The parameters of the mixers widely used in the practice of water treatment are given. A fundamentally new design of the mixing unit is proposed, which provides a process of rapid and complete mixing of reagents in a thin layer of a rotating flow of a pre-created water-air mixture using the method of concentrated coagulation. At the same time dispersion of air bubbles is carried out. A detailed description of the design, operating principle and basic design parameters of the mixer used in the mixing unit.
