Abstract
Apparatus and method steps are provided for accomplishing the pressurized filtration of a slurry mixture to separate a liquid solvent constituent from a particulate solids constituent having particles with varied particle average diameters. The apparatus makes use of a novel generally-helical array of stiff-wire brush bristles contained within, and retained in position by, the frictional engagement with the interior surface of a cooperating tube-like, open-ended array peripheral enclosure.
