    摘要： A rotary drum type device (1) for separating solid particles from a liquid includes a rotary screen drum (2) having support rods (4) extending in the axial direction and arranged cylindrically and having a projecting portion in a radially outward end portion, and a wedge wire (5) wound spirally on the outer periphery of the support rods (4) in substantially crossing direction to the support rods (4). The wedge wire (5) is arranged with its one side facing outward and two other sides forming a slit which widens radially inwardly between adjacent wedge wire portions and with an inward apex of said wedge wire being welded to the projecting portion of the support rods at crossing points. The rotary drum type device further includes a container (8) containing a liquid to be treated disposed outside of the rotary screen drum (2) for reducing pressure in the rotary screen drum (2), and a scraper (12) for stripping off cake produced on the outer periphery of the rotary screen drum. The width of the slit of the wedge wire (5) is within a range between 1 micron and 150 microns.

    摘要： A sludge dehydrating press (1) includes an outer screen case (2) in which sludge to be treated is filled, the outer screen case having a screen surface in at least a part thereof, press means (3) for pressing sludge filled in the outer screen case (2), one or more inner screen cases (4) disposed slidably in said outer screen case (2) including a screen surface extending in a directon crossing the direction of pressing by the press means (3) and having continuous slits and the inner screen cases (4) having also a space into which water extracted from the sludge flows, and positioning means (26) for positioning the inner screen cases (4) to a predetermined position after completion of pressing by the press means (3). The screen surface of the outer screen case (2) preferably is made of a wedge wire screen having a flat inside surface
