  1. 21. high loaded anaerobic mesophilic digestion of sewage sludge : An evaluation of the critical organic loading rate and hydraulic retention time for the anaerobic digestion process at Käppala Wastewater Treatment Plant (WWTP).

    University essay from Mälardalens högskola/Framtidens energi

    Author : Ibrahima Sylla; [2020]
    Keywords : Dewaterability; Mesophilic anaerobic digestion; Methane; Organic load rate; Renewable energy source; Sludge filterability; Wastewater treatment.; Avvattningsförmåga; mesofil anaerob rötning; metan; organisk belastning; förnybar energikälla; slammets filtrerbarhet; vattenrening;

    Abstract : Käppala wastewater treatment plant (WWTP) has, during a few years, observed an increase in organic loading rate (OLR) in the mesophilic anaerobic digester R100, due to an increased load to the WWTP. The digestion of primary sludge at Käppala WWTP is today high loaded, with a high organic loading rate (OLR) and low hydraulic retention time (HRT). READ MORE

  3. 22. Feasibility Study for Production of Biogas from Wastewater and Sewage Sludge : Development of a Sustainability Assessment Framework and its Application

    University essay from KTH/Energiteknik

    Author : Akash Som Gupta; [2020]
    Keywords : resource recovery; wastewater treatment; biogas; anaerobic digestion; energy recovery; sustainability assessment; SDG;

    Abstract : Clean water and renewable energy are essential requirements to build resilience towards the adverse effects of climate change and global warming. Advanced wastewater treatment options may provide a unique opportunity to recover various useful resources such as energy (biogas), fertilizers, minerals, and metals embedded in the wastewater stream.

  5. 24. Potential for mitigating GHG emissions at a Swedish wastewater treatment plant – a life cycle approach

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Nina Aldén; [2020]
    Keywords : GHG emissions; Wastewater treatment; Sewage sludge; Life cycle analysis; Mitigation; Carbon footprint; Global warming potential;

    Abstract : To meet the national and international climate goals every potential GHG mitigating effort needs to be addressed. The aim of this thesis is to investigate if the wastewater treatment plant (WWTP), Ekebyhov, can reduce its GHG emissions by making changes inthe treatmentprocess. The main GHGs emitted from WWT areN2O, CH4and CO2. READ MORE

  6. 25. Biochar as a carbon dioxide removal solution : An assessment of carbon stability and carbon dioxide removal potential in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Alessandro Corbo; [2020]
    Keywords : Climate change mitigation; biomass; pyrolysis; soil;

    Abstract : Biochar is increasingly gaining momentum in the context of climate change mitigation and its production in Sweden could potentially become a large-scale system. Carbon stability in biochar is a crucial factor to assess its the carbon sequestration potential. READ MORE
