The Cryptosporidium Story: 25th Anniversary of the Discovery that Cryptosporidium Undergoes Ultraviolet Inactivation at Low UV Doses
By James R. Bolton, Bolton Photosciences Prior to 1998, ultraviolet (UV) disinfection of drinking water was not popular because of a perception that UV treatment was not effective for waters contaminated with protozoa, such as Cryptosporidium, and did not seem to have equivalent advantages as chlorination and ozonation. In 1997-1998, a group of dedicated scientists and … [Read more...] about The Cryptosporidium Story: 25th Anniversary of the Discovery that Cryptosporidium Undergoes Ultraviolet Inactivation at Low UV Doses
