ABSTRACT:
Discloses transportable liquid clarifying and screw conveyor/compactor liquid-solid separator apparatus which includes a pressureable clarifier vessel portably mounted on a base with a top and sides converging to the bottom of the vessel for attachment to a sludge disposal apparatus. A sludge inlet enters the top of the vessel and extends to near the bottom of the vessel. An effluent discharge flow control valve is connected through a conduit in the top of the vessel to provide a designated back pressure within the vessel while controlling the discharge flow of effluent liquid from the vessel. The sludge disposal apparatus includes an elongated screw conveyor/compactor mounted at an angle and extending upwardly from the vessel bottom. The compactor housing is tapered to compact the sludge as the screw conveyor carries the sludge to a liquid extraction section. The liquid extraction section has a screen tapered to further compact the slurry while extracting liquid being forced out of the slurry. The liquid extractor section is formed of a tapered screw rotatable within a tapered screen body formed of longitudinally extending, circumferentially spaced apart ribs or bars with the circumferential spacing being the screen openings.
