  1. 1. Pilot scale partial denitratation coupled anammox: an evaluation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Tobias Ellingsen; [2022]
    Nyckelord :mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Sammanfattning : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. LÄS MER

  3. 2. Anammox in IFAS reactor for reject water treatment

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

    Författare :Bingquan Chen; [2019]
    Nyckelord :Deammonification; IFAS; Online sensors; Partial nitritation Anammox; Reject water; Specific anammox activity;

    Sammanfattning : The aim of this study was to evaluate the performance of the integrated fixed-film activated sludge (IFAS) reactor achieving partial nitritation/anammox process to treat reject water after dewatering of digested sludge. During the study period, dissolved oxygen setpoint, aeration mode and inflow loading were changed to evaluate their influence on the process performance and efficiency in the reactor. LÄS MER

  4. 3. Monitoring of denitrifying activities in moving bed biofilm reactors with an ex-situ manometric batch test

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sofia Bårdskär; [2016]
    Nyckelord :water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : Emissions of reactive nitrogen to the environment is of major concern, e.g. since it is known to contribute to eutrophication and dead sea floors in water bodies. The capability to remove nitrogen from wastewater has therefore become a critical means of preserving and protecting the environment. LÄS MER

  5. 4. Evaluation of Nitration/Anammox process by bacterial activity tests.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Anna Mika; [2015]
    Nyckelord :Partial Nitritation Anammox process; Integrated fixed-film acti-vated sludge IFAS reactor; Batch tests; Specific Anammox Activity SAA ; Nitrate Uptake Rate NUR ; Oxygen Uptake Rate OUR ; Ammonium Oxi-dizing Bacteria AOB ; Nitrite Oxidizing Bacteria NOB ; Heterotrophic bac-teria;

    Sammanfattning : Partial Nitritation/Anammox process (deammonification process), by which occurs oxidation of ammonium to nitrogen gas by autotrophic bacteria in anaerobic conditions, considered to be cost-effective and environmentally friendly method of nitrogen removal. Present research work focuses on achieving a high nitrogen removal degree, thanks to Anammox bacteria, while providing the best performance of the ongoing process. LÄS MER

  7. 5. Manometric method for evaluation of anammox activity in mainstream anammox at Sjölunda WWTP

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Dóra Stefansdottir; [2014]
    Nyckelord :Activity test; anammox: mainstream; MBBR; temperature dependency; vattenförsörjnings- och avloppsteknik; Chemistry;

    Sammanfattning : Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity (SAA) was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. LÄS MER
