Abstract:
This separation method comprises a supply step (S2) for supplying bubbles, which include at least either nanobubbles or microbubbles, to a mixture that contains a water absorbent polymer and pulp. This separation method comprises a recovery step (S5) for recovering the water absorbent polymer, which has been separated in a mixed liquid that contains the water absorbent polymer and the pulp, since the water absorbent polymer to which bubbles are adhering floats, while pulp settles out in the mixed liquid.
