METHOD FOR INACTIVATION OF CRYPTOSPORIDIUM PARVUM AND GIARDIA MURIS USING ULTRAVIOLET LIGHT

摘要

PPROBLEM TO BE SOLVED: To provide a method effective in cost reduction in sterilizing drinking water which might contain Cryptosporidium oocysts using ultraviolet light. PSOLUTION: The method for the inactivation of Cryptosporidium oocysts, Gardia cysts, and similar microorganisms comprising irradiating the drinking water containing those microorganisms with continuous ultraviolet light having predominant wavelength bands that falls within about 200 nm to about 300 nm with a dose from about 1 mJ/cmSP2/SPto about 175 mJ/cmSP2/SP.
