UV Water Purification and How it Works
The UV water disinfection process utilizes special UV lamps or bulbs that emit UV light of a particular wavelength. These UV light waves have the ability, based on their length, to disrupt the DNA of microorganisms. These UV light waves are referred to as the Germicidal Spectrum or Frequency, the frequency used in killing micro-organisms is 254 ...
