摘要： A system for sludge removal in a circular settling tank having a side wall (106) comprises a rotatable drive ring (130) adapted to be interconnected to a scraper arm provided with scraper blades, wherein the drive ring having a plurality of engagement surfaces (134) A traction assembly (140) is fixedly attached to the side wall and comprises a drive wheel (142). By providing a drive wheel with a plurality of engagement rolls (148) adapted to engage the engagement surfaces of the drive ring during rotation of the drive wheel, the drive ring can be rotated essentially without exerting any radial forces on the drive ring.

摘要： A settling device (1) for liquid treatment including a plurality of inclined, spaced-apart panels (5) each providing an upper settling surface for receiving settled out solid contents of the liquid to be treated, wherein the panels (5) are supported in a box-like structure (2,3,4) including two side walls, and wherein said device includes an inlet or inlets for liquid to be treated and an outlet or outlets for purified liquid. At least one of the side wall sides of the box-like structure (2,3,4) is provided, at the top, with a top portion to be positioned vertically so as to obtain a purified liquid level inside the device between a low level which is below a upper portion of the inclined panels and a high level which is above said upper portion of the panels.

Date Jan. 21, 1993A filtering process for and apparatus separating air bubbles and granular filter medium from a filtrate contaminated by the filter medium and bubbles when passing through a filter bed formed by the filter medium for treatment of a suspension or liquid solution, a gas being passed through the filter medium in contact therewith, includes providing a treated filtrate zone (3) above the filter bed (2), collecting the treated filtrate in the filtrate zone, conducting granular filter medium from the filter bed (2) upwardly through a conveying pipe (4) to a position above the filter bed and thereafter downwardly through a washing apparatus (5) from which the filter medium is precipitated onto a plate (11) above the filter bed. Treated filtrate flows through a separate chamber formed by a cylinder (12) around the washing apparatus (5) and then upwardly through the lower end of the washing apparatus and outwardly through the upper end of the washing apparatus and thereafter leaves the system through an overflow outlet pipe (7). The filtrate leaves the system through a separate filtrate outlet (8). The filtrate flowing downwardly through the separate chamber functions as the washing liquid and flows at a rate sufficiently low for separation of gas bubbles in the chamber therefrom. The filtrate washing liquid flowing upwardly through the washing apparatus (5) flows at a rate sufficiently low for separating the downwardly conducted granular filter medium.

摘要： PCT No. PCT/SE92/00381 Sec. 371 Date Feb. 14, 1995 Sec. 102(e) Date Feb. 14, 1995 PCT Filed Jun. 3, 1992 PCT Pub. No. WO92/21422 PCT Pub. Date Dec. 10, 1992It is possible to filter a suspension or emulsion in a filter bed of particulate filter medium by allowing the suspension to flow upwards through the filter bed simultaneously as the medium flows downwards through a filtering tank wherein filtration takes place. Filtration thus takes place during counterflow between suspension and filter medium. The supply of suspension takes place in the lower part of the filter bed and the filtered liquid phase is taken away from a zone above the filter bed. The polluted filter medium close to the bottom of the filter tank is taken out for conveyance to a washing apparatus above the filter bed and after washing is returned to the upper side of the filter bed. For providing a filter which has a considerably lower construction height for a given and unchanged volume of the filter medium, the washing apparatus is lowered so that its lower part is at a level below the upper surface of the filter bed.
