Abstract |
Pilot- and full-scale evaluations of Giardia and Cryptosprodium cyst removal through direction filtration and conventional water treatment were conducted by the Utah Department of Environmental Quality. Cysts were seeded continuously in a step dose at a 0.5 gpm pilot plant and in spike at a 900 gpm full scale plant operated in conventional treatment and direct filtration regimes. Changes in source water quality influenced removal rates more than the mode of treatment in this study. Higher removal rates were consistently observed for Giardia cysts (3.3 log) than for Cryptosporidum oocysts (3.0 log). Two versions of the immunofluorescence staining method were evaluated for their efficiencies in detecting the protozoans in water samples and the results presented in this report. |
