Uv Minimises Risk From Cryptosporidium

摘要

Ultraviolet (UV) light is increasingly being used as an effective barrier for Cryptosporidium and other emerging (chlorine resistant) organisms in the United Kingdom. Many water companies are now using this technology to ensure water leaving the treatment plant doesn't pose a risk to health. This article examines the history of UV disinfection, reviews a number of Cryptosporidium outbreaks in the UK, and illustrates some of the advances now being made in the design of UV technology, including use of computational fluid dynamics (CFD) and validation of system performance to enhance its effectiveness.
