Abstract

Systems and methods for processing waste material are presented. For some embodiments, the system comprises a chamber, an inlet, a fluid outlet, a metal outlet, and a magnet. The inlet is configured to selectively open and close. The inlet injects waste material into the chamber when the inlet is open. The waste material is suspended in a fluid medium, and comprises both ferromagnetic substances and non-ferromagnetic substances. The magnet is a selectively activated magnet coupled to the chamber. The magnet is configured to activate when the inlet is open, and deactivate when the inlet is closed. The magnet attracts the ferromagnetic substances from the waste material when the magnet is activated. The attracted ferromagnetic substances are released from the magnet when the magnet is deactivated. The metal outlet configured to selectively open and close. The metal outlet opens and expels the released ferromagnetic material from the magnet when the magnet is deactivated. The fluid outlet configured to selectively open and close. The fluid outlet opens when the magnet is activated, and expels any remaining waste material after the magnet has substantially attracted the ferromagnetic substances from the waste material.

Claims (9)

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.

2. The method of claim 1 , further comprising the steps of:

opening the inlet, opening the first outlet, and reactivating the magnet; and

resuming the injection of the waste material into the chamber.
