Abstract: Anapparatus for continuously filtering a sludge suspension, having a hollow shaft (2) that is rotatably mounted in a housing (1) and which that is fluidically connected to an inner chamber (6), which is surrounded by a filter membrane (5), of a discoid filter element (3) that radially protrudes from the hollow shaft (2), for removing a filtrate. A higher throughput of the filtrate, independently of the solids content of the sludge suspension to be filtered, is provided by the filter cake thickness and the filtration duration. The the radius (r) of the filter element (3) increases in the circumferential direction from a low pressure radius ri to a high pressure radius rh,reducing the free housing cross section.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter inlet and a filter outlet are positioned along a bottom portion of the filter housing, and filter media is positioned within the filter chamber to remove contaminants from water flowing through the filter media. A divider wall is positioned within the filter chamber to direct the flow of water through a flow aperture at a top portion of the filter chamber, such that the filter chamber remains filled with water during operation. As a result, the filter media remains completely submerged, thereby improving filtration performance, reducing pressure drop, and more evenly depleting the filter media.

Abstract: A filtering device includes a pleated filter that includes a filter base having folds that repeatedly form mountains and valleys and having a cylindrical shape whose direction of an axis is a ridge line direction of the folds and in which the mountains are located outward in a radial direction, an untreated-water nozzle through which untreated water is ejected toward an outer circumferential surface of the pleated filter, a case that includes an outer tubular portion provided so as to surround the pleated filter and including a nozzle opening of the untreated-water nozzle therein, a filtered-water flow path that leads filtered water having passed through the pleated filter from the inside of the cylinder of the pleated filter to the outside of the case, and a discharge flow path through which discharge water that is not filtered by the pleated filter is discharged to the outside of the case. The pleated filter is configured to rotate in a direction about the axis. Ridge lines of the plural mountains of the pleated filter are curved in a shape that expands in a direction opposite to the rotation direction.

Abstract: A single roll wash press comprising a housing and a drum rotatably mounted within the housing. The drum includes a perforated outer wall and a longitudinally extending centerline axis and is rotatable about the axis. The press further comprises a means for receiving a flow of pulp having an initial consistency ranging from about 2% o.d. to about 6% o.d. such that the pulp flows in the direction of drum rotation, and a means for defining a divergent formation zone and for forming a mat of the pulp on the drum within the divergent formation zone. The means for defining and forming comprises a first arcuate portion of the housing with the formation zone being divergent between upstream and downstream ends thereof. The upstream end of the divergent formation zone communicates with the means for receiving the flow of the pulp. The press further includes a means for washing the pulp mat within a displacement zone disposed downstream of the extraction zone. The press may further include a means for increasing the consistency of the pulp within an extraction zone disposed circumferentially between the formation and displacement zones.
