A defoaming apparatus ( ) defoams a foamable product that is dispersed into a container such as a TETRA REX gable-top carton ( ). The defoaming apparatus ( ) creates a sonic shock wave ( ) that destroys most if not all of the bubbles of the foamable product. The defoaming apparatus ( ) has a body ( ) that defines a recessed cavity ( ). A pair of electrodes ( ) is located within the recessed cavity ( ). The opening to the cavity ( ) can include a radio frequency filter ( ) covering to absorb radio waves created from the sonic shock wave ( ). The defoaming apparatus ( ) is preferably disposed immediately after the filling of the container ( ).

Defoaming device for a packaging machine

A method is described for the continuous disintegration of microbial sludge in a sewage clarification or sewage treatment plant wherein the microbial sludge is decomposed biologically by bacteria and the resultant sludge (5) is exposed to sonic radiation in a treatment vessel (1) in order to split the cell walls of the microorganisms. With that, the sonic radiation shall be generated asymnetrically in the treatment vessel (1). The intensity of the sonic exposure lies in an area of 500 to 1500 W/m2 and the sludge (5) is fed with a mean dwell-time of 2 to 4 minutes in counter-flow through the treatment vessel (1). The device for carrying out the method possesses a treatment vessel (1) with an eccentrically arranged sonic resonator arranged within (7).
