The hydrodynamic characteristics of an air-lift activated carbon slurry column with external looping were investigated to find the optimal operating conditions of the slurry adsorption process that is frequently used as wastewater treatment, biological air pollutant removal and other environmental treatments. The experiments were conducted at different concentrations of adsorbents and gas inputs in the air-lift bubble column having external looping as batchwise contactor. The hydrodynamic behaviors were estimated with the residence time tracing of slurry adsorbents and gas holdups. The mixing characteristics were analyzed to find the best operating condition of an air-lift bubble column for the adsorbing equipment, and the performance of column was compared with that of internal looping.
