ELODE is based upon a new technology that allows for highly efficient dehydration by isolating moisture from sludge using the mechanisms of electrophoresis and electro-osmosis. Distinguished from conventional dehydrators using pressure-applied dehydration technology, ELODE supplies the sludge cake that has been dehydrated for the first time in between the anode drum and the cathode caterpillar. Then, the three-phase AC voltage is applied between the two electrodes, strongly pushing the various cells of sludge toward the cathode. Dehydration of high efficiency with a moisture level below 60wt% is accomplished accordingly.

Electro-Osmosis Process of ELODE®


  1. Early Electro-Osmosis: Negatively charged (-) sludge particles to the anode in electrophoresis.

  2. Intermediary Electro-Osmosis: Moisture isolated by electro-osmosis dehydrates through the cathode.

  3. Final Electro-Osmosis : Bonded moisture of sludge is forced by the capillary pressure to move to the cathode.

  4. Cell Membrane Destruction: Destruction of cell membranes discharges the bonded moisture of sludge.
