Fundamental Study of Magnetic Separation of Emulsion using a Superconducting Bulk Magnet

Abstract

To separate oil contents from industrial and domestic wastewater with for the purpose of water purification and recyclying, magnetic separation of simulated emulsion wastewater was performed. Magnetic separation technology is roughly divided into magnetic seeding and magnetic separation. First, we confirmed the possibility of magnetically seeding emulsion using a flocculation method with polymer additives. For practical separation, we performed a separation experiment and particle trajectory simulation in a model system using a bulk superconducting magnet. From the results, we examined the basic conditions for highly effective magnetic separation of emulsions.
