When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.
