  1. 6. Evaluation of a gross pollutant trap-biofilter stormwater treatment train : The Role Of Calcium Carbonate, Vegetation And Pre-Treatment Facility

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Sofia Fahlbeck Carlsson; [2021]
    Keywords : Bioretention; stormwater; stormwater treatment; stormwater pollutants; heavy metals; phosphorus; Biofilter; dagvatten; dagvattenrening; dagvattenföroreningar; tungmetaller; fosfor;

    Abstract : Development of cities, new buildings and other impervious surfaces entails increased stormwater flows, volumes and pollutant loads. Heavy metals, nutrients, sediments and salt are common pollutants in stormwater. READ MORE

  3. 7. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Claes Sjöberg; Jens Kårhammer; [2021]
    Keywords : strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Abstract : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. READ MORE

  4. 8. Mineralogical and Geochemical Study of Acid Mine Drainage from 100 Years of Coal Mining in Svalbard (78° N)

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

    Author : Andreas Rehn; [2020]
    Keywords : Acid rock drainage; Acid mine drainage; coal mine waste; Pyrite; Arctic; Svalbard; Spitzbergen;

    Abstract : Waste rock piles from coal mining of tertiary bituminous coal in Longyearbyen, Svalbard, show sulfide oxidation and subsequent acid mine drainage (AMD) production. The aim was to establish deeper understanding of AMD prediction based on Mineralogy and Geochemistry of coal and AMD samples. READ MORE

  5. 9. Marktäckande material som åtgärd för minskat fosforläckage från rasthagar för värphöns

    University essay from SLU/Dept. of Soil and Environment

    Author : Ebba Hellstrand; [2019]
    Keywords : utehöns; fosforbindningsförmåga; punktbelastning;

    Abstract : Today there is a knowledge gap about phosphorus leakage from free range laying hens, and because of that a pilot project is ongoing since 2016 with scientists at The University of Agricultural Sciences (SLU), Research Institutes of Sweden (RISE) and also advisors in order to investigate the nutrient load from free range laying hens. My thesis have been conducted within this project, and I have chosen to focus on phosphorus leakage. READ MORE

  6. 10. Study of the Performance of Peat Moss Pyrolysis

    University essay from KTH/Materialens processteknologi

    Author : Yuming Wen; [2019]
    Keywords : peat moss; pyrolysis; bio-acids;

    Abstract : Peat moss, also called sphagnum, has become a big problem in many countries such as China and Sweden due to its high green-house gas emission from chemical and biological degradation. In this work, the performance of peat moss pyrolysis has been studied, to investigate the potential of application of peat moss pyrolysis on fuel and chemical production. READ MORE
