Filtration as a Barrier to Passage of Cysts in Drinking Water
Numerous outbreaks of waterborne giardiasis have occurred in the United States since 1973. Generally, the causes have been inadequate disinfection or inadequate filtration (perhaps none), or sometimes both. Even though research on water filtration for Giardia cyst removal is expected to continue in the future, sufficient information on water filtration for cyst removal is available now to provide some guidance for engineers who design filtration plants and for operators who run them.
