Full Description

Bench-scale experiments determined the germicidal effects of varying dosages of polychromatic ultraviolet (UV) radiation on oocysts of Cryptosporidium parvum. C. parvum oocysts suspended in treated surface water were irradiated with polychromatic light emitted by either a medium-pressure, continuous-wave UV lamp or a pulsed-UV lamp then assayed with human cell culture techniques. Experiments conducted using pulsed-UV doses of greater than or equal to 16 mJ/cm2 provided
