Ultraviolet or “UV” is a type of energy found in the electromagnetic spectrum lying between x-rays and visible light. Ultraviolet is divided into four basic sections: UV-V, UV-A, UV-B and UV-C. It is the UV-C, or germicidal UV, specifically the 265nm wavelength of UV-C that offers disinfection. The ultraviolet energy attacks the genetic core of the harmful microorganism and rearranges the DNA/RNA preventing reproduction. If the microbe can not replicate, it cannot infect! UV is quick and the most cost effective way to disinfect your water.
