Alternative filtration methods for removal of Giardia cysts and cyst models
The recent occurrence of waterborne giardiasis outbreaks has spurred renewed interest in water filtration for cyst removal. Studies with cyst models and Giardia muris cysts suggest that properly operated water filtration plants should be able to remove a high percentage of G. lamblia cysts. For effective cyst removal, diatomaceous earth (DE) filters need 1.0 kg/m2 diatomite precoat plus body feed, and granular media filters require coagulation of raw water and production of filtered turbidity well below 1.0 ntu throughout the entire filter run.
