  1. 6. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Stéphanie Nyström; [2022]
    Nyckelord :Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Sammanfattning : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  3. 7. A COMPARATIVE STUDY OF TRAVELLING FIRE IN LARGE SPACES WITH MULTI-ZONE FIRE MODEL AND FDS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Paolo Bertoli; [2021]
    Nyckelord :Multi-Zone fire model; FDS; Large enclosures; Travelling fire.; Technology and Engineering;

    Sammanfattning : A knowledge of far field temperatures is valuable for Performance Based Design structural analysis and life safety analysis, where a parametric study is needed. A fire model using multiple zones called a multi zone (MZ) fire model has in previous studies shown good potential as an analytical tool for predicting far field temperatures in large compartments.

  4. 8. Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Malcolm Akner; [2021]

    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.

  5. 9. Development and Scaling Up of Test Protocol to a Full-Scale Filter Rig to Investigate Soft Particle Filtration Efficiency in Biofuel Blends

    Master-uppsats, KTH/Kemiteknik

    Författare :Saurabh Shinkhede; [2021]
    Nyckelord :Heavy duty transportation; fuel filter clogging; soft particles; biofuel blends; filter test rig; Tunga transport; igensättning av bränslefilter; mjuka partiklar; biobränsleblandningar; filtertestrigg;

    Sammanfattning : Kommersiella tunga transporter står för en stor del av utsläppen av växthusgaser. För att minska det globala fotavtrycket hos kommersiella fordon är det vanligt att använda biodrivmedel som ”drop in” bränslen. LÄS MER

  7. 10. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Serena Bianchi; [2021]
    Nyckelord :stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

    Sammanfattning : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. LÄS MER
