  1. 1. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Fanny Blom; [2022]
    Nyckelord :wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

    Sammanfattning : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. LÄS MER

  3. 2. A case study of estimating Algal biomass productivity from wastewater treatment facilities in the state of Texas and possible use

    Master-uppsats, KTH/Kemiteknik

    Författare :Gopi Raju Makkena; [2022]
    Nyckelord :Microalgae; Rotating Algal Biofilm RAB ; Flash Hydrolysis; Algal biomass; Biofertilizer; Mikroalger; roterande algbiofilm RAB ; flashhydrolys; algbiomassa; biogödsel;

    Sammanfattning : För att hålla vattendragen och miljön rena, renas avloppsvattnet för att nå ett visst mått innan det släpps ut. Vi gjorde en fallstudie för att utvärdera metoderna som används för att behandla avloppsvatten i tre steg: primär, sekundär och tertiär i delstaten Texas, USA. LÄS MER

  4. 3. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sanna Sahlin; [2021]
    Nyckelord :Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. LÄS MER

  5. 4. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

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

    Författare :Johnny Hagelin; [2021]
    Nyckelord :Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

    Sammanfattning : Research about resource recovery from complex waste streams is getting an increased scientific attention since valuable resources can be produced by sustainable biological means. In anaerobic degradation processes, resources such as volatile fatty acids (VFAs) and biogas are highly coveted. LÄS MER

  7. 5. Volatile fatty acid production and application as external carbon source for denitrification

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

    Författare :Cora Michelle Döhler; [2020]
    Nyckelord :VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.
