This paper evaluates direct filtration as a treatment method for water from five sources in Virginia. The most effective filtration scheme consisted of a three-minute rapid mix with alum and a cationic polymer used in combination as primary coagulants. Raw water quality, head loss, algal concentrations, effects of coagulant choice, hydraulic loading, filter media configurations, and effects of flocculation are covered. Includes 29 references, tables, figures.
