  • 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 ...

  • 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. ...

  • 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 ...

  • Increasing methane content in biogas and simultaneous value added product recovery using microbial electrosynthesis

    Electrosynthesis of multi-carbon compounds from the carbon dioxide present in biogas is a nascent approach towards purification of biogas. Microbial electrosynthesis (MES) cells, fabricated using different electrode materials, were operated using different electrolytes and mixed anaerobic culture as biocatalysts in the cathodic chamber under an applied cathode potential of −0.7 V vs standard ...

  • 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 ...

  • Biogas desulfurization and biogas upgrading using a hybrid membrane system – modeling study

    Membrane gas permeation using glassy membranes proved to be a suitable method for biogas upgrading and natural gas substitute production on account of low energy consumption and high compactness. Glassy membranes are very effective in the separation of bulk carbon dioxide and water from a methane-containing stream. However, the content of hydrogen sulfide can be lowered only partially. This work ...

  • 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 ...

  • 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 ...

  • Microturbines, Gas Engines Link Biogas to the Grid

    OPPORTUNITIES to produce electricity from methane are being improved continuously as manufacturers introduce new and upgraded equipment to address market needs and varying characteristics of raw biogas. In the renewable energy from organics recycling arena, the two primary types of electricity generation equipment are microturbines and reciprocating gas engines. This article provides a brief ...

  • 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 ...

  • Energy Recovery in Urban Wastewater Treatment on Global Scale

    ABSTRACT The lack of proper wastewater treatment results in production of CO2 and CH4 without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO2 and CH4 emissions associated with wastewater discharges could reach the equivalent of 3.13·105 tCO2·d-1 in 2025, with ...

  • Clarke Energy applauded for its ongoing adaptation to the biogas market

    French magazine Energie Plus has put Clarke Energy forward as a good example of a traditional key player adjusting to the constant developing biogas sector.

  • Making pressurized water scrubbing the ultimate biogas upgrading technology with the DMT Carborex® PWS system.

    Abstract Biogas is one of the most promising energy sources for the future. Biogas is a “waste” product from e.g. landfill sites or digesters that can be applied as a green and renewable energy source with no global emissions on CO2 and hardly no local emissions on other pollutants. Currently most biogas is used at a CHP at which a large part of the energy ...
