  • Method for deinking recycled fiber by applying direct current electric field
    Patent number: 5238538
    Abstract: A method for the deinking of recycled fibers, in which the macerated fibers are slurried with water; introduced to a deinking cell which has a central anode and a perimetal cathode; subjected to a direct current electric field applied between the anode and the cathode, causing the ink to be attracted away from the fibers and to electrocoagulate the ink then floating to the surface of the slurry with the aid of gas bubbles generated during the application of the electric field; and washed to recover a cleaner, brighter pulp of recycled fibers.
