摘要： Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be formed of a single injection molded piece integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the exterior of the grid frame, which reduces blinding and is resistant to wear and tear.

摘要： A liquid removal apparatus adapted to separate liquid from a composite slurry of liquid and solids. The apparatus includes a movable, permeable membrane having opposing first and second sides. A ‘loaded belt portion’ of the second side is configured to receive the slurry. A permeable membrane support system is configured to provide movable support for the loaded belt portion and includes a transport deck located in contact with the first side of the permeable membrane below the loaded belt portion. The liquid removal apparatus has a housing with a low-pressure chamber in sealing contact with the first side of the permeable membrane. A pressure conditioning system applies a differential pressure via the housing to generate a lower pressure on the first filter belt side than on the second side. The transport deck is located within the low pressure chamber.

摘要： Processing chamber for use with apheresis devices are described herein. An example centrifugal processing chamber includes first and second lateral walls spaced at a distance from one another. Additionally, the example centrifugal processing chamber includes a channel at least partially defined by the first and second lateral walls. Further, the centrifugal processing chamber includes an inlet fluidly coupled to the channel to convey blood to the channel. Further still, the centrifugal processing chamber includes a first outlet fluidly coupled to the channel having a first opening adjacent the first lateral wall. The first outlet is to convey separated plasma from the channel. Additionally, the centrifugal processing chamber includes a second fluid outlet fluidly coupled to the channel having a second opening adjacent the second lateral wall. The second outlet is to convey separated red blood cells from the channel. Additionally, the processing chamber includes a barrier formed along the second lateral wall to intercept platelets. The first and second lateral walls are spaced such that the distance between the first and second lateral walls enables at least one therapeutic unit of single dose platelets to pool adjacent the barrier without spilling into the first outlet or the second outlet.

摘要： A concentrator for removing particulate matter from waste water is disclosed. The concentrator comprises a frame and a high volume compressible filter supported by the frame. The high volume compressible filter is connected to receive the waste water and permit at least some of the waste water to pass therethrough to remove a portion of the particulate from the waste water. The concentrator further comprises at least one compression arm connected to the frame and configured to engage the high volume compressible filter to agitate the waste water within the high volume compressible filter and force waste water from the high volume compressible filter. The concentrator is configured for use with industrial fabrication equipment such as stone and glass processing and water recycling systems.

摘要： A suction head arranged between a filtrate channel and a barometric leg of a rotating filter having at least one filter means communicating with the filtrate channel. The filtrate channel is connected to the barometric leg through the suction head. In order to ensure continuous conveyance of air bubbles brought along the filtrate, the upper internal boundary of the suction head as regards flow towards the barometric leg is nowhere located at a level above the upper internal boundary of the barometric leg.

摘要： Continuously operating filtering devices are voluminous when accommodated in a casing. The casing serves to maintain a determined pressure around the filter, for instance by use of released gases. It is the ojective of the present invention to keep the volume as small as possible. This is achieved by using plastic material for the carrier belt. Up to the present, rubber carrier belts have been used. These however impose limitations on the diameter of the guide rollers. A limitation of the roller diameter to 25% in comparison to rubber carrier belts is possible with the use of plastic. In addition, plastic has a better resistance to aggressive substances.
