Abstract: An apparatus for treating waste sludge includes an outer container casing, internally hollow, an inner body coaxial with the outer casing, a compacting and dehydrating chamber, inside the outer container casing and along which sludge to be treated runs, an inlet zone for supplying sludge to the chamber, an outlet zone for unloading treated sludge, movement elements for the sludge, cooperating with the inner body, which promote compaction and advancement of the sludge from the inlet zone to the outlet zone; a container net connected to a negative pole of a control unit to form a cathode, and the inner body connected to a positive pole to form an anode. A method of treating sludge includes the promoting the continuous advancement and compaction of sludge inside a compression chamber between the anode and cathode, and establishing a difference in potential in order to subject the sludge to an electrical field.

Abstract: A device for electrophoresis applies a voltage to a medium in contact with a plurality of electric conductors so that a potential of adjacent conductors is within a certain range. This allows preventing decline in electrophoresis speed. A device for electrophoresis and transfer includes an electrode having a plurality of electrode regions being insulated one another and arranged in a specific direction. This allows providing a practical and easy-to-use device for electrophoresis and transfer. A device for transfer alters an applied voltage or applied voltage duration to a certain position to another position. This allows improving transfer efficiency.

Abstract: Provided is an electro-osmosis dehydrator, which includes a sludge supplying part disposed in a central upper portion thereof, and including a rotating part and two rollers disposed under the rotating part, a drum disposed under the sludge supplying part to receive sludge, and having a cylindrical shape rotating about an axis thereof, wherein an inner circumference of the drum is charged negatively or positively by direct current power, a caterpillar part spaced a certain distance from the drum, and moving along an endless track, wherein the caterpillar part includes a power applying part charged with polarity opposite to that of the drum by direct current power, a filtering fabric disposed under the power applying part, a caterpillar disposed under the filtering fabric, and including a plurality of holes, a vinyl part disposed between the filtering fabric and the caterpillar to prevent the sludge from passing through the caterpillar, and a chain disposed under the caterpillar, and a plurality of idle sprocke

Abstract: The scope of the invention is to apply an electric current or to use a kind of iontophoresis system with the hemodialysis cartridge and system (the proposed method is also applicable to peritoneal dialysis or other similar methods) to remove unwanted molecules from blood, plasma or serum or other body fluids and to increase the effectiveness of the process. This cartridge can be used for patients with uremia and cartridge fixed to the conventional hemodialysis machine and additionally the electric current applied to the electrodes placed in to the cartridge or electrode connectors placed to the conventional cartridge. When the system activated, the molecules in the blood or other body fluid migrates to the hemodialysis solution. Charged ions or uncharged molecules move together with electroosmotic flow. The sterilized electrodes preferably made by Ag/AgCl to prevent pH changing effect. Other apparatus can also be used for providing an electropotential gradient.
