    Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

  3. 7. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Alexander Öhberg; [2022]
    Keywords : PFAS ELECTROCHEMICAL OXIDATION IN-SITU DESTRUCTION MINERALISATION REMOVAL;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. READ MORE

  4. 8. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

    University essay from SLU/Department of Molecular Sciences

    Author : Jessica Sellin; [2021]
    Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

    Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

  5. 9. The Structural Architecture of the Barsele Area, Sweden : Characterising the deformation events and mineralisation

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jaide Derbyshire; [2021]
    Keywords : Barsele; Structural Geology; Mineralisation; Deformation;

    Abstract : Located at an important intersect between orogenic Au deposits in Sweden’s Gold Line and volcanicmassive sulphide (VMS) deposits in the Skellefte Mining District, the Barsele area is of high interest.Currently, the Barsele deposit consists of the Norra VMS deposit and 3 intrusive-hosted orogenic Audeposits: Avan, Central, and Skiråsen which are hosted in a 1876 ± 10 Ma early orogenic granodiorite(Thomas, et al.

  6. 10. Reflection Seismic Survey for Characterising Historical Tailings and Deep Targeting at the Blötberget Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : EMMANUEL ALOFE; [2021]
    Keywords : reflection seismic; exploration; tailings; sustainability; circularity; tomography; reflektion seismisk; prospektering; gruvavfall; hållbarhet; cirkularitet; tomografi;

    Abstract : Iron has been an essential element to human development and iron-oxide deposits are known to host minerals that are labelled as critical raw materials (CRMs), especially in the EU. Therefore, ensuring a sustainable supply of CRMs require access to both primary and secondary sources of their host deposits such as iron oxides. READ MORE
