  • Hydrogen sulfide removal from livestock biogas by a farm-scale bio-filter desulfurization system

    A farm-scale biogas desulfurization system was designed and tested for H2S removal efficiency from livestock biogas. This work assesses the H2S removal efficiency of a novel farm-scale biogas bio-desulfurization system (BBS) operated for 350 days on a 1,000-head pig farm. Experimental data demonstrated that suitable humidity and temperature can help sulfur-oxidizing bacteria to form ...

  • Anaerobic Digester Hydrogen Sulfide Removal at the Manatee County, FL Southwest Water Reclamation Facility

    ABSTRACT The results of a full-scale trial initiated in May 2006 by the Manatee County Southwest Water Reclamation Facility are presented, and the impacts of peroxide regeneration of spent iron salts on the removal of hydrogen sulfide (H2S) from anaerobic digesters at the SWWRF are examined. Treatment with hydrogen peroxide was initiated in a thickened primary sludge line containing an average ...

  • Micro-aeration for sulfide removal in anaerobic treatment of high-solid wastewater: a pilot-scale study

    The presence of sulfur compounds (e.g. protein, sulfate, thiosulfate, sulfite, etc.) in the feed stream generates highly corrosive and odorous hydrogen sulfide during anaerobic digestion. The high sulfide level in the biogas stream is not only poisonous to many novel metal catalysts employed in thermo-catalytic processes; but also reduces the quality of methane as a renewable energy. This study ...

  • Sulfide removal from industrial wastewaters by lithotrophic denitrification using nitrate as an electron acceptor

    Sulfide is present in wastewaters as well as in biogas and can be removed by several physicochemical and biotechnological processes. Nitrate is a potential electron acceptor, readily available in most wastewater treatment plants and it can replace oxygen under anoxic conditions. A lab-scale reactor was operated for treatment of sulfide containing wastewater with nitrate as an electron acceptor ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Economical and Effective biogas process to Purify alternative fuels for Power generation

    Abstract 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 ...

  • Anaerobic digestion of wastewater from the fruit juice industry: experiments and modeling

    Anaerobic digestion of wastewater from the fruit juice industry was carried out in a batch digester. To study the effect of the pH values as well as the nutrient medium on the fermentation process, different parameters were monitored under mesophilic temperature, such as cumulative biogas volume, chemical oxygen demand (COD), total sugar, and biomass growth. It was found that for all cases, the ...

  • Development and Application of Biological H2S Scrubbers for Treatment of Digester Gas

    ABSTRACTAs part of the California Energy Group (Former California Energy Commission) Public Interest Energy Research (PIER) Program, biological hydrogen sulfide (H2S) biogas cleaning was evaluated. The biological H2S scrubber uses bacteria to oxidize the sulfide to produce both elementary sulfur and sulfuric acid. This system was tested at the Inland Empire Utilities Agency’s Regional Plant 1 ...

  • Xebec powers an energy revolution case study

  • Landfill Gas to Renewable Natural Gas Project Goes Ahead in Michigan

    Greenlane Biogas, a subsidiary of the Flotech Group of companies (founded in 1986), is pleased to confirm that it recently has received an order to build two 'Totara+' landfill gas upgrading systems to process 3200 scfm (approximately 5150 Nm3/hr) of gas to be injected into a local natural gas pipeline near Detroit Michigan. Greenlane Biogas, a developer and supplier of proprietary water ...

  • Biomethane production at Ontario wastewater treatment plant

    The City of Hamilton is purifying biogas and injecting it into the grid, while continuing to generate power and recover heat from its CHP system. Hamilton, Ontario, has long been a leader in producing biogas from its sewage and storm water wastes. Half a century ago, the city of 520,000 began processing sludge from its sprawling Woodward Avenue Wastewater Treatment Plant through anaerobic ...

  • Landfill gas to fleet fuel in Ohio

    In mid-September, the Solid Waste Authority of Columbus, Ohio (SWACO) cut the ribbon on Phase I of its Green Energy Center that will convert landfill gas to compressed natural gas (CNG) for use in CNG-powered cars and medium duty trucks. The facility will produce enough CNG annually to replace almost 250,000 gallons of gasoline, plus additional natural gas sufficient to generate electricity for ...

  • Defining solid waste

    Simultaneous to the publication of the final National Emission Standards for Hazardous Air Pollutants for Boilers (the Boiler NESHAP) and the Commercial and Industrial Solid Waste Incinerator (CISWI) Rules, EPA issued a new regulation that for the first time defines what materials are a non-hazardous solid waste when combusted. This rule, Solid Wastes Used as Fuels or Ingredients in Combustion ...
