  • Biogas production and potential from U.S. Wastewater Treatment

    How many wastewater treatment plants (WWTPs) have anaerobic digestion? How many are utilizing the biogas? What percentage of these facilities are feeding additional substrates into their digesters? How is the biogas being used — is it flared, used to drive process machinery, heat the digester, or injected into a natural gas pipeline? These are some of the questions asked of the ...

  • The elimination of siloxanes from the biogas of a wastewater treatment plant by means of an adsorption process

    Siloxanes present in the biogas produced during anaerobic digestion in wastewater treatment plants (WWTPs) can damage the mechanism of cogeneration heat engines and obstruct the process of energy valorization. The objective of this research is to detect the presence of siloxanes in the biogas and evaluate a procedure for their elimination. A breakthrough curve of a synthetic ...

  • LCA applied to elucidate opportunities for biogas from wastewaters in Colombia

    Biogas produced in municipal and industrial wastewater treatment facilities (BWWF) is a resource wasted in several socio-economic contexts. BWWF-based projects are compared against energy projects using conventional electricity or natural gas (NG), following strict economic considerations that usually tip the balance in favour of conventional energy supply. This is because the economic gain ...

  • 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 ...

  • Energy potential and alternative usages of biogas and sludge from UASB reactors: case study of the Laboreaux wastewater treatment plant

    This work assessed the energy potential and alternative usages of biogas and sludge generated in upflow anaerobic sludge blanket reactors at the Laboreaux sewage treatment plant (STP), Brazil. Two scenarios were considered: (i) priority use of biogas for the thermal drying of dehydrated sludge and the use of the excess biogas for electricity generation in an ICE (internal combustion engine); ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Biogas-to-biomethane upgrading plant

    Chesterfield BioGas (CBG) supplied the UK’s first biogas upgrading plant to produce clean biomethane for direct injection into the national gas grid for use by all consumers. The project was successfully completed and gas injected into the national grid at the wastewater treatment site of Thames Water site at Didcot, Oxfordshire in October 2010. This achievement was a benchmark moment for ...

  • 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.

  • 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 ...
