  1. 1. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

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

    Författare :Harry Tibbetts; [2023]
    Nyckelord :Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Sammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER

  3. 2. Reduction of Acrylamide in Reject Water from Sludge Dewatering

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

    Författare :Martina Aspegren; [2023]
    Nyckelord :Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Sammanfattning : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. LÄS MER

  4. 3. Future sludge management from a sustainability perspective

    Master-uppsats, KTH/Proteinvetenskap

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

    Sammanfattning : 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. LÄS MER

  5. 4. Modeling of the primary sludge thickening process at a wastewater treatment plant with the use of machine learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Eric Bröndum; [2022]
    Nyckelord :Machine Learning; Stockholms Vatten och Avfall; Primary Sludge; Dewatering; Wastewater Treatment Plant; Simulation; time series prediction; Maskininlärning; Stockholms Vatten och Avfall; Primärslam; Förtjockning; Avloppsreningsverk; Simulering; Tidsserieprediktion;

    Sammanfattning : This thesis focuses on modeling the primary sludge in the thickening process at Henrikdals wastewater treatment plant in Stockholm, Sweden. The thickening process is one of the core processes at the wastewater treatment plant, where the goal is to thicken a residual product called primary sludge. LÄS MER

  7. 5. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Louise Hjalmarsson; [2021]
    Nyckelord :hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

    Sammanfattning : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. LÄS MER
