  • Patent number: 7465391
    Abstract: An apparatus for separating solid matter from a liquid stream, where the apparatus includes a generally cylindrical separation panel surrounding an interior space, which is oriented so as to have a substantially vertical longitudinal axis. The separation panel has a plurality of vertically and horizontally spaced openings which are adapted to remove solid material larger than a predetermined size from liquid passing through the separation panel. The apparatus also includes a chamber surrounding the separation panel and providing a chamber portion into which the liquid passes after passing through the separation panel. The apparatus may further include an inlet positioned below the separation panel, through which the liquid stream is delivered from a bottom opening of the separation panel to the interior space and which is arranged such that the liquid circulates about the axis so as to pass the separation panel, and an outlet extending from the chamber portion.

  • Publication number: 20050263448
    Abstract: A system for treating a fluid comprising solids and particulates where the system includes a separation device that includes a chamber having an outlet and an inlet, and a separation panel within the chamber that is located above and in fluid communication with the inlet, where the separation panel includes a plurality of openings sized smaller than the solids and larger than the particulates. The separation panel also includes a plurality of deflectors to deflect the solids away from the separation panel while the fluid passes through the openings in the separation panel to remove the solids from the fluid. The inlet is preferably located tangentially to the separation panel.

The separation panel also includes a plurality of deflectors to deflect the solids away from the separation panel while the fluid passes through the openings in the separation panel to remove the solids from the fluid. The system also includes a maturing area, in fluid communication with the separation device, to receive the fluid, where one or more additives are added to the fluid in the maturing area to create formed and enlarged particles from the particulates in the fluid, and where the formed and enlarged particles are removed from the fluid by the separation device.
