Abstract: A method and an apparatus for washing a solids-containing suspension by means of a suction drum washer comprising a drum provided with a filtration surface, a main vacuum source such as a drop leg and washing tubes connected to the frame of the suction drum washer. A washing liquid stream is introduced by a first washing tube is directed to contact the pulp layer on the surface of the drum in a point below 10 degrees after the surface of the suspension and a vacuum of at least 0.1 bar greater than the main vacuum source, i.e. intensified suction is applied by means of a separate vacuum source to filtering surface at the contacting point of the first liquid stream and the pulp layer or maximum of 10 degrees before the contacting point. The intensified suction may be utilized also for boosting end of filtration stage (II) and drying stage (IV). Filtrate from the drying stage (IV) can be used at the same washer as a washing liquid at the first or the second washing tube.

Abstract: The invention relates to a filter assembly for producing a paste-like filter cake and a substantially solids free filtrate or permeate. The filter assembly includes a substantially cylindrical member having an exterior foraminous surface, the cylindrical member being mounted on an elongate shaft for rotating the surface about an axis defined by the shaft. The exterior foraminous surface is covered by a microporous filter media. A stationary housing is positioned adjacent a portion of the exterior surface of the cylindrical member. The stationary housing includes a filter feed inlet and a sealing device and is spaced from the exterior surface a distance sufficient to enable cross flow relative to the filter media. Unique filter seal members promote retention of fluid to be filtered in a filtration area defined by the housing and cylindrical member. As the cylindrical member is rotated about the axis, a cake removal or membrane cleaning device removes filter cake from the filter media. The unique filter seal members enable use of a rotating cylindrical member containing the filter media. The unique design of the filtration device provides high solids production similar to a drum or belt filter without the use of filter aids and provides fine particle removal from a liquid similar to a membrane filter, however with substantially higher solids content than with a conventional membrane filter.

Abstract: A rotary drum filter arrangement in which an endless flexible filter belt is trained around at least 270.degree. of the vacuum drum and leaves the vacuum drum for application of a slurry and formation of a cake remote from the drum. In one form of the invention the slurry is applied to a substantially horizontal portion of the belt prior to entry onto the vacuum drum so gravity aids in initial dewatering. In another form of the invention the cake is formed by an auxiliary vacuum drum prior to entry onto the main vacuum drum. By utilizing at least 270.degree. of the vacuum drum after formation of the cake, the invention provides a drier cake, easier adaptation of auxiliary washing and drying equipment and/or permits the use of a smaller vacuum drum.

Abstract: A rotary drum filter comprising a generally annular rotatably driven drum having filtrate compartments which extend generally longitudinally along the drum outer circumference. The filtrate compartments are overlaid by cover elements which have filtrate passages on their outer peripheries inwardly of a foraminous filter medium; and the filtrate passages are communicated with the filtrate compartments by drainage openings in an edge portion of each cover element at intervals along the length of the drum. The drainage openings are constructed to discharge filtrate to their respective communicating filtrate compartments in a direction at least generally towards the discharge ends of the latter whereby the discharging filtrate has a substantial velocity component in such direction.
