Abstract
An apparatus for filtering suspensions is provided with rotatable annular vertical disks (4) covered with filter material and partly submerged in the suspension to be filtered. Each disc is provided with a number of cells (22) for receiving filtrate from the suspension as the disc is rotated. The cells of each disc communicate with a central filtrate chamber (7) via respective accumulation chambers (30) formed by wall means (31) in the filtrate chamber. Each accumulation chamber of each disc extends axially past the disc and has an outlet (32) which also extends axially past the disc. The advantage is that a more concentrated coarse fraction of the suspension can be achieved.
