  1. 11. 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

  3. 12. Factors increasing efficiency of deammonification process for nitrogen removal from mainstream wastewater.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Aleksandra Wur; [2014]
    Nyckelord :partial nitritation Anammox process; lab-scale reactors; batch;

    Sammanfattning : In recent years, the use of Anammox process for wastewater treatment has been thoroughly investigated. Currently, a major challenge is to use this process for the mainstream. LÄS MER

  4. 13. Systems for ammonium concentration for further removal in the partial nitritation/anammox technology.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :Isaac Owusu-Agyeman; [2012]
    Nyckelord :Ammonium; Anammox; conductivity; dissolved oxygen; ion-exchange; nitrogen; partial nitritation; regeneration; reverse osmosis;

    Sammanfattning : Anammox is one of the main processes discovered quite recently for removal of ammonium from wastewater. Anammox process is cost effective, in that low energy and carbon source is needed. LÄS MER

  5. 14. Application of Partial Nitritation/Anammox Process for Treatment of Wastewater with High Salinity.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :Xin Zhang; [2012]
    Nyckelord :Nitrogen Removal; Partial Nitritation; Anammox; SAA; OUR;

    Sammanfattning : The combination of partial nitritation and anaerobic ammonium oxidation (Anammox) is a composting way to remove the nitrogen in the wastewater. In this article the analysis was made to investigate how the salinity in the wastewater affects the process. Two strategies of salt concentration increase were tested in two reactors. LÄS MER

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

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

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

    Sammanfattning : 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. LÄS MER
