The paper contains the results of experimental study of air–water and air–polymer aqueous solutions atomization process in modified spray tower. The experiments on hydrodynamic characteristics in the spray column with geometrically modified confusors for water and high-molecular polymer aqueous solutions as well as on mass transfer in aeration process, have been carried out. The major running cost derived from the operation of various mass exchangers is pressure drop. It has been shown that for geometrically modified confusors with profiled inside surfaces and double profiled inside surfaces the pressure drop is smaller than in the case of classical construction. Aeration process was studied for water flow in the co-current spray column with closed circulation liquid flow. It has been shown that independently from the applied geometry of modified confusor at given gas and liquid volume rates the aeration degrees were comparable. Taking into account the considerable decrease of flow resistance in comparison with classical construction it is reasonable to recommend the modified solution for realization the aeration process.
