Ultraviolet light (UV) water purification systems can be an effective bacterial control and water sanitizing technology.
UV (Ultraviolet Light) Water Filtration
ULTRAVIOLET LIGHT (UV) WATER FILTRATION
If you have a private well and your water test shows bacteria present, UV technology may work you.. City water supplies typically dose chlorine or a chlorine compound (chloramine) to provide bacterial and or microbial disinfection. While this may impart an objectionable taste or odor to the water, it is a necessary step for safety’s sake. They may also use ozonation and other technologies at the treatment plant before distribution.
With a private well, you are on your own in protecting your water supply. A water test should always be your first step before determining what type of system, if any, should be installed. For purposes of bacterial or microbial disinfection, Ultraviolet light (UV) water filtration systems are very effective. However, you must take into account other aspects of the water quality that may affect Ultraviolet light (UV) effectiveness.
HOW DOES ULTRAVIOLET (UV) LIGHT WORK TO DISINFECT THE WATER SUPPLY
UV is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun. In fact, UV light is responsible for causing sunburns. Ultraviolet systems use special lamps or bulbs that emit UV light of a particular wavelength. The Ultraviolet energy attacks the genetic core of the microorganism and rearranges the DNA /RNA eliminating the microorganism’s ability to function and reproduce. If the microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact. The process is simple but effective, destroying 99.99% of harmful microorganisms without adding chemicals to the water.
