UV rays are part of the light spectrum, along with cosmic rays, gamma rays, x-rays, visible light, infrared, and radio waves.
There are three UV wavelength ranges: UV-C runs from 100 nanometers (nm) to 280 nm, UV-B runs from 280 to 315 nm, and UV-A runs from 315 to 400 nm.
UV-C light deactivates the DNA of bacteria, viruses, and other pathogens, destroying their ability to multiply and cause disease. UV-C light damages the nucleic acid of bacteria and viruses by forming covalent bonds between certain adjacent bases in DNA. As a result, the DNA cannot be unzipped for replication, and the organism is unable to reproduce. In fact, if it attempts to replicate, it dies.
UV-C technology uses no chemicals to disinfect water, air, and surfaces. It is easy, inexpensive, and requires very little maintenance.
Most fountains recycle the same tank of water. To prevent microbes from breeding and growing, we have to change the water frequently. That may make the fountain less convenient for most of us. Therefore, integrating a UV-C light is a very efficient and maintenance-free solution!
