Uv Radiation For Water Purification

Principles of uv disinfection home water treatment uv radiation has three wavelength zones.

Uv radiation for water purification.

The uv wavelength scrambles the dna of living organisms in the water so they can no longer reproduce and make you sick. A low pressure mercury arc lamp resembling a fluorescent lamp produces the uv light in the range of 254 manometers nm. Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions. 1 advantages of ultraviolet water purification.

Uv a uv b and uv c and it is this last region the shortwave uv c that has germicidal properties for disinfection. Uv water purification can be used to treat water whether it s from a municipal water supply a drinking water well lake or a spring. In general the more time that the water is exposed to the uv radiation the more effective the purification process. The shortwave radiation then comes into contact with the parasite bacteria fungi or other microorganism and eliminates it.

Limitations in uv water systems ultraviolet purification itself is not enough to purify water down to drinking water purposes. Uvgi is used in a variety of applications such as food air and water purification. How to install a water filter under the sink. So technically yes a longer unit would allow more time for the water to pass through the uv lights thus allowing for more exposure.

Uv radiation is so effective that it can eliminate up to 99 99 of bacteria and viruses including those associated with water borne illnesses such as typhoid gastroenteritis hepatitis flu and cholera. Bulb under sink and ro sterilizer model fltuv110bch 69 99 69 99. Municipal water suppliers perform the necessary operations to meet water quality standards. If you drink bacteria infested water the organisms can embed in your digestive tract and replicate.

Ultraviolet uv water treatment works by exposing microorganisms such as cryptosporidium giardia lamblia and more to uv radiation via a special uv light bulb which disrupts their dna and disables their ability to replicate. A uv water purifier treats micro biologically unsafe water with germicidal ultraviolet light. Set your store to see local availability add to cart. Uv light does not work to eliminate contaminants such as chlorine heavy metals and voc s volatile organic compounds.

Essentially ultraviolet light is produced by means of a germicidal or mercury vapor lamp made with glass that allows the optimal shortwave ultraviolet light a fully transparent surface through which to pass. Ultraviolet radiation renders bacteria viruses parasites and fungi unable to.
