An apparatus for treating slurries, in particular biogenic or industrial slurries, can include at least one treatment rotor which is arranged or can be arranged in the slurry and which rotates or is rotatable about an axis of rotation (R), with treatment elements which project outward, as seen from the axis of rotation (R), and between which interspaces are formed, at least some of the treatment elements having, atat least one, preferably eachadjacent interspace, in each case at least one treatment edge, preferably at least two treatment edges spaced apart from one another, each of these treatment edges running from the inside outward, as seen from the axis of rotation. Methods for treating slurries are also disclosed, including methods using the apparatus for treating slurries.

An apparatus for recovering the suspended particles from waste water comprising a tank (10) having an upper section (14) for receiving waste water, a lower chamber (16) and a base plate (18) separating the upper section (14) and the lower chamber (18). In one aspect the base plate is a filter screen that has a central opening (20) and a closure 28 therefore. The apparatus has a filter press plate (24) within the upper section (14) and is moveable between a non-filtering position spaced away from the base plate (18) and a filtering position in which the filter member (24) and base plate (18) are pressed together so as to separate water from the particles and compress the particles to form a substantially dewatered product that can then pass through the opening (20) into the lower chamber (16) for collection.
