The following data were obtained in a laboratory study conducted for the determination of the overall volumetric mass transfer coefficient in a packed bed air stripping unit with a diameter of 1 m and a height of 4m equipped with 4 equidistant sampling ports along its height. Contaminated groundwater containing an initial TCE concentration of 230 mg/l was fed to the stripping column at 1 m³/m²×min. The air to liquid ratio was 100. Based on the data determine K_La (s^-1). Henry’s constant for TCE is 0.428.
