INACTIVATION OF "GIARDIA MURIS" CYSTS USING MEDIUM-PRESSURE ULTRAVIOLET RADIATION ON FILTERED DRINKING WATER

BOLTON J. R. / CRAIK S. A. / FINCH G. R. / et al. - ARTICLE DE PERIODIQUE - 2000

Inactivation of Giardia muris by Ultraviolet radiation. Cyst removal by medium pressure UV light was studied on filtered surface water. UV doses between 5 and 83 mJ/cm2 were applied and give 2 - 3 log unit reduction in infectivity. Mechanisms of inactivation of Giardia were approached. This treatment seems to be an alternative to conventional chemical disinfection processes.
