  • Development of on-line and field dual TD GC – MS for automatic VOC monitoring on petrochemical sites

    Ambient air is polluted by many semi-Volatile and Volatile Organic Compounds (SVOCs and VOCs) coming from anthropogenic and natural sources. VOCs from PAMS, TO14 and TO15 lists can be measured in many ranges of concentration, from pg/m3 up to mg/m3 depending on the location of the measurements. Due to the large number of molecules, the complete separation of all compounds is difficult to perform ...

  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • Study of the use of thermoluminescent materials in mixed fields

    The scientific research and the application of the thermoluminescence phenomenon have been advancing for the last two decades. Thermoluminescent Detectors (TLDs) present advantages when used in dosimetry. These advantages include reduced size and the non-use of wires. As a disadvantage, we see the loss of all signals after the reading (information) of the detectors. In the present study, we used ...

  • Tengiz oil fields, Kazakhstan case study

    Client: Chevroil CSG supplied a half kilometre stretch of D400 Translinea to the Oil and Sulphur fields in Kazakhstan. The site, operated by Chevroil, is located on the shores of the Caspian Sea in North West Kazakhstan and covers some 970 square miles. It is the sixth largest oil field in the world holding an estimated 25 Billion barrels. When running at full capacity the area is capable of ...

  • From gasworks to playing field case study

    There had formerly been a gasometer on this site, which had contaminated 3000 cubes of soil with an average TPH of 6,500mg/kg and an average PAH of 400mg/kg. Sanctus, the contractor for the work, were looking for a way of treating the soil on site and avoiding any landfill costs. We suggested to them that they apply two litres of Alga Power 101, our unique seaweed-based media, with 100g of ...

  • Super BirdXPeller PRO: Wrigley Field - Case Study

    Wrigley Field, home of the Chicago Cubs, celebrated its 90th season in 2003. As Wrigley Field prepared to play host to all of the Cubs’ NL rivals, the stadium also battled an unwelcome new preseason one: pigeons found a home in the upper deck. The Problem It isn’t only Cubs fans who love Wrigley Field. “Pigeons like to roost on the trusses that support the upper ...

  • Field Dewpoint Measurement - How Good Are We ? - Case Study

    Recently BJ PPS Leeds dried a client system with nitrogen. Dewpoint was measured using a Michell ADM dewpoint meter which was connected to the system at different locations via a one metre long rubber hose. The instrument was allowed to stabilise for approximately five minutes before each reading was taken. Average result was in the region of -27.5 °C. A check of our nitrogen supply and the ...

  • Biological ammonia removal field studies for drinking water treatment

    In order to study the applicability of biological ammonia removal from drinking water, field experiments with 10 L/h flow rate were carried out at a case-study area, where raw water contained arsenic, iron, manganese, dissolved gases (methane, aggressive carbon dioxide) and ammonia. The technology applied at the waterworks consisted of potassium permanganate (KMnO4) dosing and rapid sand ...

  • VENTUS-X-UMB field test in Norway - Case Study

    In a project, launched in January 2016, the Norwegian airport systems integrator Avinor has tested a new VENTUS-UMB model with an enhanced heating power. Two of the new models have run in the field, installed at the most extreme sites in Norway, where they are delivering wind data reliably ever since their installation. One is placed at the top of Kjølen mountain, close to Tromsø ...

  • Use of terrestrial field studies in the derivation of bioaccumulation potential of chemicals

    Field‐based studies are an essential component of research addressing the behavior of organic chemicals, and a unique line of evidence that can be used to assess bioaccumulation potential in chemical registration programs and aid in development of associated laboratory and modeling efforts. To aid scientific and regulatory discourse on the application of terrestrial field data in this manner, ...
