Effect of pre-aeration and inoculum on the start-up of batch thermophilic anaerobic digestion of municipal solid waste.
In this study, a short pre-aeration step was investigated as pre-treatment for thermophilic anaerobic digestion of the organic fraction of municipal solid waste (OFMSW). It was found that pre-aeration of 48 h generated enough biological heat to increase the temperature of bulk OFMSW to 60 degrees C. This was sufficient self-heating of the bulk OFMSW for the start-up of thermophilic anaerobic di...
متن کاملMixing effect on thermophilic anaerobic digestion of source-sorted organic fraction of municipal solid waste.
This paper examines the effect of mixing on the performance of thermophilic anaerobic digestion of source-sorted organic fraction of municipal solid waste during the start-up phase and in the absence of an acclimated seed. For this purpose, two digesters were used under similar starting conditions and operated for 235 days with different mixing schemes. While both digesters exhibited a successf...
متن کاملThermophilic Anaerobic Digestion of Municipal Solid Waste in Combined Process and Sequential Staging
Anaerobic digestion is an attractive method for waste stabilization with the potential generation of biogas and stabilized waste residue. Development of a treatment process at short digestion period with maximum process efficiency is the objective of this research. This paper presents the optimization performance between the combined anaerobic digestion and sequential staging concept in thermop...
متن کاملbiokinetics of anaerobic digestion of municipal waste
a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...
متن کاملMethanogenic population dynamics during start-up of anaerobic digesters treating municipal solid waste and biosolids.
An aggressive start-up strategy was used to initiate codigestion in two anaerobic, continuously mixed bench-top reactors at mesophilic (37 degrees C) and thermophilic (55 degrees C) conditions. The digesters were inoculated with mesophilic anaerobic sewage sludge and cattle manure and were fed a mixture of simulated municipal solid waste and biosolids in proportions that reflect U.S. production...
