  1. 1. The Potential of Dissolved Air Flotation for PFAS Reduction in Norrvatten's Future Waterworks

    Master-uppsats, KTH/Kemiteknik

    Författare :Madeleine Vikström; [2023]
    Nyckelord :PFAS4; drinking water production; dissolved air flotation; granular activated carbon filter; sludge management; PFAS4; dricksvattenproduktion; flotation; granulärt aktivt kolfilter; slamhantering;

    Sammanfattning : Norrvatten är en av Sveriges största dricksvattenproducenter. Med ett ökande behov av en större produktionskapacitet och nya regleringar, planerar dem att förbättra sin reningsprocess. En aspekt som kräver omfattande undersökning är val av reningsmetod för att nå den nya gränsen från Livsmedelsverket för fyra PFAS kemikalier. LÄS MER

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Susan Lan; [2023]
    Nyckelord :drought; water scarcity; land degradation; cotton Gossypium sp. ; synthetic textiles; viscose; lyocell; IKEA; agro-waste; poplar Populus sp. ; bamboo Bambusoideae ; sustainability;

    Sammanfattning : This degree project at the Swedish University of Agricultural Sciences has been conducted in collaboration with IKEA of Sweden. The textile industry contributes to significant environmental challenges, including pollution and global water scarcity. LÄS MER

  4. 3. A plant-based milk powder that functions as a substitution for regular milk powder

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Manon Scheffers; [2023]
    Nyckelord :spray drying; pant- based milk powder alternative; pea protein; food application; food engineering; Technology and Engineering;

    Sammanfattning : This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. LÄS MER

  5. 4. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Ludvig Dahlin; Ebba Larsson Regnström; [2022]
    Nyckelord :FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

    Sammanfattning : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

  7. 5. Protein content in Brewer’s spent grain and its characteristics : upcycling spent grain from food waste to protein source

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Moa Rönnhagen; [2022]
    Nyckelord :Barley; food waste; brewers’ spent grain; beer; protein; extraction; characterization; future food;

    Sammanfattning : The United Nations have adopted sustainable development goals (SDGs). Within these SDGs, food waste management and waste valorization, an increase in value, is found. For these reasons, it was of interest to study Brewers’ spent grain, a residual product from beer production. LÄS MER
