The primary objective of this study was to improve the current methodology for concentrating, recovering, and detecting cysts of Giardia lamblia in water supplies. Two sampling processes for the concentration of cysts were examined. One process was diatomaceous earth filtration while the second was that of cyst concentration onto charged particles. Cysts of G. muris were used to determine the retention efficiency of ion-exchange resins and each type of diatomaceous earth filter examined. Cyst desorption efficiencies were evaluated for ion-exchange resins that best retained cysts, while backwashing parameters were optimized for diatomaceous earth filters.
