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 ...

  • 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 ...

  • 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 ...

  • Sustainable supply networks – II: frameworks at the company level and field studies

    In line with the values and characteristics argued in Berke and Satir (2011), two frameworks are developed at company level in this sequel article: one for legacy supply chains and the other for future supply networks. A survey is designed and conducted to assess the level of contribution each characteristic makes in transforming a company from a not sustainable legacy stage to a future ...

  • 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, ...

  • Influence of different organic amendments on the leaching and dissipation of Terbuthylazine in a column and a field study

    Received for publication April 9, 2008. Terbuthylazine (TA) is a herbicide that has been introduced for weed control in corn cultivations as a direct replacement for atrazine. Because incorporation of different organic amendments (OAs) is a common practice in this crop, this study investigated the effects of different OAs, including urban sewage sludge, poultry compost, and corn straw on the ...

  • Granular ferric hydroxide adsorbent for phosphate removal: demonstration preparation and field study

    Ferric hydroxide (FHO), which has high phosphate adsorption capacity, was prepared by precipitation at industrial scale and then fabricated via the drum granulation method with cross-linked poly(vinyl alcohol) as the binder. The optimum binder/FHO powder ratio was 0.6 for producing a granular adsorbent with a high phosphate adsorption capacity and stability. The Langmuir maximum adsorption ...

  • Point-of-use chlorination of turbid water: results from a field study in Tanzania

    Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household level, and limited data on whether dosing guidelines ...

  • Energy performance indicators of wastewater treatment: a field study with 17 Portuguese plants

    The energy costs usually represent the second largest part of the running costs of a wastewater treatment plant (WWTP). It is therefore crucial to increase the energy efficiency of these infrastructures and to implement energy management systems, where quantitative performance metrics, such as performance indicators (PIs), play a key role. This paper presents energy PIs which cover the unit ...

  • 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 ...

  • Experimental study on calcium carbonate precipitation using electromagnetic field treatment

    The present study investigated the effectiveness of electromagnetic fields in preventing calcium carbonate (CaCO3) fouling in cooling water.

  • Measurements of wind-induced loss of solid precipitation: description of a Norwegian field study

    Precipitation measurements have a well-documented and mostly wind-dependent bias which is especially apparent during solid precipitation events. The resulting inaccuracy in precipitation data remains an area of concern in quantifying regional and global climate trends. As a high-latitude country, Norway has many solid precipitation events often accompanied by high wind speeds where the current ...
