A previously presented microcolumn scale-up procedure is evaluated. Scale-up assumptions that involve equal capacities in microcolumns and field columns are studied in an effort to determine whether preloading activated carbon with a natural water significantly reduces the carbon's capacity for a target compound. The capacities observed in the column studies are compared with isotherms for distilled-deionized water, groundwater, and groundwater with preloaded carbon. Total organic carbon breakthrough in the field column is presented to explain capacity reductions. A simplified version of a mass transfer model and a more complex model are used to predict the pilot-column results. Includes 33 references, tables, figures.
