Cereal distillers grains, a by-product from bioethanol industry, proved to be a suitable feedstock for biogas production in laboratory scale anaerobic digesters. Five continuously stirred tank reactors were run under ...

The hydraulic retention time (HRT) is one of the key parameters in biogas processes and often it is postulated that a minimum HRT of 10-25 days is obligatory in continuous stirred tank reactors (CSTR) to prevent a washout ...

© 2016 Elsevier LtdThe effects of hydraulic retention time (HRT) reduction at constant high organic loading rate on the activity of hydrogen-producing bacteria and methanogens were investigated in reactors digesting thin ...

© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. Spatial separation of metabolic stages in anaerobic digesters can increase the methane content of biogas, as realized in a tube anaerobic baffled reactor. Here, ...
