| 摘要 |
An apparatus comprising at least vessel (2) for stocking conductive liquid (1) containing impurities; electromagnetic force generator (3) for generating electromagnetic force (F) capable of circulating the conductive liquid (1) in the conductive liquid (1); and discharging unit (4) for discharging nonmetallic impurities and deemed nonmetallic impurities (21a,21b) accumulated in low-pressure region (1a) by a pressure difference in conductive liquid (1) induced by the electromagnetic force (F), so that by the electromagnetic force (F), any nonmetallic impurities (21a) and deemed nonmetallic impurities (21b) are driven to the low-pressure region (1a), for example, liquid surface and separated.
