A device for treating an effluent composed of liquid and of solid particles to obtain a treated effluent includes a filtration device using gravity separation on a rotating cloth having an inlet intended to receive the effluent to be treated and a first and a second outlet, the filtration device being designed to separate the effluent into a first flow and a second flow, the second flow comprising sludges comprising solid particles, the first flow leaving the filtration device through the first outlet, the second flow leaving the filtration device through the second outlet, and at least one recirculation device designed to recirculate at least a part of the sludges of the second flow to the inlet of the filtration device, the second outlet being linked to the at least one recirculation device. A method for treating an effluent is also provided.

A double-action pusher centrifuge separates a mixture into solid cake and liquid. The pusher centrifuge includes a screen drum rotatable about an axis and in which a pusher base device is arranged to be movable along the axis of rotation. The solid cake is displaced by an outer ring region of the pusher base device. A plurality of axial passage openings are disposed in the outer ring region and connect front and rear regions of the screen drum. A feed unit is arranged at an inflow disk such that the mixture can be introduced via the feed unit and the inflow disk into empty space on the screen drum on displacement of the solid cake. An inflow gap applies the mixture into the empty space, and is between an inflow edge of the inflow disk and a pusher base plate of the pusher base device with an inflow region.

Controlled-debris elements inhibit the formation of a fibrous/particulate debris bed that unduly increases the pressure head loss through the perforated plates of strainers in a nuclear power plant emergency core cooling system. In a loss of cooling accident, pumps draw cooling water through the plates, which retain on their surfaces fibrous material in the circulating water to prevent it from reaching the pumps while permitting entrained particulate matter to pass through the perforations. The controlled-debris elements have a specific gravity substantially the same as the circulating water so they are entrained in the cooling water that is drawn toward the strainers and intimately intermix with the fibrous and particulate matter in the cooling water. The elements are configured to provide open structures in the bed formed on the plate surfaces to distribute fibers in the flow away from the surface and maintain cavities between the elements for the particulates.

Systems and methods for separating fluids from drill cuttings. Specifically, the invention relates to shakers that incorporate a vacuum system and methods of operating such systems to effect a high degree of fluid separation. The system and methods are effective across a variety of screen sizes, vacuum flows and vacuum designs.

Embodiments herein relate to part separation and cleaning devices. In an embodiment, a part separation and cleaning apparatus is included having a liquid holding tub defining an interior volume. The liquid holding tub can include a bottom pan defining a center aperture and an outer perimeter, a perimeter wall attached to the bottom pan adjacent to the outer perimeter thereof and a center sleeve attached to the bottom pan over the central aperture and extending upward away from the bottom pan. The apparatus can further include a motor and a drive shaft. An indexing plate within the liquid holding tub can be connected to the drive shaft. The indexing plate can rotate and can include a plurality of discrete compartments. A control circuit can be configured to cause the drive unit to initiate an indexing movement in response to a received signal. Other embodiments are also included herein.

A drum (100) for sorting objects is provided. The drum has a cylindrical shape, and said drum (100) comprises a cylindrical body (101), with an inner and an outer envelope surface. A plurality of pockets (104) are arranged on the inner envelope surface of the cylindrical body (101), and said pockets (104) are provided with openings (105) opening up into the outer envelope surface. At least one groove (106) is arranged on the outer envelope surface, said groove (105) interconnecting at least two openings (105). A machine (1000) comprising such a drum (100) and a method for manufacturing such drum (100) are also provided.

The disclosure provides for thermal, solvent, and/or acid resistant metal organic frameworks and the use of these frameworks in devices and methods for gas separation, gas storage, and catalysis. The disclosure further provides for MOFs that are strong solid acids, and the use of these strong solid acid MOFs in catalytic devices and catalytic methods.
