The main sources of acoustic fluctuations are radiators on a basis piezoelectric ceramics. Pyezokeramichesky radiators usually work at powers up to 1 kW. A food of these radiators is carried out from ultrasonic generators which can work in two modes: key and linear. To condition of optimization of a consistent chain when performing the specified criteria, namely the minimum weight, stability of coefficient of transfer of the main harmonica at change of resistance of loading and the maximum power factor the scheme, with implicit longitudinal and cross compensation satisfies. Amplitude modulation is applied to increase of efficiency of ultrasonic impact on sewage. Operation of the ultrasonic converter on water in a continuous mode leads to that about its radiating surface at low frequencies the shielding area which consists of a set of pulsing and cavitational bubbles is formed.
