A fluid cleaning system for cleaning contaminated water sources via at least one cleaning process. The system includes at least one solids dissociation apparatus that includes a housing, at least one insert operably engaged with the housing and is adapted to receive a continuous fluid stream, and a transducer operably engaged with the housing and is disposed about the at least one insert at a distance away from said at least one insert inside of the housing. The transducer is configured to create cavitation, via sonic waves, to eviscerate contaminants in the continuous fluid stream. The system also includes at least one solids separation apparatus operably connected with the at least one fluid treatment apparatus for receiving the eviscerated contaminants provided in the fluid stream. The at least one solids separation apparatus is adapted to separate the eviscerate contaminants from the fluid stream for at least one separation process.

Provided is a method that, when pulp fibers are recovered from used absorbent articles that have been put into collection bags, makes it possible to safely and sanitarily crush the used absorbent articles while suppressing costs. A method for recovering pulp fibers from used absorbent articles, the method comprising: a crushing step (S12) in which collection bags (A) in which used absorbent articles have been sealed are put into a container (65), the collection bags in the container are transferred to a crushing device (12) that communicates with the container, and, bag by bag, the crushing device crushes the used absorbent articles in the collections bags in a deactivating aqueous solution; and a separation step (S13) in which the pulp fibers, a highly water-absorbent polymer, and the deactivating aqueous solution are separated from the crushed product and deactivating aqueous solution obtained in the crushing step.

A device for granulating sludge has a hollow-cylindrical die into which sludge to be granulated is to be injected and in which a stripper with at least one knife is rotatingly arranged. A knife holder holds at least one knife radially movably on the rotating stripper.

A method for fragmenting and/or weakening pourable material with high-voltage discharges includes guiding an annular or arcuate material flow past a high-voltage electrode assembly while immersed in a process liquid, by means of which high-voltage electrode assembly high-voltage punctures through the material flow are produced in that high-voltage pulses are applied to the high-voltage electrodes of the high-voltage electrode assembly by means of a high-voltage generator. Material is fed to the flow upstream of the high-voltage electrode assembly, and material is led away from the flow downstream of the high-voltage electrode assembly. This enables a continuous process, in which the speed of the material and the intensity of the high-voltage punctures can be set in wide ranges, and any insufficiently processed material can be fed back to the process zone over a short distance and practically without additional space requirement.

A size reduction device and method for solid particles, which are conveyed as a suspension in a liquid flow. The device includes a housing, at least two counter-rotatable size reduction components disposed in the housing, each including a plurality of cutting elements, disposed on a common rotatable shaft with a longitudinal axis. The flow direction of the suspension is at right angles to the longitudinal axes of the shafts of the size reduction components. Two mutually opposite guide rails with a longitudinal axis parallel to the shafts are assigned to components. Each guide rail includes a base plate, on which ribs with channels are constituted parallel to the flow direction on the side of the base plate towards the component.
