<p>To separate ink particles from pulp, composed of a wide variety of used paper materials for recycling, the pulp flow (E2,S2;E3,S3) is subjected to at least one current of air bubbles (C). A counter current of water (E1) is in the flow of air bubbles (C) to detach the ink particles, after they have passed through the pulp and carry the ink particles with them. The counter water current detaches the carried particle matter and any fibers, and carries them off in the water flow.</p> |
