  2. Ultraviolet germicidal irradiation - Wikipedia

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

    Using UV light for disinfection of drinking water dates back to 1910 in Marseille, France. [61] The prototype plant was shut down after a short time due to poor reliability. In 1955, UV water treatment systems were applied in Austria and Switzerland; by 1985 about 1,500 plants were employed in Europe.

  3. Germicidal lamp - Wikipedia

    en.wikipedia.org/wiki/Germicidal_lamp

    In this application, the light produced by the lamp is usually filtered to remove as much visible light as possible, leaving just the UV light. Germicidal lamps are also used in waste water treatment in order to kill microorganisms. An EPROM. The small quartz window allows UV light to enter during erasure.

  4. 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 ...

  5. Portable water purification - Wikipedia

    en.wikipedia.org/wiki/Portable_water_purification

    UV-treated water must therefore not be exposed to visible light for any significant period of time after UV treatment, before consumption, to avoid ingesting reactivated and dangerous microbes. Recent developments in semiconductor technology allows for the development of UV-C Light Emitting Diodes (LEDs). UV-C LED systems address disadvantages ...

  6. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect. [25]

  7. Catskill-Delaware Water Ultraviolet Disinfection Facility

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

    The UV facility treats water delivered by two of the city's aqueduct systems, the Catskill Aqueduct and the Delaware Aqueduct, via the Kensico Reservoir. [3] (The city's third supply system, the New Croton Aqueduct, has a separate treatment plant. [4]) The plant has 56 energy-efficient UV reactors, and cost the city $1.6 billion.
