ABSTRACT:
Thickening method and apparatus includes conventional settling vessel with moving rake and pickets at the bottom thereof to promote sludge settling and compression and a plurality of inclined passageways for upwardly flowing liquid. Upflowing liquid from the hindered settling feed is clarified in the inclined passageways from which a presettled semisolid mass flows downwardly into a detention zone of compressive thickening sludge. This interrelationship of inclined passageways and compressively thickening zone enhances the effectiveness of the thickening process.
