Abstract
The present invention is directed to a system and method for continuously or substantially continuously separating particulate matter based on particle size and/or density of the matter. The system includes a separation chamber having a bottom portion disposed within a cavity of a rotatable bowl having fluid therein, preferably water. The internal cavity of the separation chamber is maintained under negative pressure such that fluid is drawn through the separation chamber at a predetermined velocity to separate the solids. Larger, dewatered and/or denser solids are directed to the cavity of the rotatable bowl and can be removed by rotation of the bowl while the smaller and/or less dense solids and fluid travel up through the separation chamber.
