removing h2s from anaerobic gas Articles

  • Cryogenic technology for the removal of h2s in wastewater treatment facilities

    Hydrogen sulfide (H2S; CAS No. 7783-06-4) gas production usually is one of the primary concerns in the wastewater treatment facilities.  Under anaerobic (septic) wastewater conditions, sulfides cannot be oxidized (Palmer, Lagasse, and Maureen 2011). Therefore, they combine with hydrogen to produce hydrogen sulfide gas, creating the "rotten egg" odor associated with septic wastewater (Palmer, ...

  • Treament of Hydrogen Sulfide (H2s)

    This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...

  • 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 ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

  • Two-phase thermophilic anaerobic digestion process for biohythane production treating biowaste: preliminary results

    This paper deals with the optimization of a two-phase anaerobic process treating biowaste for hydrogen and methane production. Neither physical nor chemical pre-treatments were used to optimize the process. The work was carried out at pilot scale, using two CSTRs (200 and 380 L working volume respectively) both maintained at thermophilic temperature (55 °C) and fed semi-continuously with ...

  • 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 ...

  • Generation using gas-fuelled engines in South Africa – an overview

    Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, ...

  • Solar grease trap aerator works day and night

    Solar Grease Trap Aeration Systems were developed to solve Odor and Water Quality Problems. Solar Grease Trap Aeration Systems will remove and avoid odor problems while also improving overall water quality without the need for Chemicals, Bacterias, and /or Ozone. This allows the restaurant owner to become more effective and efficient immediately. They can pay off the investment within 1-6 ...


  • 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 ...

  • 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 ...
