Giardia and Cryptosporidium in water: evaluation of two concentration methods and occurrence in wastewater

O Brandonisio et al. Parassitologia. 2000 Dec.

Abstract

Giardia and Cryptosporidium are important agents of water-borne parasitic diseases. In this work we have examined the recovery efficiency of two methods for concentrating Giardia cysts and Cryptosporidium oocysts from water: a membrane filtration method and a crossflow filtration method. Results demonstrated a higher recovery efficiency for crossflow filtration method in comparison to the membrane filtration method. In addition, Giardia cysts and Cryptosporidium oocysts concentration was evaluated in wastewater samples submitted to chemical flocculation or chemical flocculation followed by slow sand filtration. Results showed that slow sand filtration was capable of reducing the number of Giardia cysts, but not of Cryptosporidium oocysts in wastewater.
