Abstract
Evaluates the ability of full-scale filtration systems (rapid sand, dual media, and diatomaceous earth) operating under ambient conditions to remove Giardia cysts and cyst-size particulates. Provides design and operation guidelines for maximizing cyst removal and verifies findings of previous laboratory and pilot-plant studies on cyst-removal techniques. Published in 1989.
