Maximizing biogas production from the anaerobic digestion

Biogas production from food-processing industrial wastes by anaerobic digestion Biogas production from food-processing industrial wastes by anaerobic digestion

2. Production of Biogas by Anaerobic Digestion

Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...

Modeling and Removal of Hydrogen Sulfide from Biogas Produced by Anaerobic Digestion

Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...

Effects 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 ...

Biogas Production Anaerobic digestion of grains diluted in process water from a wastewater treatment plant

In light of constant research regarding the development of alternate fuels, anaerobic digestion of grains diluted in process water from a wastewater treatment plant has been investigaed by starting biogas reactors to produce methane. The possibility of using the sludge from the reactors as fertilizer was also explored. The experiment ran for 90 days of which three days were used to collect samp...
