Enhanced coagulation for arsenic removal
Preliminary bench‐ and pilot‐scale investigations showed that coagulation is a promising treatment for removing arsenic from drinking water but that further work is needed, primarily on full‐scale plants.
The possible use of enhanced coagulation for arsenic removal was examined at the facilities of a California utility in 1992 and 1993. The tests 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 investigators 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.
