Abstract

Delineates conditions that have contributed to or permitted passage of Giardia cysts by the rapid-rate filtration process. Evaluates applicability to full-scale operation of the findings of pilot-scale studies of rapid-rate filtration (with special reference to low-turbidity water). Also evaluates startup and operation of a newly constructed slow sand filtration system in a watershed known to contain a persistent source of Giardia cysts. Published in 1988.
