Filtration device and filtration system

A filtration device comprising:

• a closed container having a closed space;
• a filter chamber to which a slurry containing particles and a liquid having different electric charges is supplied through a supply line;
• a first electrode group and a second electrode group, provided on both side surfaces of the filter chamber to face each other, the first electrode group including at least a first cathode electrode and a second cathode electrode configured to separate the particles and the liquid in the slurry into separated substances by a cathode electric field action generated between the first cathode electrode and the second cathode electrode, the second electrode group including at least a first anode electrode and a second anode electrode configured to separate the particles and the liquid in the slurry into separated substances by an anode electric field action generated between the first anode electrode and the second anode electrode;
• a plurality of power supplies;
• and
• a first discharge chamber and a second discharge chamber being configured to allow discharging of the separated substances,
• wherein:
• the first cathode electrode and the second cathode electrode are interposed between the filter chamber and the first discharge chamber, the first cathode electrode and the second cathode electrode comprising holes that allow the filter chamber to communicate with the first discharge chamber;
• the first anode electrode and the second anode electrode are interposed between the filter chamber and the second discharge chamber, the first anode electrode and the second anode electrode comprising holes that allow the filter chamber to communicate with the second discharge chamber;
• a number of the plurality of power supplies is the same as a number of electrodes contained in the first electrode group and the second electrode group, each electrode of the electrodes being connected to one power supply of the plurality of power supplies;
• and
• the first electrode group and the second electrode group extend across an entirety of the filter chamber to divide the closed space.
