Abstract

The device has a truncated cone shaped filtering wall (14) opened towards top, and a transporting conduit (41) for treating a slurry (42) at a top part of the wall. A rotational sprinkling head carries four nozzles aligned parallel to a surface of the wall. The nozzles respectively project plane water jets (26-29) towards the wall, where the nozzles produce the jets (27, 28) respectively having two marks that are spaced with respect to each other. The wall forms an angle of 20 degree with respect to a normal plane at a rotation axis (AX) of the wall.
