This report, Slow Sand Filtration, was prepared by the Task Committee on Slow Sand Filtration of the Water Supply Committee of the Environmental Engineering Division of the American Society of Civil Engineers. With stricter federal regulations concerning the treatment of surface water, communities with small water systems must use some sort of filtration process. Slow sand filters are considered to be appropriate for small systems since the operating procedures and maintenance associated with the process are uncomplicated and not burdensome to them. The purpose of this report is to describe slow sand filtration practice in the United States and to explain the process so that those who design or review and approve these filters will have a solid understanding of the process. The book presents information on the theory of slow sand filtration, with strong emphasis on the biological aspects of the process. Other issues discussed are: 1) Raw water quality appropriate for treatment and concepts for pretreatment; 2) removal of microorganisms; 3) design and operation of slow sand filters; and 4) construction and operating and maintenance costs. Finally, a chapter on pilot plant studies is presented.
