SELECTIVE SEPARATIONS IN ENVIRONMENTAL AND INDUSTRIAL-PROCESSES USINGMAGNETIC CARRIER TECHNOLOGY

The use of magnetoprocessing techniques in conjunction with magnetic s upports for selective separations of colloidal particles, macromolecul es and organics, on a industrial scale is reviewed. A specific case is presented illustrating liquid phase mass transfer enhancements attain able using a novel magnetoprocessing technique, the magnetically stabi lised fluidised bed reactor (MSFBR). Results showed that a more than f ive-fold increases in liquid throughput could be achieved when a curre nt of 40A was applied to a bed of magnetite/carrageenan gel beads. The paper emphasises potential magnetoprocessing applications for selecti ve separations in mineral, biological and effluent treatment processes .
