Abstract
Synopsis: In Korea superconducting HGMS has been applied for the treatment of various kinds of wastewater. The wastewater from paper factory was successfully purified by HTS superconducting magnet system after pre-treated with magnetite and coagulant. For the treatment of coolant of hot rolling process in iron manufactory, coagulation conditions were investigated. Three different types of magnetic separation systems were applied and the suspended solids in the coolant were effectively removed. The treatment of condenser water in thermal power plant which mainly consisted of iron oxides was studied by investigating the effect of magnetic field strength, magnetic filter wire size, and filter composition on the turbidity decrease. Recycling of abrasives from waste slurry by magnetic separation was also investigated. The studies demonstrated that superconducting HGMS is feasible to apply to various kinds of wastewater and suggested improvements for better performance of HGMS system.
