Aerobic thermophilic bacteria enhance biogas production
The enhancing effect of aerobic thermophilic (AT) bacteria on the production of biogas from anaerobically digested sewage sludge (methanogenic sludge) was investigated. Sewage sludge (5%, w/w) was incubated at 65°C with shaking for a few months to prepare the AT seed sludge. AT sludge was prepared by incubation of the AT seed sludge (5%, v/v) and sewage sludge (5%, w/w) at 65°C with shaking. The ...

Decolorization and biogas production by an anaerobic consortium: effect of different azo dyes and quinoid redox mediators
The inhibitory effect of azo dyes and quinoid compounds on an anaerobic consortium was evaluated during a decolorization process and biogas production. In addition, the impact of quinoid compounds such as lawsone (LAW) and anthraquinone-2,6-disulfonate (AQDS) on the rate of decolorization of Direct Blue 71 (DB71) was assessed. The anaerobic consortium was not completely inhibited under all ...

Precise biogas flow measurement: Overcoming the challenges of changing gas composition
INTRODUCTION As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is ...

Effect of different solid concentration on biogas yield and composition during anaerobic fermentation process
The anaerobic fermentation experiments were carried out on a self-manufactured bench scale anaerobic digester with pig dung as feed material. Under mesophilic digestion condition, effects of different solid concentration of feed on characteristics of biogas production were investigated. Results showed that daily average biogas production rate and total biogas yield were increased with the ...

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 ...
