteria by shortwave ultraviolet light. To ensure a safe and pleasant pool environment without using strong disinfection chemicals, ultraviolet water purification destroys organic pollutants instantly as the water passes through the treatment chamber. The ultraviolet sterilization system we provide for private pools is particularly suitable for users who are sensitive to the usual swimming pool disinfectants, heavy metals from ionic purifiers or allergic to chlorine.
