AWWA JAW26407

Pore and surface diffusion mass transfer models were used to predict the breakthrough profiles of a 14-component mixture eluting from a point-of-use fixed-bed adsorber. The 14 compounds were surrogates, representing a variety of organics from different classes and groups commonly found in contaminated drinking water. Adsorption isotherms were done for all 14 compounds. Polanyi adsorption potential theory was used to correlate single-solute isotherm parameters at 21C and predict isotherm parameters at 6C. Ideal adsorbed solution theory was used in the mass transfer models to correlate the single-solute predicted isotherms at 6C and calculate competitive interactions at the surface of the activated carbon. Includes 27 references, tables, figures.
