  • Pt. 2 - IN the MIX - Construction Safety and Gas Detection

    This is part 2 of our 4 part series on Gas detection in the Construction Industry. With so many OSHA regulations, where do we begin to search for help with gas detection or respiratory protection within confined spaces? To start, OSHA has a web tool called the OSHA Construction “eTool”. ...


  • Digester Developers Target Mixed Organic Waste Streams

     emerging group of commercial companies see a viable business opportunity in North America around building, owning and operating larger scale anaerobic digestion (AD) facilities to process mixed organic waste streams. In some instances, the projects being proposed and constructed only include anaerobic digester operations. In others, there is a combination of digestion with back-end ...

  • In situ and laboratory toxicity of coalbed natural gas produced waters with elevated sodium bicarbonate

    Some tributaries in the Powder River Structural Basin, USA, were historically ephemeral, but now contain water year round as a result of discharge of coalbed natural gas (CBNG)‐produced waters. This presented the opportunity to study field sites with 100% effluent water with elevated concentrations of sodium bicarbonate. In situ experiments, static renewal experiments performed simultaneously ...

  • Optimising laboratory environment for successful IVF outcomes with Geotech’s G100

    The accuracy of incubator gases within an IVF laboratory plays a major role in success of IVF programs in any fertility clinic today. Given the crucial role that the incubator plays in the IVF process, the conditions within the incubator in an IVF laboratory must be optimal at all times to increase the likelihood of a successful assisted reproductive treatment. Geotech’s ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Velocity gradient as a tool to characterise the link between mixing and biogas production in anaerobic waste digesters

    Whilst the importance of mixing in anaerobic digesters to enhance process performance and gas production is well recognised, the specific effects of mixing regime on biogas production are not clear. Here, the velocity gradient is used to demonstrate the importance of minimally mixed zones in a digester, with computational fluid dynamics (CFD) models indicating that 20–85% of a ...

  • FORENSIC study at a Northern New Jersey service station: the mixing of old and new gasoline

    In 2000, a client purchased a gasoline service station in northern New Jersey. A few days after receiving possession of the property, he received a letter from a State regulatory agency informing him that an investigation surrounding a leaking waste oil UST was required. He was unaware that a waste oil UST had existed; automotive repairs were not part of his or the previous owner’s business ...


  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

  • Waste Gas Cleaning for Road Tunnels and Underground Car Parks

    The objective of the study was to find a microbiological cleaning technique for road tunnel waste air, with emphasis on CO, NO and NO2. The chemolithotrophic CO oxidizing mixed population with an integral part of nitrifying bacteria carry out an essential step in metabolic process of NOx consumption. The immobilized microorganisms were subsequently exposing them to a constant stream of artificial ...


  • Run cars on green electricity, not natural gas

    With the dramatic increase in oil prices earlier this year translating into higher prices at the gas pump in the United States, concerns over US dependence on foreign oil are once again part of the national discussion on energy security. Combined with the growing understanding that carbon emissions from the combustion of fossil fuels are driving global climate change, the debate is now focused on ...

  • Digester Developer Taps Natural Gas Markets

    IN the late 1990s, Dan Eastman and two colleagues were researching business opportunities in the renewable energy industry. They were looking for a commercially viable technology that could take renewable energy from an experimental phase to a solid business investment. In 1999, Eastman and his partners founded Microgy, Inc., with its base in Wisconsin. The company licensed the Xergi anaerobic ...

  • Treatment of Sugar Carbonatation Sludge for Reuse and Flue Gas Desulphurisation

    In this work sugar refinery carbonatation sludge is treated in a pilot scale facility for two purposes: reuse in the carbonatation process, mixed with fresh calcium hydroxide, and flue gas desulphurisation. The sludge is first dried, and then calcinated in a batch kiln with a capacity of 100 kg, designed for the purpose. This process is potentially attractive for the sugar industry, since it can ...


  • 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 ...
