Full Description

This study evaluated the removal of naturally occurring arsenic in a full-scale (106-mgd) conventional treatment plant. When the source water was treated with 3-10 mg/L of ferric chloride or 6, 10, or 20 mg/L of alum, arsenic removal was 81-96 percent (ferric chloride) and 23-71 percent (alum). Metal concentrations in the sludge produced during this study were below the state's current hazardous waste levels at all coagulant dosages. No operational difficulties were encountered. Includes 24 references, tables, figures.
