  1. 1. 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

  3. 2. 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

  4. 3. 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
