A previously proposed microcolumn scale-up procedure is evaluated. Scale-up assumptions dealing with equal capacities in microcolumns and field columns are focused on in an effort to evaluate the effect of preloading carbon with naturally occurring organic material. Reductions in capacity found in the column studies are compared to distilled, groundwater, and pre-adsorbed isotherms. 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 mass transfer model are used to predict the pilot column results.
