We propose a magnetic separation system using superconducting bulk magnets to effectively separate organic dyes in wastewater. Two key technologies are applied in this system magnetic seeding and magnetic separation. Magnetic activated carbons (MACs) are used to adsorb organic dyes Orange II and Crystal violet, which serve as magnetic seeds.Sep 01, 1997 In order to run a superconducting magnet in the most energy efficient way means that in order to remove trapped magnetic particles from the matrix area within the magnetic field, the 'trapping' region must be removed from the magnetic field. Carpco has accomplished this through the development of its proprietary reciprocation technology.

High gradient magnetic separation (HGMS) can be a promising new environmental purification technique as it produces no contaminants, such as flocculants, and could possibly treat large amounts of waste water within a short time frame.
