What is UV-C Technology


  • UV-C water purification is one of the most effective methods for disinfecting water. This process uses special "germicidal" UV-C lamps that emit high-intensity ultraviolet light to purify the water without using harsh chemicals that are harmful to the environment.

What is ultraviolet radiation and how does it work:

  • UV radiation is the area of the electromagnetic spectrum between X-rays and visible light
  • The most common source of UV radiation is sunlight, which releases three types of UV rays:

Facts to remember: 

  • UVA photons have the longest wavelengths, whilst UVB and UVC rays have the shortest wavelengths.
  • While UVA and UVB rays flow through the atmosphere, all UVC and some UVB photons are absorbed by the Earth's ozone layer. As a result, UVA makes up the vast majority of UV rays you encounter, with only a small percentage of UVB.

Its Uses:

  • UV rays are frequently used to kill bacteria and other microorganisms.
  • UV-C (ultraviolet germicidal irradiation) is a disinfectant treatment that kills or inactivates bacteria by damaging their nucleic acids and changing their DNA, rendering them unable to perform critical biological jobs and stopping their replication.
  • UVGI is used to disinfect a variety of surfaces, including food, air, and water.
  • Is it safe for human consumption?
  • According to the researchers, the device was intended solely to disinfect non-living items. As a result, the UV-C radiation used in this device could harm the skin and eyes of living beings.
