  • Energy recovery from biogas purification

    Energy recovery from biogas is becoming more common, but the processes are hampered with the presence of hydrogen sulfide (H2S). Biogas is a mixture of methane and carbon dioxide (CO2) and is often contaminated with toxic quantities of H2S. Sources of biogas are: municipal landfills that produce landfill gas (LFG), wastewater treatment plants, industrial plants, and large scale livestock farms. ...

  • Assessing Feasibility of Direct Drive Technology for Energy Recovery from Digester Biogas

    ABSTRACTThe Regional Municipality of Waterloo completed a study, with support from Environment Canada, to evaluate the feasibility of using direct drive technology to recover energy from digester biogas. The study identified that a 150 HP engine, operating at 54 % load, could be supported by the estimated gas production of 1560 m3/d with 63 % methane by volume. ...

  • Biogas recovery from a temperate climate covered anaerobic pond

    New Zealand has over 1000 anaerobic waste stabilisation ponds treating wastewater from farms and industry. Traditional anaerobic ponds were not designed to optimise anaerobic digestion to produce biogas and are therefore uncovered, releasing biogas to the atmosphere, which can cause odour problems and contributes to GHG emissions. The biogas production and treatment performance of an anaerobic ...

  • The Benefits of Biogas Conditioning

    Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

  • Treatment of Biogas Produced in Anaerobic Reactors for Domestic Wastewater: Odor Control and Energy/Resource Recovery

    Anaerobic municipal wastewater treatment in developing countries has important potential applications considering their huge lack of sanitation infrastructure and their advantageous climatic conditions. At present, among the obstacles that this technology encounters, odor control and biogas utilization or disposal should be properly addressed. In fact, in most of small and medium size anaerobic ...

  • 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 ...

  • What`s New? Biogas Power

    Technologies that connect the biogas line to the power line include cooling and clean up components, microturbines and reciprocating gas engines and control systems. TOP BILLING on the biogas to electricity stage typically goes to the microturbines and reciprocating gas engines. But in the theater of renewable energy from organics recycling, the show can’t go on without the supporting cast of gas ...

  • American Biogas Council Policy Update

    ABC staff and members met with White House staff, legislators and federal agency officials during a recent fly-in to Washington, D.C. The American Biogas Council is celebrating its fifth year as the association for the anaerobic digestion and biogas industries. The Council, with over 200 members and 8,000 stakeholders, is very active in legislative activities at both the federal and state ...

  • Electric Utilities Hook up To Biogas

    Pennsylvania Power & Light, Alliant Energy, Wisconsin Electric and Portland General Electric are some utilities that are plugging into anaerobic digestion projects. AT the October, 2001 BioCycle conference on “Renewable Energy from Organics Recycling,” the director of the Iowa Energy Center, Floyd Barwig, pointed out that the possibility of separating the United States from Middle ...


  • Cellulose recovery from municipal wastewater

    During Aquatech 2015 the Dutch technology developer Brightwork set in the spotlight the recovery of cellulose from waste water. The project Cellulose Assisted Dewatering of Sludge (CADoS) aims at separating cellulose fibres from toilet paper from waste water using finescreening technology. After separation the fibres serve as a filter aid for effective dewatering of biological sludge. The ...

  • Idex Environnement’s Biogas plant at Amiens - Case Study

    The Anaerobic Digestion (AD) plant in Amiens is operated by Idex Environment. The biogas is derived from the municipal solid waste (MSW) originating from the local area. Clarke Energy has delivered a full turnkey installation for this site, creating renewable energy. The engines supplied for this project are two JGMC ...

  • 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 ...

  • Potential biogas production from sludges and msw in Uruguay

    Sewage treatment Montevideo's sewage is disposed into the sea by means of an outfall. Nevertheless as there are a lot of cities that are not on seashore, and most of these cities are discharging their effluents into rivers without proper treatment, a more strict sewage treatment must be done in order to achieve the discharge standards. For the 1,780,000 inhabitants the current sewage coverage is ...

  • Biogas upgrading: Membrane separation takes over

    Abstract Due to governmental incentives and growing environmental awareness, it becomes increasingly attractive to upgrade biogas to natural gas quality and inject it into the natural gas grid or to use it as transport fuel. In this way, the biomethane can be utilized with the highest energy efficiency. Progressively, effort is being put into the utilization of organic waste streams in ...

  • A Summary of Available Analytical Methods for the Determination of Siloxanes in Biogas

    ABSTRACT The importance of measuring siloxanes has increased with the recent growth of the landfill-gas-to-energy (LFGTE) market. Siloxanes and other biogas impurities can form a residue upon combustion in engines that may increase maintenance and reduce engine lifetime.  A siloxanes analysis can assist with either determining if a bioaas purification system is needed, or if a system is ...
