AWWA ACE58107

The use of rapid small scale column tests (RSSCTs) initially designed for simulating removalof organic compounds by granular activated carbon was extended in this study for arsenateadsorption onto GFH. Adsorption kinetic studies and comparison of laboratory RSSCTperformance versus pilot-scale performance suggests that proportional diffusivity (PD) RSSCTscaling approaches are more valid than constant diffusivity (CD) approaches for arsenate ontoGFH. All the RSSCTs captured changes in water quality (source water, pH) and operationalregimes (e.g., EBCTs) and could be used to aid in selection and design of arsenic removal mediafor full-scale treatment facilities.
