Description:
This investigation involved operating a pilot granular activated carbon (GAC) plant to obtain capacity data under typical field conditions, determining isotherms for selected synthetic organic chemicals, and comparing the capacity predicted by the isotherm data with the pilot-plant capacity data. The pilot-plant GAC capacitiesat saturation for empty bed contact times of 2.5 to 5.0 min were within a factor of 2.5 of the isotherm capacities. This is reasonably good agreement, considering that the displacement effects that take place in the GAC columns are not accounted for in the isotherm calculations.
