Abstract: A frame-type disc filter (100) is provided with a bypass water collector (33) disposed adjacent an inlet to the disc filter. Influent water overflows the inlet into the bypass water collector. A conduit is communicatively connected to the bypass water collector for directing the bypass water from the frame-type disc filter to an effluent channel that is independent of the frame-type disc filter.

Abstract: A rotary filter has a pressure vessel and a rotor from which a plurality of filter cells are suspended from outer portions of the rotor so that they clear a conveyor located proximal to the axis of rotation and upon which the filter cake is removed. Conduits are connected to the filter cells from a single distribution head for initially evacuating the cells in the filter stage and thereafter pressurizing the cells to dislodge the filter cake while the vessel remains under pressure. The filter cells can have the filter surfaces extending generally in axial planes or in axially spaced relationship in planes wherein a plurality of angularly spaced filters extend generally radially from respective filtrate conduits running axially along the outer part of the rotor.

Abstract: A method and apparatus for fibrous suspensions in the wood processing industry and more specifically to a so-called drum cylinder, the basic construction of which comprises a vessel, into which suspension being thickened is supplied and a wire-surface cylinder rotating in the vessel. The drum filter is characterized in that the closure member of the drum filter has a channel for leading gas from the filtrate tubes through the compartments of the distribution chamber to the outside of the closing member. The method is characterized in that the operation phase of the filter cylinder is divided into five separate stages. In the first stage, when the cylinder descends on to the vessel, air and the initial filtrate are discharged from the filtrate components and the formation of the pulp web on the wire surface begins. In the second stage, filtrate is discharged with vacuum and the formation of the pulp web continues. In the third stage, pulp web is dried by means of vacuum when said part of the web has risen with the cylinder from the vessel. In the fourth stage, a so-called removal stage, the pulp web is removed from the wire surface and discharged from the apparatus. In the fifth stage, a so-called washing stage, the wire surface is washed.

Abstract: A filter for continuous filtering of suspension under pressure includes a pressure vessel, a shaft rotatably journalled in the pressure vessell and disc filters elements arranged on the shaft. The filter elements are composed of sectors and inlet filtrate channels in each sector are connected to axially extending channels in the shaft, one axial channel for each sector. The axial channels are connected to a filtrate valve formed to divide the filtering cycle corresponding to one rotation revolution for the filter elements in a number of filtering zones, at least one in liquid phase and one in gaseous phase. A separate filtrate outlet from the pressure vessel is connected to each filtering zone and means is controlling the difference pressure over the filtering zones independent of each other.

Abstract: 1,036,457. Rotary drum filters and sheet filters, for liquids. H. B. FEHLMANN. Sept. 24, 1963 [July 31, 1963], No. 37458/63. Heading B1D. Sludge is introduced from a I-section tank 3, 4, 5, Fig. 2, past slide valves 41, 40, Fig. 1, to the interior of a drum 14, where the residue forms a sludge roll 56 which is kept rotating on the filter cloth lining 28 by the rotation of the drum. The outer end of the roll is continuously cut away and discharged by an edge 35. Vacuum is applied to a sectionalized base structure 19, 20, by a fan 12 and pipe 11, collected water being drained from the drum hub by a pipe 53 immersed at 50. On Fig. 5 an annulus of filtering material 81 is fixed at its edges 63, 64, and is formed into a series of radial crests and troughs by an annular tray-shaped supporting structure 75, so that one set of troughs (e.g. 90) communicates with a circular feed gutter 82 while the troughs (e.g. 91) alternating therewith do not. A crest is formed between every two troughs. The structure 75 is rotated by a motor 73 and a cylinder 72 so that eventually sludge rolls 92 form and rotate in the troughs 91. The inner end of each sludge roll is continuously cut away and discharged by an edge 87.
