ABSTRACT:
This disclosure relates to apparatus for dehydrating or removing water from a liquid slurry such as sewage. The apparatus includes at least one vessel designed to receive a quantity of the slurry. At least one shaft is rotatably mounted above the vessel and has a plurality of spaced discs mounted on it. The lower part of each disc extends or dips into the slurry, and as the discs rotate a portion of the slurry adheres to the side surfaces of the discs. The water evaporates from the slurry on the portions of the discs that are exposed to the air. The concentrated slurry solids may be scraped from the sides of the discs and the solids settle to the bottom of the vessel. Means is provided at the bottom of the vessel for removing the solids.
