Ultraviolet - Research, Results And Facts

Germicidal UV has been used in water disinfection systems for many years. As stated by the American Water Works Association, "... UV light disinfection process does not use chemicals. Microorganisms, including bacteria, viruses, and algae, are inactivated within seconds of UV light disinfection... Ultraviolet is effective in inactivating Cryptosporidium, while at the same time decreasing chlorinated disinfection by-products... U.S. cities currently using or planning to use UV light water disinfection include:
Seattle, Washington, New York City, Central Lake County, Illinois, Albany, New York, Tempe, Arizona ..."

The Application of Ultraviolet Germicidal Irradiation to Control Transmission of Airborne Disease: Bioterrorism Countermeasure

Ultraviolet Germicidal Irradiation - UVGI - is a common tool in laboratories and health care facilities, but is not familiar to the public, or to some heating, ventilation, and air conditioning engineers. Interest in UVGI is increasing as concern about a possible malicious release of bioterror agents mounts. Recent applications of UVGI have focused on control of tuberculosis transmission, but a wide range of airborne respiratory pathogens are susceptible to deactivation by UVGI.

Public Health Reports published an article titled "The Application of Ultraviolet Germicidal Irradiation to Control Transmission of Airborne Disease: Bioterrorism Countermeasure". The article is in Volume 118, Issue Number 2, March/April 2003. In this article, the authors provide an overview of air disinfection technologies, and an in-depth analysis of UVGI, its history, applications, and effectiveness.
