  1. 6. Volatile fatty acid production and application as external carbon source for denitrification

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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.

  3. 7. Polyhydroxyalkanoate Production from Municipal Waste Streams

    University essay from KTH/Resursåtervinning

    Author : Elsa Eriksson; [2020]
    Keywords : Polyhydroxyalkanoate; volatile fatty acids; mixed culture; bioreactor; municipal waste streams; Polyhydroxialkanoat; flyktiga fettsyror; blandad kultur; bioreaktor; kommunalt avfall;

    Abstract : Polyhydroxyalkanoates (PHAs) are a group of bioplastics, which are produced through microorganisms. They are accumulated in granules inside bacteria’s cell cytoplasm and serve as an energy reserve. READ MORE

  4. 8. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ross Roberts; [2020]
    Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

    Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

  5. 9. Space Transportation and Exploitation Missions offered by the VEGA Transportation System that could reshape the European Space Industry

    University essay from KTH/Farkost och flyg

    Author : Adrian Buzdugan; [2019]
    Keywords : Index Terms—AVIO; VEGA; VTS; VSS; Requirements; Kit approach; Modularity; Mission; Services; Space; Europe.;

    Abstract : The aim of the thesis is to provide the mission requirements for the VEGA Transportation System(VTS), the equivalent of Phase 0 of a space project. The decrease in sizes and masses of the satellites opened the opportunity for the light capability VEGA launchers to contribute and reshape the European space value chain. READ MORE
