  1. 1. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Santiago Elejalde Bolaños; [2022]
    Nyckelord :thermophilic anaerobic digestion; volatile fatty acids; mixed sludge; organic loading rate; alkalinity; wastewater treatment plant; termofil rötning; flyktiga fettsyror; blandslam; organisk belastning; alkalinitet; avloppsreningsverk;

    Sammanfattning : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. LÄS MER

  3. 2. Omställning från mesofil till termofil rötning på Hammarby Sjöstadsverket

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ilwad Ahmed; [2022]
    Nyckelord :Mesofil; termofil; rötning; biogas; slamhantering;

    Sammanfattning : I framtiden kommer belastning på Henriksdals avloppsreningsverk fördubblas, vilket innebär en ökning av antalet personer som bekännas, från cirka 800 000 till 1,6 miljoner. Hygienkravet på slam kommer även att bli striktare. LÄS MER

  4. 3. 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.

  5. 4. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Jessica Sellin; [2021]
    Nyckelord :Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

    Sammanfattning : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. LÄS MER

  7. 5. Hydrodynamic cavitation applied to anaerobic degradation of fats, oils and greases (FOGs)

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Johan Lunnbäck; [2016]
    Nyckelord :FOG; Hydrodynamic cavitation; Anaerobic digestion; Pre-treatment; Oil emulsion;

    Sammanfattning : To increase profitability for biogas production, new innovative substrates and condition of operations needs to be implemented. At the current state, fats, oils and greases (FOGs) represent a promising substrate even though it brings operational challenges to the anaerobic digestion process. LÄS MER
