3-12-4 Effect of Hydrothermal Reaction Conditions on Dewatering Performance of Sewage Sludge

Abstract

Hydrothermal treatment was conducted on sludge, and the filtration performance of treated sludge was evaluated. The effect of treatment conditions, such as cooldown time, sludge species and slurry concentration on dewatering performance in constant-pressure filtration was clarified. Cooldown time and sludge species affected on the filtration performance significant, but specific resistance of filtration was not changed depend on the slurry concentration.
