  • Co-fermentation of sewage sludge and biowastes

    The anaerobic treatment of sewage sludge has a long history in Germany. It began early in the Twentieth Century with the development of the Imhoff tank and has, since then, been con-tinuously further developed. Today, anaerobic sludge digestion is the most widely used process for stabilizing sewage sludges. Digesters, in which a portion of the sewage sludge is converted into utilizable biogas ...

  • From fermentation residues to nutrient concentrate

    The growing number of bio-gas plants makes it in-creasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat fermentation residue substrates by suitable screening processes in such a way that they can be ...

  • From fermentation residues to nutrient concentrate

    Treatment of fermentation residue substrates from biogas plants by means of ceramic membranes The growing number of biogas plants makes it increasingly difficult to return the fermentation residue substrates to green spaces or arable land. Especially large-scale plants are often unable to find sufficient disposal possibilities in acceptable distances. Therefore it is sensible to treat ...

  • Effects of anaerobic fermentation residue of biogas production on the yield and quality of Chinese cabbage and nutrient accumulations in soil

    Field experiments were carried out to study the effect of different anaerobic fermentation residue of biogas production treatments on yield and quality of Chinese cabbage (Brassica rapa L. var. shanghaisis) and nutrient accumulation in soil. The results indicated that the yield and quality (Vitamin C and nitrate content) of Chinese cabbage were significantly improved. The highest yield of 1364.31 ...

  • 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 ...

  • Monitoring of digesters in biogas plants

    Renewable sources of energy are gaining steadily in importance. Leading the way is the use of methane gas obtained from fermentation processes in biogas plants. Overloading such plants with excessive biomass may have drastic economic consequences and may even inactivate the biomass, necessitating a cost-intensive restart. Adding too little biomass also has financial consequences, as less ...


  • Solution concepts for the production of biogas

    With its products that go to form part of biogas plants, it is not only a significant pioneering role that Hofstetter Umwelttechnik AG in Switzerland deserves. The company in Berne also adopts a leading position on the worldwide market for utilizing biogas. Hofstetter products – the socalled flares and compressor stations – are designed both for fermentation plants for biomass and for plants for ...

  • Energy from biogas

    From an ecological and economical perspective, biogas is an important source of energy. The fossil resources are limited, and they impose a high burden on the environment. A resourceconserving alternative made from biomass poses a different scenario. The raw material is renewable, and conversion only releases as much CO2 as was previously contained by the source material. With the technological ...

  • Ethanol by-product raises biogas output

    In 2007, the City of Fergus Falls, Minnesota undertook a study to evaluate adding thick corn stillage to the anaerobic digesters at its wastewater treatment plant (WWTP). The goal was to determine the potential for codigesting syrup with biosolids to increase biogas production, while avoiding operational and regulatory problems. The Fergus Falls WWTP operates three digesters in series, two ...

  • Latest analytical technology ensures biogas efficiency

    Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of ...


  • Peristaltic Pumps excel in Anaerobic Digestion & Biogas applications

    Biogas is a natural gas also known as biofuel or biomass and is produced by breaking down organic material such as household waste, manure and crops grown specifically for biofuel with temperature-sensitive microbes and capturing the by-products. In practice, it is difficult to find a pumping system for this application. Why? The pumps needs to handle fluid media as well as gas parts ...

  • Allweiler Peristaltic Pumps: an ingenious solution for biogas plants

    Installations and plants used to process biomass for the production of biofuels must be capable of handling difficult conditions. For example, intermediate products in the production of biodiesel exhibit a high level of chemical aggressiveness. Accordingly, pumps, pipe connections, and fittings must be capable of resisting these demanding conditions. In addition, waste products usually contain a ...

  • Case study - Optimising biogas generation in the UK and Germany

    Methane makes money. It generates energy revenues, carbon credits and is part of bio-treatment sludge processing. In most of the world it has only just begun. Measuring what we are doing and being responsible with this potentially damaging greenhouse gas makes good sense. With gas production for revenue, measurement is essential. While landfill gas analysis has been required for compliance with ...
