Apparatus for the purification of liquids, and in particular of water, by means of the technique of high-gradient magnetic separation, which apparatus is constituted by a central-shaped-core magnet, whose core (20) is so shaped as to create an air gap (22) to the passage of a magnetic flux (F1) in a direction substantially perpendicular to the surfaces of the poles, with a prismatic tray-shaped (27) basket being positioned inside said entrefer, inside which basket a filter (28) is installed, which is constituted by a material with a high value of magnetic permeability, and preferably is steel, in such a physical shape as to accomplish the conditions for a high-gradient magnetic field to be obtained, with said material being, i.e., in the form of loosen fibres or wires, or in the form of net-like cloths, or in the form of suitably supported powders, or the like. |
