Abstract
A magnetic separation apparatus is disclosed herein. The apparatus includes a flow-through vessel defining a plenum and an inlet port for introducing fluid into the plenum. A hydrodynamic damping structure is provided between the inlet port and plenum for reducing turbulence in the fluid. A mounting device is provided with a slot therein for supporting and receiving the vessel. The mounting device also supports a first array of magnets along one side of the slot and arranged adjacent one another to face the slot with alternating polarity, and a second array of magnets along the opposite side of the slot from the first array arranged adjacent one another to face the slot with alternating polarity and confronting and magnetically opposing the magnets in the first array. The first and second arrays of magnets produce a magnetic field within the plenum having a field strength that is maximum at a location at the interior surface of a wall of the vessel and that is minimum at a geometrical center of the plenum so that magnetic particles in the fluid are attracted to and immobilized on the inner surface of the vessel.
