Filtration of 'Giardia' Cysts and Other Substances. Volume 1. Diatomaceous Earth Filtration

摘要

The effectiveness of diatomaceous earth filtration of drinking water was studied under various operating conditions for removal of Giardia cysts, total coliform bacteria, standard plate count bacteria, turbidity, and particles. Seven grades of diatomaceous earth were used. Temperatures ranged from 5 to 19C, and concentrations of Giardia cysts and bacteria were varied over two or more log cycles. Diatomaceous earth filtration is an effective process for water treatment.
