NOVELTY - Device for electrical disintegration of cell aggregates, comprises: an electrode; a chamber (5) within which the electrode is arranged, exhibiting a wall that is sectionally or completely electrically conductive and is electrically insulated by the electrode, and an inlet (7) for receiving cell aggregates containing fluid; a voltage source for generating electric field by applying an electrical voltage between the electrode and the wall; and a control unit, which interacts with the voltage source for changing the electric field, and changes the voltage between the electrode and the wall.    USE - The device is useful in a disintegration device of a biogas plant or a sewage treatment plant (claimed).    ADVANTAGE - The device: exhibits improved disintegration performance; increases the gas yield in biogas plants; and ensures better utilization of the substrates.    DETAILED DESCRIPTION - Device (1) for electrical disintegration of cell aggregates, comprises: an electrode; a chamber (5) within which the electrode is arranged, exhibiting a wall that is sectionally or completely electrically conductive and is electrically insulated by the electrode, and an inlet (7) for receiving cell aggregates containing fluid; a voltage source for generating electric field by applying an electrical voltage between the electrode and the wall; and a control unit, which interacts with the voltage source for changing the electric field, and changes the voltage between the electrode and the wall. The wall is sectionally electrically insulated such that an inhomogeneous electric field is formed within the chamber. The electrode and/or the wall are partially coated with a dielectric substance. The electrode is a first electrode, and the device comprises a second, preferably a second and a third electrode, which are controllable separately or together by the control unit. The chamber is sectionally or completely formed as a hollow cylinder, and the electrode extends concentrically and/or eccentrically to the cylinder axis of the hollow cylinder within the chamber. The electrode and the wall of the chamber are adapted with each other such that the distance between the electrode and the wall varies in the conveying direction of the fluid containing the cell aggregates. An INDEPENDENT CLAIM is also included for a disintegration device for a biogas plant or a sewage treatment plant, comprising one or several devices for electrical disintegration that are fluidly connected with each other, whose at least one inlet and at least one outlet are respectively connectable with a pipeline for promoting the cell structures containing fluid.
