What is an Ultraviolet Water System and How Does it Work?

Ultraviolet (UV) Water Purification Systems remove contaminants from untreated water using a physical and chemical-free process. Electromagnetic radiation decontaminates the water, freeing it of chemicals, bacteria and other materials, including:

  • Cryptosporidium
  • Giardia
  • Chlorine
  • Chloramine
  • Viruses
  • Salmonella
  • coli
  • Meningitis
  • Dysentery
  • Flu
  • Cysts

Germicidal or mercury vapour lamps create UV light. A glass component of the lamp creates a transparent surface for the shortwave UV light to pass through. Shortwave radiation can reduce or eliminate encountered bacteria and microorganisms.

Although highly effective, UV disinfection doesn’t remove dissolved organics, inorganic compounds or particles in the water. UV water systems are commonly used to treat surface and well water. It also tends to compare favourably with other water disinfection systems in regard to cost, labour and user-friendly operation. UV water treatment is quick, energy-efficient, and approximately 20,000 times more effective than boiling water.
