  • Publication number: 20120055797
    Abstract: It is an object of the present invention to provide an improved method of electro-dewatering substances by increasing the efficiency with which water is removed from the substances, thus permitting substances to attain higher dryness levels with the same energy input and surface area, or to attain similar dryness levels with less energy input or less surface area.

  • Patent number: 7828953
    Abstract: The present invention relates to a process for treating sludge by the combined action of electro-osmosis and pressure. This process comprises providing a cell for treating the sludge, the cell comprising at least two electrodes including at least one cathode and at least one anode. At least one of the electrodes is movable, and at least one of the electrodes is perforated so as to drain effluents. Then, the sludge is introduced into the cell between the at least two electrodes, each of the electrodes defining a surface adapted to constantly contact the sludge. Then, the sludge is submitted to an electric current by applying a voltage to the electrodes, and applying a pressure to the sludge by means of the at least one movable electrode so as to permit a constant contact between the surfaces and the sludge. An apparatus for carrying out such a process is also disclosed.

  • Publication number: 20100129559
    Abstract: There is provided a system for spreading a substance. The system comprises a at least two rotating means disposed in a housing. The rotating means are adapted to compress and move said substance. The system permits to control the thickness of the substance to be spread through the outlet. Methods for spreading a substance are also provided.

  • Publication number: 20100086437
    Abstract: There is provided a process for at least partially deactivating microorganisms in a solid material. The process comprising submitting the solid material to an electric current having a voltage gradient of at least 3 volts per centimeter of solid material to be treated, and a current density of at least 2 mA per cm2 with respect to the surface of electrodes used for generating the current.

  • Patent number: 7578918
    Abstract: 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 evacuating 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 electrodes 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 sludge in order to dehydrate and decontaminate the sludge.
