  1. 1. Towards sustainable water use in industry: a case study of the oil refinery industry in Kazakhstan

    Författare :Ivan Radelyuk; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial wastewater; oil refinery; Kazakhstan; groundwater contamination; groundwater modeling; contamination transport modeling; Sustainable water use; Environmental Impact Assessment; Circular Economy;

    Sammanfattning : The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and wellbeing of the society.

  3. 2. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer

    Författare :Zhibing Yang; Auli Niemi; Fritjof Fagerlund; Tissa Illangasekare; Insa Neuweiler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multiphase flow; dissolution; mass transfer; invasion percolation; immiscible displacement; fractured media; groundwater contamination; non-aqueous phase liquid; curvature; Hydrology; Hydrologi;

    Sammanfattning : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.

  4. 3. Tracing anthropogenic Technology Critical Elements using Environmental Forensics : Case studies at Kallholmsfjärden and the Bothnian Bay, northern Sweden

    Författare :Stacy Sutliff-Johansson; Anders Widerlund; Kristi Korkka-Niemi; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Forensics; Technology Critical Elements; Sediment Contamination; Groundwater Contamination; Contaminant Tracing; Tillämpad geokemi; Applied Geochemistry;

    Sammanfattning : The rapidly changing landscape of today's technology industry has increased the number of electronic products being discarded. Society is always on the hunt for the latest product and newest technological advancement, thereby creating a constant influx of older model products into fast-growing waste streams. LÄS MER

  5. 4. Predicting the transport of Escherichia coli to groundwater

    Författare :Emma Engström; Berit Balfors; Roger Thunvik; Nils-Otto Kitterød; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Groundwater contamination with pathogens poses a health risk worldwide. Predictive modeling could provide decision support for risk analysis in this context. This study therefore aimed to improve predictive modeling of the transport of Escherichia coli (E. coli) to groundwater. LÄS MER

  7. 5. Hydrogeological modeling to improve remediation strategies for a drinking water aquifer contaminated by an aqueous phase liquid

    Författare :Martin Bergvall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In many communities, groundwater is an important source of drinking water. Groundwater aquifers are, however, vulnerable to the widespread and increasing problem of contamination from anthropogenic sources. Once in the groundwater, contaminants are likely to remain there for a long time as the attenuation rate is slow. LÄS MER
