2. Ultraviolet germicidal irradiation - Wikipedia

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

   A low-pressure mercury-vapor discharge tube floods the inside of a biosafety cabinet with shortwave UV light when not in use, killing microbes on irradiated surfaces. Ultraviolet germicidal irradiation (UVGI) is a disinfection technique employing ultraviolet (UV) light, particularly UV-C (180–280 nm), to kill or inactivate microorganisms.

3. Germicidal lamp - Wikipedia

   en.wikipedia.org/wiki/Germicidal_lamp

   Germicidal lamp. A 9W germicidal lamp in a modern compact fluorescent lamp form factor. Glow of a germicidal lamp excited by a high voltage probe. Close-up of the electrodes and the safety warning. A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light.

4. Portable water purification - Wikipedia

   en.wikipedia.org/wiki/Portable_water_purification

   Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) for drinking purposes. Their main function is to eliminate pathogens, and often also of suspended solids and some unpalatable or toxic compounds. These units provide an autonomous supply ...

5. Catskill-Delaware Water Ultraviolet Disinfection Facility

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

   Trojan Technologies. 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.

6. Far-UVC - Wikipedia

   en.wikipedia.org/wiki/Far-UVC

   Far-UVC is a type of ultraviolet germicidal irradiation being studied and commercially developed for its combination of pathogen inactivation properties and reduced negative effects on human health when used within exposure guidelines. [1][2][3][4] Far-UVC (200-235 nm), while part of the broader UV-C spectrum (100-280 nm), is distinguished by ...

7. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   Disinfection by means of ultraviolet (UV) lamps (sometimes called germicidal or bactericidal) may be employed to sterilize pathogens that evade the RO process. Chlorination or chloramination (chlorine and ammonia) protects against pathogens that may have lodged in the distribution system downstream. [29]
