Abstract
The possible use of enhanced coagulation for arsenic removal was exami ned at the facilities of a California utility in 1992 and 1993. The te sts were conducted at bench, pilot, and demonstration scales, with two source waters. Alum and ferric chloride, with cationic polymer, were investigated at various influent arsenic concentrations. The investiga tors concluded that for the source waters tested, enhanced coagulation could be effective for arsenic removal and that less ferric chloride than alum, on a weight basis, is needed to achieve the same removal.
