<p>Within a chamber having an inlet for admitting a sludgy substance for dewatering and an outlet for discharging the dewatered cake of the sludgy substance, there are disposed two laterally opposed filtration trains each consisting of a plurality of rotary filter elements which are each formed of a multiplicity of circular plates arranged face to face in the axial direction at fixed intervals and which are so disposed that they intermesh so as to permit the circular plates of each rotary filter element to partially enter the corresponding spaces between the circular plates of the adjacent rotary filter elements. The two trains of rotary filter elements are disposed opposite each other so that when a sludgy substance is introduced through the inlet and is then caused to advance through the passage intervening between the two opposed trains of rotary filter elements toward the outlet, it is gradually freed from the water component by virtue of the spaces formed in the enmeshed portions of the multiplicity of circular plates of the rotary filter elements arranged as described above, with the result that the dewatered cake of the sludgy substance is concentrated to a gradually higher degree.</p> |
