The Basics of UV Disinfection 26-10-2018

Disinfection with sunlight has been recognized for centuries. The germicidal properties of sunlight were demonstrated by Downes and Blunt in 1877. Once it was understood that specific UV-C wavelengths are responsible for this germicidal activity, the technology was developed so that UV light could be used in a controlled and meaningful way. Today, UV Systems are used extensively across Australia providing reliable disinfection for potable water, process water and healthcare water supplies.

UV technology is easy to implement

Ultraviolet light is a sophisticated disinfection solution, but it doesn’t require an overly technical explanation. Light of a specific wavelength is passed through the water, inactivating any pathogens that are present. Because they are inactivated, microbes can no longer multiply, which means they cant cause infection.


  • UV does not alter taste, odour, colour or pH of the water
  • UV does not require the addition of chemicals
  • UV does not impart toxic by-products into the water
  • UV systems are compact and easy to install
  • UV systems require very little maintenance
  • Running costs are often lower than those of a household lightbulb
