Ultraviolet Light (UV) Disinfection

Ultraviolet Light (UV) Disinfection

Ultraviolet light is used to disinfect water in some water treatment plants. Exposure to adequate doses of UV light renders bacteria, viruses and protozoa non-pathogenic to humans. In the UV disinfection process, the water passes through reactors with sufficient UV lamps to deliver the required UV dose. The required UV dose is dependent on certain water quality factors such as clarity, dissolved compounds and microorganisms present. A listing of the water treatment plants that employ UV disinfection can be found here .
