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.

Uv radiation for 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. In general the more time that the water is exposed to the uv radiation the more effective the purification process. Principles of uv disinfection home water treatment uv radiation has three wavelength zones. This is because the uv radiation is only effective for treating bacteria and viruses.

Uv a uv b and uv c and it is this last region the shortwave uv c that has germicidal properties for disinfection. 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. 1 advantages of ultraviolet water purification. How to install a water filter under the sink.

Municipal water suppliers perform the necessary operations to meet water quality standards. Set your store to see local availability add to cart.

Limitations in uv water systems ultraviolet purification itself is not enough to purify water down to drinking water purposes. 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 low pressure mercury arc lamp resembling a fluorescent lamp produces the uv light in the range of 254 manometers nm. The uv wavelength scrambles the dna of living organisms in the water so they can no longer reproduce and make you sick.

The shortwave radiation then comes into contact with the parasite bacteria fungi or other microorganism and eliminates it. 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. 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.

Ultraviolet radiation renders bacteria viruses parasites and fungi unable to. Uvgi is used in a variety of applications such as food air and water purification.
