    摘要： A stormwater treatment device includes a tank defining an internal volume and having an inlet and an outlet, a rotatable screen unit mounted within the tank, the rotatable screen unit being barrel-shaped to define a through path with an inlet end and an outlet end. The rotatable screen unit includes a screen structure with a plurality of screening openings for allowing passage of at least some water from the through path outwardly through the screen structure while inhibiting passage of trash items through the screen structure such that trash items move along the through path from the inlet end to the outlet end. The rotatable screen unit includes a plurality of external drive paddles that rotate with the screen structure and that interact with water that has been screened by passing outwardly through the screen structure interacts with the external drive paddles to cause rotation of the rotatable screen unit.

    摘要： The present invention relates to a filtering panel (100) for a disk filter and a disk filter for water purification, comprising a metal filter cloth (16, 116) such as a stainless steel filter cloth, pre-tensioned in both warp and weft directions and fastened to a frame (10, 110) comprising a peripheral portion (11, 111), which is integral with an inner grillwork (12) and which divides the inner area of the peripheral portion (11, 111) into fields (15, 115). The frame (10, 110) comprises a plastic material reinforced with glass fibers or carbon fibres such as polypropylene loaded with fibreglass in an amount of at least 20 weight percent. Each field of the grillwork (12, 112) has an area not exceeding 10% of the inner area of the peripheral portion (11, 111). The pre-tensioning of the filter cloth (16, 116) in both directions is from at least 20% of the yield stress of the cloth (16, 116). Further the present invention relates to a disk filter comprising said filtering panels (100) and method of making said filtering panel (100).

    摘要： A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a housing for rotatably supporting a removable screened drum on a plurality of rollers. The drum receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube disposed within the drum is configured to direct air through the screens to an air blower intake positioned outside of the drum.
