The injection of gas into H2O, through a hollow needle gives a stream of bubbles. These bubbles can be effectively broken up by application of high-voltage pulses. This mechanism works in demineralized H2O and even in conducting tap H2O if the pulses have a short rise time. Bubble diams. down to at least 50 mm can be obtained. The pulse source uses either a high-voltage tetrode or a spark gap as switching element. Extremely small bubbles are produced at a high rate and a low power input. Applications of this method can be found in the chem. process technol. [on SciFinder (R)]
