What Is UV? Although we can't see UV light, we are exposed to a small amount every time we step out into the sun. In fact, UV light is responsible for sunburns. The water treatment industry uses special lamps that emit UV light of a particular wavelength in order to disinfect water. UV light works by attacking the genetic core (DNA) of bacteria and viruses, destroying their ability to function and reproduce. The process is simple but effective: our systems destroy 99.99 percent of harmful microorganisms without adding chemicals or changing your water's taste or odor. From Wikipedia.org - Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the...
