Abstract
Disclosed is a process and apparatus for treatment of liquid. Liquid is introduced into a reaction vessel (10) and rises inside a first chamber (12) of the reaction vessel (10). The liquid is led out of the first chamber (12) downwardly along an outer surface (40) of the first chamber (12) in a thin film into a second chamber (14). In a third chamber (16) energy for raising the internal energy of the liquid is supplied to the liquid by means of an energy supply device (30). The treated liquid is withdrawn from the reaction vessel (10). The energy supply device includes an ultrasound-emitting transducer in which a piezoceramic disc (82) is supported via an elastic seal (84) between a pot-shaped housing member (78) and a sleeve (80).
