  1. 1. Future sludge management from a sustainability perspective

    University essay from KTH/Proteinvetenskap

    Author : Ebba Simensen; [2023]
    Keywords : Sludge management; Waterworks sludge; Drinking water treatment; LCA; MCDA; Slamhantering; Vattenverksslam; Dirksvattenrening; LCA; MKA;

    Abstract : Syftet med projektet är att undersöka effekten av att leda över vattenverksslam från Norrvattens vattenverk, Görvälnverket, till Käppalaverkets reningsverk som ett steg i en mer hållbar slamhantering. Detta slamhanterings alternativ jämförs med en framtida lokal slamhantering vid Görvälnverket. READ MORE

  3. 2. Anaerobic digestion in continuous stirred tank reactors and plug flow reactors: : Comparison study concerning process performance

    University essay from KTH/Kemiteknik

    Author : Zeko Kocak; [2022]
    Keywords : Anaerobic digestion; municipal waste; continuous stirred tank reactor; plug flow reactor; biogas; Anaerob rötning; kommunalt avfall; kontinuerlig omrörd tankreaktor; pluggflödesreaktor; biogas;

    Abstract : Användningen av kommunalt avfall för att producera förnybar energi, huvudsaklig biogas, uppfyller 8 av Sveriges 16 miljökvalitetsmål. Två typer av rötningsprocesser som används är kontinuerligt omrörda tankreaktorer (CSTR) och pluggflödesreaktorer (PFR). READ MORE

  4. 3. Life and fracture in very high cycle fatigue of a high strength steel

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Daniel Karlsson; [2021]
    Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

  5. 4. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gabriella Corbee; [2021]
    Keywords : Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Abstract : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. READ MORE

  6. 5. Size optimization of constructed wetlands for phosphorus retention in agricultural areas

    University essay from SLU/Dept. of Soil and Environment

    Author : Anna Ferguson; [2019]
    Keywords : hydraulic load; digital elevation models; catchment;

    Abstract : Eutrophication is one of the main threats to the Baltic Sea and Sweden is not expected to reach its environmental target of No Eutrophication by 2020. Phosphorus (P) lossfrom terrestrial systems is one of the principal causes of eutrophication in water recipients and the need to decrease P loss from agricultural land is pressing. READ MORE
