Principle of disinfection by UV radiation
UV-C water disinfection systems use special lamps that emit UVC light. These have a particular wavelength capable of disrupting the DNA of microorganisms.
These UV light waves are also called “spectrum” or “germicidal frequency”.
The frequency used in killing microorganisms is 254 nanometers (nm).
When water passes through a UV water treatment system:
- the rays produced by the lamps reach the pathogenic microorganisms that pass by. These UV lamps contained in a reactor are usually made of stainless steel.
- They are exposed to a lethal dose of UVC light that attacks the DNA, thus eliminating the ability of the microorganism to reproduce.
- Thanks to this process, it cannot replicate itself or infect other organisms with which it comes into contact.
This process of exposing water to UV light is simple and effective, killing 99.99% of harmful microorganisms without adding chemicals to the water. In addition, it is a safe method that creates no harmful chemical by-products.
