Ultraviolet Light Ozone Generators - BoiE

Ultraviolet (UV) Light Ozone Generators use low pressure UV lamps that generate multiwavelength UV light with two peaks, one at the 254-nm light band and another at 185-nm. The 185-nm light produces ozone through photolysis of oxygen molecules, while the 254-nm light photolyzes ozone back into oxygen, which works against the ozone production ...

Ozone layer and ultra-violet radiation | Copernicus

Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called 'good' ozone. This in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

Ozone - Wikipedia

Ozone (/ ˈ oʊ z oʊ n /), or trioxygen, is an inorganic molecule with the chemical formula O 3.It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down in the lower atmosphere to O 2 ().Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the ...

Sunlight, UV radiation, and ozone | Dr. Ken Dembny

Jun 28, 2019 · Sunlight contains all three types of UV radiation: UVC, UVB, and UVA. The ozone layer protects humans from UVC radiation, which would otherwise destroy the skin; but the ozone layer does not protect against UVB or UVA radiation.

How does ozone absorb UV light? - University of Surrey

Because it needs short wavelength ultraviolet light and much of this is scattered by the Earth's atmosphere, ozone cannot be formed below an altitude of about 20 km. Above an altitude of about 50 km the density of the atmosphere is too little to allow ozone to be formed.

Germicidal lamp - Wikipedia

A germicidal 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 protozoa.It can also be used to produce ozone for water disinfection. They are used in ultraviolet germicidal irradiation (UVGI).

1. When using ultraviolet rays, people, plants, and animals must leave the scene! Prolonged exposure to ultraviolet light can burn people's eyes and skin. 2. Under normal circumstances, disinfection twice a week, about 30 ~ 60 minutes each time; if there are many bacteria or large space, please increase the number of disinfection appropriately. 3. After using the UV lamp for a period of time ...

Pulsed xenon lamps: These lamps, which emit a short pulse of broad spectrum (including UV, visible and infrared) light have been filtered to emit mainly UVC radiation and are sometimes employed in...

Ozone vs UV - Ultraviolet Pools

Ozone gas that is generated by ultraviolet light or by corona discharge and is dissolved in water to kill microorganisms, destroy organics, and break down chloramines by oxidation. Due to it’s instability, it is short lived and reverts back to oxygen (02) shortly after it enters the water flow.

Ozone Water Treatment - UV Ozone Destruct

Germicidal ultraviolet light destroys Ozone in water very quickly. Therefore, the 254 nm wavelength produced by low- pressure germicidal UV lamps is quite effective for ozone removal from water. The mechanism for removing ozone is dissociation, which occurs when 254 nm UV energy “breaks” one of the oxygen bonds in an ozone molecule.

What is the difference between ozone and ultraviolet ...

Feb 25, 2019 · At wavelengths between 220-280 nanometers, UV acts as a disinfectant and is generally referred to as "UV-C". The optimum wavelength for UV-C is 254nm. Ultraviolet light at wavelengths between 180-220nm is called "UV-V" and interacts with atmospheric oxygen (O2) to produce relatively low concentrations of ozone (O3).
