Apparatus for magnetic field and magnetic gradient enhanced filtration

摘要

An apparatus (11) for the solid-liquid separation of a solid-liquid mixture containing magnetic particles (15), comprising (a) a tubular filtration region having an axis, wherein the side walls of the tubular region comprise filtration material (12); (b) material (13) that provides magnetic field gradients when placed in a magnetic field wherein the material (13) resides in proximity to the axis of the tubular filtration region along the length thereof; and (c) means to provide a magnetic field.
