  • The feasibility of trace element supplementation for stable operation of wheat stillage-fed biogas tank reactors

    The aim of this study was to investigate the effect of trace element supplementation on operation of wheat stillage-fed biogas tank reactors. The stillage used was a residue from bio-ethanol production, containing high levels of sulfate. In biogas production, high sulfate content has been associated with poor process stability in terms of low methane production and accumulation of process ...

  • Autogenerative high pressure digestion: anaerobic digestion and biogas upgrading in a single step reactor system

    Conventional anaerobic digestion is a widely applied technology to produce biogas from organic wastes and residues. The biogas calorific value depends on the CH4 content which generally ranges between 55 and 65%. Biogas upgrading to so-called ‘green gas’, with natural gas quality, generally proceeds with add-on technologies, applicable only for biogas flows >100 m3/h. In the concept of ...

  • Anaerobic digestion foaming in full-scale biogas plants: a survey on causes and solutions

    Anaerobic digestion foaming is a common operation problem in biogas plants with negative impacts on the biogas plants economy and environment. A survey of 16 Danish full-scale biogas plants on foaming problems revealed that most of them had experienced foaming in their processes up to three times per year. Foaming incidents often lasted from one day to three weeks, causing 20–50% ...

  • Effect of the solid content on biogas production from Jatropha curcas seed cake

    Anaerobic conversion of Jatropha curcas seed cake was studied in a five–litre working volume batch reactor at 30°C. Over a 60–day operating period, a slurry of seed cake in water at a 1 : 20 seed cake–to–water ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...

  • Anaerobic treatability and biogas production potential of selected in-mill streams

    Biochemical methane potential assays (BMP assays) were performed to study the potential of anaerobic treatment of in-mill wastewaters. The assay results indicated that condensate and the BCTMP effluent, which are currently treated with the anaerobic internal circulation reactors, were the best streams for anaerobic treatment because of their relatively high degradability (>80%) and initial rates ...
