UV Treatment – Alternative Disinfection Method for Chlorinated Well Water

An efficient substitute for chlorinated water for well disinfection is UV (ultraviolet) disinfection. UV disinfection employs ultraviolet light to kill or inactivate coliform bacteria, viruses, and other microorganisms that are present in the water rather than chemicals.

How UV Disinfection Works:

  1. UV Light Source: UV disinfection systems use a UV light source to emit light with a particular wavelength, usually between 254 and 258 nanometers (nm). Microorganisms’ DNA or RNA can be severely disrupted by this wavelength, which prevents them from reproducing and renders them inactive.
  2. UV Chamber: A chamber through which water flows houses the UV light source. The UV light is exposed to the water as it moves through the chamber, essentially curing it.
  3. Disinfection Process: When microorganisms are exposed to UV light, their genetic material (DNA or RNA) absorbs the UV radiation and damages the structure of the germs. The bacteria are rendered harmless as a result of this damage, which stops them from replicating.
