    Abstract: A separating device is provided for separating liquid from a slurry of liquid and solid particles. The device has a settling chamber including a filter screen spanning a liquid outlet opening at the open top end of the settling chamber. A slurry inlet, in communication with the settling chamber below the filter screen, introduces a slurry of liquid and solid particles into the settling chamber. Liquid is urged to escape from the settling chamber upwardly through the filter screen. The filter screen, being located at the top of the settling chamber, provides a more natural separation of the liquid from the solid particles by permitting the liquid to rise upwardly through the screen while the solid particles settle out in the settling chamber to be compacted at the bottom of the chamber for removal of the compacted solids from the bottom of the chamber.
