Anaerobic Codigestion of Sludge: Addition of Butcher's Fat

Apr 12, 2016· Fat waste discarded from butcheries was used as a cosubstrate in the anaerobic codigestion of sewage sludge (SS). The process was evaluated under mesophilic and thermophilic conditions. The codigestion was successfully attained despite some inhibitory stages initially present that had their origin in the accumulation of volatile fatty acids (VFA) and adsorption of long-chain fatty .

Investigation and Assessment of Sludge Pre-treatment .

The influence of disintegration of excess sludge on anaerobic digestion was studied in full scale. A stirred ball mill, an ultrasound disintegrator, a lysate centrifuge and an ozone treatment were used. The results of the degradation process was compared to a reference system without pre-treatment.
