Description	Volumetric liquid-side mass transfer coeffcient kLa was measured in the upflow ejector (with and without swirl) and in the cocurrent ejector}distributor bubble column as well as gas and liquid phase backmixing in the column. Water and 0.3M aqueous solution of Na2SO4 were used to simulate coalescent and non-coalescent batches. Different methods were used to measure kLa: dynamic pressure-step (DPM), steady-state physical (SPM), classic sul%22te (CSM) and steady-state sulfite method (SSM). Pure oxygen and air were used as the gas phase. Large intensity of liquid mixing in the column caused by the jet with high kinetic energy was confirmed. Gas backmixing in the coalescent batch was well described by the axial dispersion model while gas backmixing in the non-coalescent batch was successfully described by the model of two parallel series of four perfect mixers with backflow, where the respective branches corresponded to the small and large bubbles present in the dispersion, was therefore proposed.
