  1. 11. Evaluation of the suppressive effect of intermittent aeration on nitrite-oxidising bacteria in a mainstream nitritation-anammox process

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Amanda Okhravi; [2015]
    Keywords : Activity tests; anammox; AOB; Manammox; nitritation; NOB; OUR.; Aktivitetstester; anammox; AOB; Manammox; nitritation; NOB; OUR.;

    Abstract : An alternative to conventional removal of nitrogen through autotrophic nitrification and heterotrophic denitrification is autotrophic nitritation-anammox. The anammox bacteria oxidise ammonium directly to nitrogen gas with nitrite as an electron acceptor. READ MORE

  3. 12. Evaluation of Nitration/Anammox process by bacterial activity tests.

    University essay from KTH/Mark- och vattenteknik

    Author : Anna Mika; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 13. Study on one-stage Partial Nitritation-Anammox process in Moving Bed Biofilm Reactors: a sustainable nitrogen removal.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Andrea Bertino; [2011]
    Keywords : Anammox Biofilm; Deammonification; CANON; Moving Bed Biofilm Reactor; Re-ject water;

    Abstract : In the last decade, several novel and cost-effective biological nitrogen removal technologies have been developed. The discovery of anaerobic ammonium oxidation (Anammox), about 15 years ago, has resulted in new opportunities for research and development of sustainable nitrogen removal systems. READ MORE

  5. 14. Evaluation of microbiological activity during the deammonification process for nitrogen removal.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Weronika Wójcik; [2011]
    Keywords : Anammox; Moving Bed Biofilm Reactor; nitrogen removal; batch test; Specific Anammox Activity; Oxygen Uptake Rate; Nitrate Uptake Rate;

    Abstract : This master thesis is based on own studies. A four-month study was performed at Hammarby Sjostad Research Station, which is located in Stockholm. One-stage deammonification process was evaluated in two different system configurations in pilot plant scale. READ MORE
