UV radiation can be used for multiple purposes in water and air treatment, but is primarily employed as a disinfection process that inactivates micro -organisms without chemicals. For other applications, UV is used for the removal of organic and inorganic chemicals, including chlorine, chloramines, ozone and Total Organic Carbon (TOC) emerging contaminants.
UVC radiation is known to break the DNA of bacteria, viruses and spores. As a result, they are rendered harmless.
Ultra-Violet (UV) light is invisible to human eyes. It can be subdivided into three categories: UVA, UVB and UVC. UV-A from 315 - 400nm UV-B from 280 - 315nm UV-C from 100 - 280nm.
