  • 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 ...

  • Los Angeles County Sanitation Districts: Siloxane Removal

    Los Angeles County Sanitation Districts have long been involved with recovering landfill and digester gas for energy to power turbines and internal combustion engines. Their experience led them to identify performance issues associated with these gases. One particular challenge is siloxanes. Cyclic organic silicon monomers (siloxanes) used in the manufacture of personal hygiene, health care and ...

  • 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 ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • 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, ...

  • Biolimp siloxa for plant for biogas cleaning

    The biogas produced in a digester, landfill or waste water plant is normally treated in order to remove water, H2S, dust and/or CO2. The choice of the cleaning method employed and the compound to be removed depends on the type of end use of the gas. This paper focuses on desing, star up and operation of biogas cleaning plant for removal dangerous component (water, H2S, NH3, siloxane and ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • SolarBee Technical Bulletin

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
