PROCESS AND APPARATUS FOR TREATING SLUDGE

摘要

The present invention relates to an apparatus for treating sludge comprising electrodes including at least one anode and at least one cathode. The electrodes define therebetween a space adapted to receive the sludge so as to submit the sludge disposed within the space to an electric current, thereby dehydrating the sludge and generating an effluent. The apparatus also comprises an inlet for receiving the sludge and an outlet for evacuatin g the treated sludge. The inlet and the outlet are in communication with the space. The apparatus also comprises compression means for compacting the sludge so as to permit a contact substantially constant between the electrod es and the sludge when the sludge is submitted to the electric current and rotated around a rotation axis. The invention also relates to a process for treating sludge, The invention is useful for treating various types of sludg e in order to dehydrate and decontaminate the sludge.
