BACKGROUND: Treatment methods for improved anaerobic digestion (AD) of waste activated sludge were evaluated. Pretreatments at moderate thermal (water bath at 80 • C), high thermal (loop autoclave at 130-170 • C) and thermo-chemical (170 • C/pH 10) conditions prior to AD in batch vials (40 days/37 •
## Abstract The influence of different pre‐treatments was studied in order to observe the effects of temperature, pH and treatment time on Waste Activated Sludge (WAS) solubilization, and anaerobic digestion of pre‐treated sludge. Results showed that thermo‐chemical pre‐treatments were the most eff
