1. 1. Mainstream Deammonification process monitoring by bacterial activity tests

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Andrea Carranza Muñoz; [2020]
   Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

   Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

3. 2. Evaluation of nitrite oxidizing bacteria (NOB) activity in the nitritation reactor of a two-stage partial nitritation-anammox (PNA) system operating at mainstream conditions

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Emine Gülce Hepdarcan; [2016]
   Keywords : MBBR; Nitrogen removal; Partial Nitritation-Anammox; Wastewater treatment; Z-200 carriers; AOB; NOB; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : Nitrification-denitrification process, which is the most commonly used method for nitrogen removal from wastewaters, is energy demanding and contributes very much to the the carbon footprint of wastewater treatment. One of the alternative methods for nitrogen removal is the nitritation-anammox process. READ MORE

4. 3. 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

5. 4. Optimization of biomolecular techniques for detection of nitrite-oxidizing bacteria

   University essay from Akademin för hållbar samhälls- och teknikutveckling

   Author : Sara Sydkull; [2009]
   Keywords : Nitrobacter; nxr; PCR;

   Abstract : Nitrification is a natural occurring, oxidative process which is essential for plants´ ability to take up nitrogen in the form of nitrate. The oxidation is divided into two steps. READ MORE
