The disclosure concerns an apparatus for separating various sizes, shapes, and textures of solid particles from a liquid, comprising: a settling tank having an elongated ramp at one end with a scraper flight conveyor, driven at the upper end of the ramp, to scrape settlings from the bottom of the tank up the ramp out of the tank; and at least one cylindrical rotatable filter drum assembly snapped between spaced rigid guide and supporting brackets in the tank. An axial end of the filter drum has a ball duct seating in a socket duct connected to the intake of a continuously-operating pump for circulating filtered liquid to the machine tools with a bypass into a clean tank that overflows into the settling tank. The other end of the filter drum assembly is axially outwardly resiliently pressed, such as by a spring against an opposite wall of the tank, to urge the ball and socket joint together. Flexible handle brackets are provided at opposite ends of the filter drum assembly for easy and quick manual removal of the filter drum for cleaning and/or replacement.
