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.

Ultraviolet radiation renders bacteria viruses parasites and fungi unable to. A uv water purifier treats micro biologically unsafe water with germicidal ultraviolet light. Uv light does not work to eliminate contaminants such as chlorine heavy metals and voc s volatile organic compounds. This is because the uv radiation is only effective for treating bacteria and viruses.

Municipal water suppliers perform the necessary operations to meet water quality standards. A low pressure mercury arc lamp resembling a fluorescent lamp produces the uv light in the range of 254 manometers nm. 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. How to install a water filter under the sink.

Bulb under sink and ro sterilizer model fltuv110bch 69 99 69 99. Set your store to see local availability add to cart. 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. Express water ultraviolet water filter uv light purifier 12 inch housing with 10 in.

If you drink bacteria infested water the organisms can embed in your digestive tract and replicate. Uvgi is used in a variety of applications such as food air and water purification. 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. Limitations in uv water systems ultraviolet purification itself is not enough to purify water down to drinking water purposes.

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. The shortwave radiation then comes into contact with the parasite bacteria fungi or other microorganism and eliminates it. In general the more time that the water is exposed to the uv radiation the more effective the purification process. 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.

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