Abstract (en)
Subject of the invention is a unit generating small gas bubbles in liquid, based on the already known method of the generated bubbles being small if they are exposed, during their formation, to periodic oscillation. In the present embodiment, the aerator generating the bubbles is integrated in a unit with the no-moving-part oscillator. This is a previously unknown layout using the time delay of flow spin-up and spin-down to generate low frequency oscillation which were found to intensify the small bubble generation.
