Waste-sludge treatment in the CPI (Chemical Process Industries)
A discussion of the operational principles and the design approaches covers chemical pretreatment; thickening by gravity or flotation; dewatering by centrifugation, various filtration techniques, or heat treatment; treatment of biological sludges from secondary wastewater by aerobic or anaerobic digestion; chemical fixation; by-product recovery, including metals from spent catalysts; and performance data on the treatment of CPI solid wastes, including oily, greasy, and asphaltic petrochemical wastes, which are thickened by flotation to a concentration of 2-5Vertical Bar3< solids, and dewatered by pressure filtration to 10-40Vertical Bar3< solids content, with Vertical Bar3: 99Vertical Bar3< solids capture.
