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.

Uv radiation for water purification.

Set your store to see local availability add to cart. 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. 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. 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.

If you drink bacteria infested water the organisms can embed in your digestive tract and replicate. How to install a water filter under the sink. A low pressure mercury arc lamp resembling a fluorescent lamp produces the uv light in the range of 254 manometers nm. The shortwave radiation then comes into contact with the parasite bacteria fungi or other microorganism and eliminates it.

But uv purification systems take water purification to a higher level providing a safe solution against chlorine resistant microorganisms such as giardia and cryptosporidium which cause thousands of documented health cases each year. A uv water purifier treats micro biologically unsafe water with germicidal ultraviolet light. This is because the uv radiation is only effective for treating bacteria and viruses. Bulb under sink and ro sterilizer model fltuv110bch 69 99 69 99.

Uv light does not work to eliminate contaminants such as chlorine heavy metals and voc s volatile organic compounds. Ultraviolet radiation renders bacteria viruses parasites and fungi unable to. Principles of uv disinfection home water treatment uv radiation has three wavelength zones. Uv a uv b and uv c and it is this last region the shortwave uv c that has germicidal properties for disinfection.

Municipal water suppliers perform the necessary operations to meet water quality standards. In general the more time that the water is exposed to the uv radiation the more effective the purification process. 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.

1 advantages of ultraviolet water purification. So technically yes a longer unit would allow more time for the water to pass through the uv lights thus allowing for more exposure.
