In the article the main processes of hydrodynamic regime of aeration tank are observed: the formation and ascent of air bubbles during aeration and motion of the water-sludge mixture. The formulas for determining the potential speed of an air bubble during aeration and energy of the water-sludge stream motion are presented. The investigation of interaction mechanism of purified waste water and air bubbles in the process of aeration in relation to the flow dynamics is poorly explored and challenging. Interaction of energetic components of the bubbles flow during aeration and uniform stream motion in the aerotank is the part of mass transfer and diffusion. The increase in total energy of the system by means of summing and raising potentials of the stream and bubbles speed can lead to increasing the purification effect, that means speeding up the diffusion processes.
