Abstract:
1. A method comprising the steps of: injecting waste material into a chamber through an inlet at a predefined rate, the waste material being suspended in a fluid medium, the waste material comprising ferromagnetic substances, the waste material further comprising non-ferromagnetic substances; activating a magnet when the waste material is being injected into the chamber, the activated magnet substantially attracting the ferromagnetic substances that are suspended in the fluid medium, the attraction of the ferromagnetic substances resulting in a remaining waste material; expelling the remaining waste material through a first outlet; closing the inlet, closing the first outlet, and deactivating the magnet, the deactivating of the magnet resulting in a release of the attracted ferromagnetic substances; and expelling the released ferromagnetic substances from the chamber through a second outlet.
