Uv radiation for water purification.

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. In general the more time that the water is exposed to the uv radiation the more effective the purification process. 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. 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.

Uv a uv b and uv c and it is this last region the shortwave uv c that has germicidal properties for disinfection. Uv light does not work to eliminate contaminants such as chlorine heavy metals and voc s volatile organic compounds. Set your store to see local availability add to cart. Uvgi is used in a variety of applications such as food air and water purification.

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. Express water ultraviolet water filter uv light purifier 12 inch housing with 10 in. 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 water purification can be used to treat water whether it s from a municipal water supply a drinking water well lake or a spring. 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. A low pressure mercury arc lamp resembling a fluorescent lamp produces the uv light in the range of 254 manometers nm. Ultraviolet radiation renders bacteria viruses parasites and fungi unable to.

A uv water purifier treats micro biologically unsafe water with germicidal ultraviolet light. If you drink bacteria infested water the organisms can embed in your digestive tract and replicate. The shortwave radiation then comes into contact with the parasite bacteria fungi or other microorganism and eliminates it. 1 advantages of ultraviolet water purification.

This is because the uv radiation is only effective for treating bacteria and viruses. The uv wavelength scrambles the dna of living organisms in the water so they can no longer reproduce and make you sick.
