Ultrasonic and Thermal Pretreatments on Anaerobic Digestion of Petrochemical Sludge: Dewaterability and Degradation of PAHs
Effects of different pretreatment methods on sludge dewaterability and polycyclic aromatic hydrocarbons (PAHs) degradation during petrochemical sludge anaerobic digestion were studied. Results showed that the total biogas production volume in the thermal pretreatment system was 4 and 5 times higher than that in the ultrasound pretreatment and in the control system, and the corresponding volatil...
متن کاملEffects of thermal hydrolysis on organic matter solubilization and anaerobic digestion of high solid sludge
Anaerobic digestion of sludge not only decreases the mass/volume of sludge, but also increases the production of energy-rich biogas. The effects of a thermal hydrolysis process (THP) on the solubilization of main organics of sludge, as well as the performance of the followed biochemical methane potential (BMP) tests under mesophilic condition (35 C), were systematically evaluated. Organic compo...
متن کاملIncreased Anaerobic Digestion Efficiency via the Use of Thermal Hydrolysis
Waste sludge is frequently treated by anaerobic digestion to kill pathogens, generate methane gas and reduce odors so the sludge can be safely land applied. In an attempt to reduce sludge volumes and improve sludge dewatering properties, the use of thermal hydrolysis (TH), a sludge pretreatment method, has been adopted by numerous wastewater treatment plants, among them being the District of Co...
متن کاملEffect of Thermal Hydrolysis on Anaerobic Digester Performance
Anaerobic digestion (AD) has been recently introduced as a promising technology for producing bioenergy around the world. Due to its especial characteristics, solid waste could be considered as a proper feedstock in the digester. Retention time (RT) and rate of biogas production are two major parameters affecting the efficiency of the process. The AD procedure of biogas production consists of h...
متن کاملPhosphorus Release and Thermal Hydrolysis Pretreatment Effects on the Dewatering Properties of a Bio-P Biosolid in Anaerobic Digestion
The use of biological phosphorus removal by activated sludge has been shown to have adverse effects downstream in the solids handling processes of anaerobic digestion. From struvite formation problems within the digesters to increased polymer dosage and dewatered biosolids solids content. The fundamental cause is unknown however phosphorus removal prior to anaerobic digestion has been shown to ...
