Sludge Drying

Dewatered sludge, or filter cake, is a highly viscous material in which the remaining water is mechanically trapped within the cake. For further drying, the cake must be broken up before heating to expose as much surface area as possible. This is difficult, because semisolid filter cake often takes on the characteristics of a heavy, sticky paste when efforts are made to break it up (PACE 1986). [Pg.69]

Sludge drying equipment does not always have to be expensive. Valley Plating Works Inc. of Los Angeles could not justify the expense of commercial dryers that it examined, which [Pg.69]


A pressure filter is a plate-and-frame press which operates on an intermittent time cycle. Drier cakes are generally attainable from a filter press. Sludge drying beds are usually used for smaller sludge volumes, which drain and dry rapidly. Thein appHcation is usually restricted to the more arid climates. [Pg.194]

Treatment methodologies for process solution wastes include pH adjustment, flocculation, precipitation of metals, dewatering and sludge drying. Chelated metals require special treatment to break the complexes. Chromium, cyanide, electroless plating, and printed circuit board wastes often need to be segregated from other streams in order to reduce waste volumes and avoid the chance that some complexed metals may escape the treatment system. [Pg.5]
