ABSTRACT:
A method and apparatus for removing sludge from water, including separating the inorganic constituents or matter in the sludge, such as stones, gravel, etc., from the organic matter, such as wood, roots, etc. In a first stage, those constituents that are larger than a given size are separated out from the sludge, with inorganic and organic ones of these constituents being separated from one another, being cleaned, and being then provided for subsequent use. In a second stage, inorganic constituents that are larger than a minimum size are separated out from the remaining matter, are cleaned, and are then provided for subsequent use. In a third stage, water is removed from the inorganic and organic slurry of the remaining matter to form a thick sludge and effluent.
