The use of rapid small scale column tests (RSSCTs) initially designed for simulating removal
of organic compounds by granular activated carbon was extended in this study for arsenate
adsorption onto GFH. Adsorption kinetic studies and comparison of laboratory RSSCT
performance versus pilot-scale performance suggests that proportional diffusivity (PD) RSSCT
scaling approaches are more valid than constant diffusivity (CD) approaches for arsenate onto
GFH. All the RSSCTs captured changes in water quality (source water, pH) and operational
regimes (e.g., EBCTs) and could be used to aid in selection and design of arsenic removal media
for full-scale treatment facilities. Includes 15 references, figure.
