Ultraviolet (UV) light has been used to disinfect water supplies for more than 75 years, but only recently have home UV systems become available. Municipalities sometimes use UV instead of chlorination for disinfection to avoid the byproducts that chlorination may produce in the treated water supply. The primary advantage to UV treatment is that it disinfects water without the use of chemicals. Its primary disadvantage is the lack of residual disinfection.
UV water treatment devices can be used for well water and surface water disinfection. UV treatment compares favorably with other water disinfection systems in terms of cost, labor, and the need for technically trained personnel for operation. Water chlorination treats larger organisms and offers residual disinfection, but these systems are expensive because they need special operator training and a steady supply of a potentially hazardous material. Finally, boiling of water is the most reliable treatment method but it demands labor, and imposes a high economic cost. UV treatment is rapid and, in terms of primary energy use, approximately 20,000 times more efficient than boiling.
