Abstract
Embodiments of the present disclosure include separating devices and systems and methods of use. Embodiments of the present disclosure include separation devices including magnetic arrays and sheet-flow separation chambers. In an embodiment, the separating device enables the generation of multiple, and in some configurations, intersecting, high gradient magnetic field lines, resulting in strong separation forces, which permit for scale up to large areas and/or volumes (e.g., extracorporeal blood filtration system).
Claims13
A separation device, consisting of:
- a magnetic array, and a horizontal sheet-flow separation chamber having only one entrance opening and only one exit opening, wherein the sheet-flow separation chamber is configured so that magnetic particles suspended in a fluid are continuously separated as the fluid flows across the sheet-flow separation chamber from the entrance opening to the exit opening, wherein dimensions of the fluid flow in plane are at least three times the depth of the fluid perpendicular to the plane, wherein the magnetic array is an electromagnet;
- and wherein the electromagnet comprises conducting coil loops and solenoids, magnetic coils, or combinations thereof, wherein the sheet-flow separation chamber is disposed under the magnetic array.
A separation device, consisting of:
- a magnetic array, and
- a sheet-flow separation chamber consisting of one entrance opening and consisting of one exit opening, wherein the sheet-flow separation chamber is configured so that magnetic particles suspended in a fluid are continuously separated as the fluid flows across the horizontal plane of the sheet-flow separation chamber from the entrance opening to the exit opening, wherein dimensions of the fluid flow in plane are at least three times the depth of the fluid perpendicular to the plane,
- wherein the magnetic array is an electromagnet;
- and wherein the electromagnet comprises conducting coil loops and solenoids, magnetic coils, or combinations thereof,
- wherein the sheet-flow separation chamber is disposed on a side of the magnet array.
