13 Thickened sludge is to be digested angerobically in a standard

13 Thickened sludge is to be digested angerobically in a standard rate digester. The sludge is known to be 70% organic and 30% in organie in nature and have a total mass of solids = 3088 kg/dl. Approximately 60% of the organic fraction is converted to liquid and gaseous end produets after the digester period. The digested sludge consists of solids not converted to liquids and gases. Find the following: a) Organic fraction of the thickened sludge 6 b) Organic frachim remaining after digestion c) Inorganic fraction remaining after digestion. d) Total mess remaining after digestion e) If the digested sludge has a solids content of 5.0%. Use the formula below to calculate the Digested Sludge Accumulation Rate in m3/ V Total Mass Remaining (1000 kyon )(digested shadyp solids content)
