Each group of indivisible dependent elements always contains two jet aerators, the lower of which is located in the upper chamber of the housing. The reactor itself is made with nozzles for the supply of gases and process fluids, as well as for the removal of the liquid and gas phase. Enrichment of the liquid phase with a mixture of gases is carried out by two-stage aeration using jet gravity aerators with an ejection effect to increase mass exchange processes in a large container. The reactor is equipped with heat exchangers, liquid flow inductors for recirculation of the liquid phase and a pipeline for supplying the liquid phase to the overflow chamber. Liquid phase circulation fittings and liquid phase sampling fittings are installed in the lower part of the housing.
