RISExogenous pH Buffer System with K2HPO4/KH2PO4 Addition Improving Thermophilic High-Solid Anaerobic Digestion of Waste-Activated Sludge
Publisher: ASCE
Abstract: Volatile fatty acids (VFAs) and ammonia accumulation showed high inhibition for the high-solid anaerobic digestion (HSAD) of waste-activated sludge. This study investigated the effects of an exogenous pH buffer system with ...
Semicontinuous Operation of One-Stage Autothermal Thermophilic Aerobic Digestion of Sewage Sludge: Effects of Retention Time
Publisher: American Society of Civil Engineers
Abstract: One-stage autothermal thermophilic aerobic digestion (ATAD) is a promising process for sewage sludge stabilization. This study investigated semicontinuous operation in simulated one-stage ATAD digesters and analyzed the ...
