Biological Pretreatment and Dry Digestion Processes for Biogas Production
Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process. Additiona...
متن کاملPotential errors in the quantitative evaluation of biogas production in anaerobic digestion processes.
Errors that are commonly made in the quantification of biogas from anaerobic digestion experiments were investigated. For liquid displacement gasometers where a barrier solution separates the biogas and the atmosphere, inaccuracy due to gas diffusion was examined experimentally. Acidified saturated saline solution was the most suitable barrier solution, as biogas characteristics changed least w...
متن کاملThe Potential for Biogas Production from Grass
Grass is generally considered as one of the major agricultural products and covers over 90% of Irish agricultural land. While useful as an animal feedstock it can also be used for energy production. Here batch mesophilic anaerobic digestion of grass silage was studied. The methane concentration in the biogas clearly showed that grass silage has a high affinity to produce a high quality methane ...
متن کاملa pilot plant for the biogas production
manure and putreseible garbage are some of the main sources of pathogenic germs in countryside’s. on the other hand, demand for fertilizer and energy increases in rural areas every day. to study potential of cow manure for these requirements a 16,5m3 pilot plant was designed and constructed as fermentation tank near animal husbandry of karaj agriculture faculty. some 260kg cow manure and water ...
متن کاملEffects of heavy metals as stress factors on anaerobic digestion processes and biogas production from biomass
Heavy metals affect the biochemical reactions that take place during anaerobic digestion processes of organic matter. In this review, the different effects observed in anaerobic digestion processes and during the production of biomethane and biohydrogen from several substrates contaminated with and/or inheriting heavy metals from the substrates themselves were discussed. It has been found that ...
