Density of dewatered sludge
WebNov 15, 2007 · The specific gravity of the sludge solids is probably around 1.3. 70% of the sludge is water. Sludge density = 62.4 lbs/ft3 * 1.3 * 30% + 62.4 lbs/ft3 * 1.0 * 70% = … WebFor example, if sludge contains 80 percent volatile suspended solids and 50 percent of them are destroyed through oxidation, the stabilized mass of sludge solids would be reduced to 60 percent of the initial mass. Typical solids contents of sludges at various stages of treatment are summarized in this chapter.
