Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
-253.7nm can kill bacteria and viruses as well as microorganisms such as cyanobacteria and chlorophyta in water.
-185.0nm can photolyze COD in water and purify water quality.
Don’t look at the UV lamp directly when the UV lamp is igniting. Don’t irradiate the skin with UV-lamp. Hold a piece of ordinary glass before your eyes when you need to look at the UV-lamp. Please keep the surface of the tube clean to prevent the dust or the dirt from affecting the ultraviolet ray’s output. Please don’t touch the quartz glass with bare hands while installing the lamp and using it. The quartz glass can be cleaned by using alcohol tampon.

The frequency used in killing micro-organisms is 254 nanometers (nm). Ultraviolet Water Treatment Systems use a lamp that creates these UV waves lengths. As water passes through a UV water treatment system, living organisms are exposed to the UV light and the living organisms effectually killing them
