PCT No. PCT/JP97/00797 Sec. 371 Date Oct. 6, 1998 Sec. 102(e) Date Oct. 6, 1998 PCT Filed Mar. 13, 1997 PCT Pub. No. WO97/33696 PCT Pub. Date Sep. 18, 1997A U-shaped side of a yoke is mounted on the confronting sides of two rotating plates attached to the inside of a magnetically agglomerating and treating tank, and a plurality of magnets, each having a magnetic force of not less than 12,000 gausses, are mounted on the confronting sides of the yoke, respectively, and the gap between the faces of the confronting magnets is set at 300 mm to form a magnetic field. Liquid containing impurities, such as magnetic and non-magnetic suspensions is caused to flow into this magnetic field for contact with the magnets for a predetermined period of time, so that the non-magnetic suspension is magnetically agglomerated together with the magnetic suspension, so as to be attracted to the magnets, and the magnetically agglomerated matter adhering to the surfaces of the magnets is separated. |
