摘要：

Water samples, taken from the intake and rapid filter system of a water purification plant, were analyzed using an immunofluorescence antibody method for detecting the presence of Giardia cysts and Cryptosporidium oocysts. Giardia cysts and Cryptosporidium oocysts were found in the intake water from zero to 38.7 cysts/100 l and 1.7-50.5 oocysts/100 l with averages of 9.6 cysts/100 l and 19.4 oocysts/100 l. Giardia cysts and Cryptosporidium oocysts were also detected in the samples taken from the rapid filtration unit with mean concentrations of zero to 2.3 cysts/100 l and 0-2.5 oocysts/100 l, respectively. The efficacy of the rapid filter in suspended material and (oo)cyst removal was significant. The removal late was 56-97% for suspended material and 69-100% for the (oo)cysts.
