  1. 11. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Virginia Tosi; [2021]
    Nyckelord :Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Sammanfattning : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  3. 12. Fractionation of Wheat Bran for Utilisation in Biorefinery

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gabriella Haag; [2021]
    Nyckelord :Wheat bran; biorefinery; chemical engineering; vetekli; bioraffinaderi; extraction; Technology and Engineering;

    Sammanfattning : Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. LÄS MER

  4. 13. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Björn Sundqvist; [2021]
    Nyckelord :;

    Sammanfattning : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.

  5. 14. Muddringssystem förFiberbankar

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :JACOB ANDERSSON; [2021]
    Nyckelord :Dredging; fiber bank; sediment; Bottensediment; fiberbankar; muddring;

    Sammanfattning : Massa- och pappersindustrin i Sverige har genom åren skapat en stor mängd restprodukter i form av pappers- och träfiber och rester av processkemikalier från produktionen. Vidanläggningar på Sveriges östkust deponerades dessa ofta rakt ut i havet där fiber ackumulerats genom åren till fiberbankar. LÄS MER

  7. 15. Analysis of PFAS in ash from incineration facilities from Sweden

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Dennis Wohlin; [2020]
    Nyckelord :;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a group of organohalogens that bioaccumulate in biota, have toxicological effects and are persistent in the environment. Because of the fluorinated carbon chain, PFASs are present in many household and industrial products. LÄS MER
