Studies have shown that ultraviolet light (UV) can penetrate cells and debilitate DNA, thereby destroying an organism’s ability to reproduce. Such a discovery has paved the way for the development of ultraviolet disinfection technology. UV light is characterized by a wavelength of less than 400 nanometers.

In general, contaminants removed with use of UV-system include: microbial; nevertheless. UV systems may be coupled with a pre-filter to extricate larger organisms and particulates with attached bacteria. lUV units are used as individual treatment systems or as parts of other purification processes.

Within the Department of Civil, Environmental, and Architectural Engineering at the University of Colorado Boulder, Dr. Karl Linden and his research team focus on this issue.
