2. Ultraviolet germicidal irradiation - Wikipedia

   en.wikipedia.org/wiki/Ultraviolet_germicidal...

   UV treatment compares favourably with other water disinfection systems in terms of cost, labour 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 ...

3. Catskill-Delaware Water Ultraviolet Disinfection Facility

   en.wikipedia.org/wiki/Catskill-Delaware_Water...

   The Catskill-Delaware Water Ultraviolet Disinfection Facility is a 160,000-square-foot (15,000 m 2) ultraviolet (UV) water disinfection plant built in Westchester County, New York to disinfect water for the New York City water supply system. [1] The compound is the largest ultraviolet germicidal irradiation plant in the world. [2]

4. Solar water disinfection - Wikipedia

   en.wikipedia.org/wiki/Solar_water_disinfection

   A second approach uses stored solar electricity from a battery, and operates at night or at low light levels to power an ultraviolet lamp to perform secondary solar ultraviolet water disinfection. Solar thermal water disinfection uses heat from the sun to heat water to 70–100 °C for a short period of time. A number of approaches exist.

5. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light's disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no ...

6. Germicidal lamp - Wikipedia

   en.wikipedia.org/wiki/Germicidal_lamp

   A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoans.
