Abstract:
1. A method for separating particulate matter from a fluid in which the particulate matter is suspended, the method comprising: feeding a fluid containing particulate matter into a chamber of a vessel through an inlet, the chamber being at least partially bounded by a peripheral wall and the chamber also communicating with a first outlet and a second outlet; rotating the vessel about a rotational axis extending through the vessel such that at least a portion of the particulate matter settles out of the fluid and against at least a portion of the peripheral wall of the vessel; disturbing at least a portion of the particulate matter settled against the peripheral wall so that at least a portion of the particulate matter settled against the peripheral wall is resuspended within the fluid; removing at least a portion of the fluid having the resuspended particulate matter therein from the vessel through the first outlet; and removing through the second outlet of the vessel the fluid from which the particulate material has settled out.
