Factors Affecting the Performances of Biomass Anaerobic Digestion Process
نویسنده
چکیده
The effect of heavy metals and light metals ions on anaerobic digestion of three agricultural biomasses (two row barley, wheat bran and a mixture of 75 % corn kernels and 25 % corncobs) was investigated in this study. The raw materials were characterized from physico-chemical point of view and their heavy metals content (copper, chromium, nickel, lead and zinc) and light metals ions content (potassium, magnesium, calcium and aluminum) was measured. The effects of these substances on the anaerobic activity were analyzed by measurements of cumulative biogas production and the methane content of the obtained biogas.

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 ...
