  • Biogas cleaning / conditioning - A requirement for optimal functioning of CHP systems

    Biogas is obtained through the anaerobic decomposition (putrefaction) of organic matter. It contains methane (CH4) in varying proportions, ranging from 35% to 70%, a proportion which largely depends on production methods and the materials involved in the process. This methane concentration is what enables biogas to be used as fuel. The release of methane into the atmosphere contributes to an ...

  • Determination of the optimal rate for the microaerobic treatment of several H2S concentrations in biogas from sludge digesters

    The treatment of H2S in the biogas produced during anaerobic digestion has to be carried out to ensure the efficient long-lasting use of its energetic potential. The microaerobic removal of H2S was studied to determine the treatment capacity at low and high H2S concentrations in the biogas (0.33 and 3.38% v/v) and to determine the optimal O2 rate that achieved a concentration of H2S of 150 mg/Nm3 ...

  • Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge

    Thermal steam-explosion is the most extended hydrolysis pretreatment to enhance anaerobic digestion of sludge. Thermal hydrolysis key parameters are temperature (T) and time (t), and the generally accepted values reported from full-scale information are: 150–230 °C and 20–60 min. This study assesses the influence of different temperature–time–flash combinations (110–180 °C, ...

  • National brewery benefits from biogas

    Anheuser-Busch has installed anaerobic digestion systems at 10 of its 12 large breweries in the U.S., with an 11th system in design. Primary drivers are cost-avoidance for wastewater treatment fees and fossil fuel purchases. ANHEUSER-BUSCH, owner of 12 large breweries in the U.S., has committed to reduce its greenhouse gas emissions 5 percent from 2005 levels by 2010. The company is well ...

  • 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 ...


  • 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 ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...

  • Case study - Biogas desulfurization and siloxanes abatement

    MCFC project by CETAGUA (Mataró – Spain) Reducing the carbon footprint of our society is imperative. This can be achieved by capturing and confining anthropogenic CO2 emissions as well as by replacing fossil-based fuels with renewable or waste-derived fuels. MCFCs (Molten Carbonate Fuel Cells) are unique in being able to do both these things. Thanks to their operating ...

  • Optimal environmental benefits of utilising alternative energy technologies in Jordan

    With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and ...

  • Optimization of municipal sludge and grease co-digestion using disintegration technologies

    Many drivers tend to foster the development of renewable energy production in wastewater treatment plants as many expectations rely upon energy recovery from sewage sludge, for example through biogas use. This paper is focused on the assessment of grease waste (GW) as an adequate substrate for co-digestion with municipal sludge, as it has a methane potential of 479–710 LCH4/kg VS, as well as the ...

  • Pumps with extended service life for generating biogas from organic waste

    When regular commercial pumps are used to process organic waste, they typically wear out after only a short period of time. Liquids pumped under these conditions attack pumps from two different angles: first with highly abrasive additives and second with liquids that have highly fluctuating pH values and therefore a high level of chemical aggressiveness. These conditions are very tough on seals ...
