  • 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 ...

  • Cleaning biogas with bacteria

    Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid ...

  • 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 ...

  • Anaerobic treatability and biogas production potential of selected in-mill streams

    Biochemical methane potential assays (BMP assays) were performed to study the potential of anaerobic treatment of in-mill wastewaters. The assay results indicated that condensate and the BCTMP effluent, which are currently treated with the anaerobic internal circulation reactors, were the best streams for anaerobic treatment because of their relatively high degradability (>80%) and initial rates ...

  • Influence of cyanide on the anaerobic degradation of glucose

    Bacteria in the anaerobic degradation process convert the substrate to the final products methane and carbon dioxide. Toxic substances can change the process substantially. The purpose of this study was to investigate the influence of toxic cyanide on biogas production in anaerobic degradation of glucose at 40°C. The OxiTop respirometric system offers a quick and simple method for measurement of ...

  • Evaluation of treatment potential, biogas generation and sludge properties of an anaerobic claridigester

    The anaerobic process for the treatment of municipal and industrial wastewater has been in practice for over a century. Apart from treatment of wastewater, the process has the advantage of lower sludge and biogas production that can save energy. Application of this process in a primary clarifier in such a way that there is simultaneous digestion of primary settled sludge and organic removal ...

  • Biogas in Asia

    The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM).   The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia ...

  • Aerobic thermophilic bacteria enhance biogas production

    The enhancing effect of aerobic thermophilic (AT) bacteria on the production of biogas from anaerobically digested sewage sludge (methanogenic sludge) was investigated. Sewage sludge (5%, w/w) was incubated at 65°C with shaking for a few months to prepare the AT seed sludge. AT sludge was prepared by incubation of the AT seed sludge (5%, v/v) and sewage sludge (5%, w/w) at 65°C with shaking. The ...

  • 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 ...

  • Background of biogas technology and its recent developments in Iran

    Biogas activities have been initialised since the mid 1970s in Iran. Only a few of about 70 rural projects are still active. Other activities include four municipal landfill gas extraction projects through which, two projects are being ready for power generation and some anaerobic treatment plants in industrial food processing factories. A modern research plant for practical investigation on ...

  • The hydrolysis and biogas production of complex cellulosic substrates using three anaerobic biomass sources

    In this study, the ability of various sludges to digest a diverse range of cellulose and cellulose-derived substrates was assessed at different temperatures to elucidate the factors affecting hydrolysis. For this purpose, the biogas production was monitored and the specific biogas activity (SBA) of the sludges was employed to compare the performance of three anaerobic sludges on the degradation ...
