Effect of biopolymer on the dewatering characteristics of autothermal thermophilic aerobic digestion of sludges.

Abstract

Autothermal thermophilic aerobic digestion of sludge is known to produce poorly dewatering sludges. Laboratory studies were conducted to investigate the reasons for the poor dewatering. It was found that, during digestion, proteins and polysaccharides were released into solution, and that these could be linked to the deterioration in dewatering. The… (More)
