The object of the invention is an apparatus (50) for magnetic treatment of fluids, comprising a substantially cylindrical housing (6), having a bottom wall (61), a top wall (62), and a sidewall (60) running around the circumference of the bottom wall (61) and of the top wall (62) of the housing; at least one inlet opening (2, 3) and at least one outlet opening (4) formed in a wall of the housing (6); at least one magnet (8) connected to the housing (6), wherein the magnetic field of the magnet intrudes into the housing; wherein one or more inlet tubes (30) are connected to the one or more inlet openings (2, 3), wherein the inlet tubes are at least partially tangential at least in the proximity of the inlet opening. As a result of this configuration, the velocity vector of the fluid to be treated has a significant tangential component during most of its travel through the apparatus and thus the fluid crosses the magnetic field lines of the magnets having their magnetic axes oriented parallel with the centerline of the housing such that the angle formed between said field lines and said velocity vector is large.

A magnetic drum separator comprises a drum rotatable about an axis, the drum comprising an internal chamber and an opening at an end of the drum providing access into the internal chamber. The magnetic drum separator also comprises an inlet for supplying a liquid or granular substance into the internal chamber through the opening, a magnet outside of the drum for attracting magnetic material in the liquid or granular substance towards an internal sidewall of the internal chamber, a collection device for recovering magnetic material attracted to the internal sidewall and an annular seal member attached to the end of the drum that rotates with the drum in use. A baffle that bears against the annular seal member partially seals the opening. A plurality of cavities formed in the annular seal member receive fluid leaking into a boundary between the annular seal member and the baffle.
