Abstract: A method and device that comminutes particulate organic substances in suspensions of microorganisms in mediums such as wastewaters or sludges of biological sewage treatment plants, whereby the organic substances are subjected to inertial forces in an active chamber as a result of short-term acceleration, immediately followed by deceleration of a carrier medium flowing in a closed flow channel. To generate these inertial forces, the carrier medium is evaporated and subsequently condensed in the active chamber, whereby this change in the carrier medium's aggregate state is achieved by changing the flow speed. Because of the enormous increase of the liquid phase volume upon its transition into the vapor state, the flow speed of the medium concomitantly increases. As a result, extreme acceleration forces are exerted on the loading of the liquid phase, which immediately after condensation of the vapor into the liquid phase revert back into deceleration forces.

Abstract: A method and device for comminuting particulate organic substances in suspensions of microorganisms in a carrier medium, particularly in wastewaters or sludges of biological sewage treatment plants, whereby the organic substances are subjected to inertial forces in an active chamber as a result of short-term acceleration, immediately followed by deceleration of a carrier medium flowing in a closed flow channel. To generate these inertial forces, the carrier medium is evaporated and subsequently condensed in the active chamber, whereby this change in the aggregate state of the carrier medium is achieved by changing the flow speed. As a consequence of the enormous increase of the volume in the liquid phase upon its transition into the vapor state, the flow speed of the medium increases to the same degree. As a result, extreme acceleration forces are exerted on the loading of the liquid phase, which immediately after condensation of the vapor into the liquid phase revert back into deceleration forces.
