benefit of using UV disinfection

A common component of whole-home water treatment systems is UV disinfection. While the rest of the system may be designed for iron, sulphur, manganese, sediment, chlorine/chloramine, and removal of other contaminants, it is not effective at removing protozoa, viruses, and bacteria. The addition of a UV disinfection component provides an extra level of water quality and peace of mind and is often recommended for households on well water or those on water supplies with questionable disinfection or ones where frequent problems with disinfection occur.

  • How does UV disinfection work? The germicidal wavelength of UV light renders micro-organisms incapable of reproducing or infecting others by damaging their nucleic acids. They can no longer cause gastrointestinal or other problems. In addition, UV disinfection also destroys some chemical contaminants in water, such as industrial solvents, pesticides, and pharmaceuticals.
  • What is the benefit of using UV disinfection? Many choose UV disinfection because it is a non-chemical process. In addition, it won’t leave behind residuals like some other methods, so you won’t be swapping one contaminant for another. It is also more effective in that it can inactivate chlorine-resistant pathogens such as giardia and cryptosporidium. Another benefit is that you won’t have to deal with the chemicals used in a chemical-based disinfection system or their corrosive nature.
