AWWA ACE61770

This study primarily focuses arsenic removal performance of commercially available iron-based sorbents: GFH and E33, iron-aluminum based AAFS-50. Rapid small-scale column tests (RSSCTs) were used to evaluate the performance using groundwater of Arizona. Comparison of the breakthrough curves of full-scale and RSSCTs suggests that RSSCTs simulated full-scale systems reasonably well. The breakthrough curves of silica, total phosphorus, and total vanadium were also monitored and presented for GFH, E33 and AAFS-50 in this study. Includes 11 references, table, figures.
