Bioelectrochemical upgrading of anaerobic digester biogas under thermophilic conditions

IMPROVEMENT of BIOGAS GENERATION by COUPLING BIOELECTROCHEMICAL SYSTEMS to ANAEROBIC DIGESTION

Anaerobic Digester Feasibility Study

Continuously-stirred anaerobic digester to convert organic wastes into biogas: system setup and basic operation.

Anaerobic digestion (AD) is a bioprocess that is commonly used to convert complex organic wastes into a useful biogas with methane as the energy carrier. Increasingly, AD is being used in industrial, agricultural, and municipal waste(water) treatment applications. The use of AD technology allows plant operators to reduce waste disposal costs and offset energy utility expenses. In addition to tr...

Biogas production from different substrates in an experimental Continuously Stirred Tank Reactor anaerobic digester.

Different mixtures were digested in a single-stage, batch, mixed, laboratory scale mesophilic anaerobic digester at the Biomass Research Centre Laboratory (University of Perugia). The yield and the composition of biogas from the different substrates were evaluated and the cumulative curves were estimated. Two experimental campaigns were carried out, the first on three mixtures (chicken, pig and...

Anaerobic Co-digestion of Sewage Sludge with Cheese Whey under Thermophilic and Mesophilic Conditions

Anaerobic digestion of sewage sludge (SS) and co-digestion with cheese whey (CW) was evaluated in batch conditions under mesophilic and thermophilic regimens. Results indicated that the co-digestion can be successfully attained despite some inhibitory stages that may be initially present due to the accumulation of volatile fatty acids. Degradation of the mixture SS-CW followed a similar pattern...
