UV Disinfection Kills Germs Chlorine Doesn’t

uv disinfectionWe’ve been hearing a lot about UV disinfection and the many uses for sterilizing air, water and surfaces, but do you know that UV radiation can kill germs that chlorine does not? Ultraviolet (UV) germicidal radiation is a popular method of disinfection in many water and air purification systems, due to it’s highly effective sterilization properties and the many health and safety benefits. UV disinfection is fast, effective and completely safe, providing many advantages over other methods of water disinfection such as chlorination.

In addition to the many benefits of UV sterilization systems, UV light has been proven to eradicate an extensive list of harmful pathogens such as viruses, bacteria and protozoa. One key advantage that UV purification systems offer over chlorine based sterilization methods is the effectiveness of eliminating protozoa such as Cryptosporidium and Giardia which can be chlorine resistant. UV germicidal disinfection has proven to be highly effective at eradicating these parasites from water supplies to prevent widespread intestinal illnesses.

How Does UV Disinfection Work?

UV disinfection works by short wave UV light causing a physical reaction to the RNA and DNA of cells in microorganisms which renders them incapable of reproducing and infecting. UV light is invisible to the human eye, falling in between visible light and X-rays on the electromagnetic spectrum. UV light is emitted by the sun, although most is absorbed by the ozone layer in the Earth’s atmosphere.

UV light is measured in wavelengths referred to as nanometers (nm), which is a billionth of a meter. UV emissions in the UVB and UVC range of 200 to 300 nm are considered germicidal, which means they are effective at inactivating microorganisms such as viruses, bacteria and protozoa. UVC lamps are used in sterilization applications worldwide, providing effective, safe and environmentally friendly disinfection without the use of chemicals and harmful byproducts.

Effectiveness of UV Disinfection

UV disinfection has been proven to be highly effective with instant sterilization of pathogenic organisms such as those that cause hepatitis, cholera, typhoid, polio and viral, intestinal parasitic diseases. UV light provides advantages over sterilization with chlorine with its ability to destroy parasites which threaten public health such as Cryptosporidium and Giardia.

Wastewater treatment facilities utilizing chlorine disinfection systems run the risk of releasing these dangerous organisms into rivers and lakes which may threaten public health if the same water supply is also the source of drinking water. UV disinfection used in drinking water plants helps to eradicate parasites and protozoa resistant to chlorine treatment.

Safety Advantages of UV Disinfection

UV disinfection provides many benefits over other treatment methods, which include the following:

  • UV light is chemical free and does not add any harmful or carcinogenic byproducts to water, air or the surface treated.
  • UV sterilization systems eliminate the need to purchase, handle, store and dispose of corrosive or toxic chemicals, providing environmental benefits to the treatment plant and the community
  • UV light is proven to be extremely effective at eradicating a wide range of harmful microorganisms including pathogens resistant to chlorine treatment
  • UV radiation may be combined with hydrogen peroxide to destroy toxic chemicals while simultaneously providing effective disinfection

It is clear to see why UV light is a popular method of disinfecting water, air and surfaces. Working with an experienced UVC lamp provider will ensure high quality germicidal effectiveness for your application.
