1. 1. Character and Function of Anammox Bacteria under Environmental Stress

   Författare :Ola Bäckman; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anammox; N-cycle; environmental stress; redox oscillations; anammoxosome; key proteins;

   Sammanfattning : During the last few decades observations of novel processes involved in nitrogen transformations have fundamentally challenged the view of pathways and controlling mechanisms during local and global nitrogen cycling. Anaerobic ammonium oxidation (anammox) constitutes one of these new pathways where autotrophic bacteria oxidize ammonium by nitrite to dinitrogen gas under anaerobic conditions. LÄS MER

3. 2. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

   Författare :Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER

4. 3. Performance and control of biofilm systems with partial nitritation and Anammox for supernatant treatment

   Författare :Beata Szatkowska; Elzbieta Plaza; Bengt Hultman; Peter Balmér; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkalinity; Anammox; conductivity; partial nitritation; pH; removal rate; supernatant; Environmental engineering; Miljöteknik;

   Sammanfattning : Separate treatment of supernatant with dewatering of digested sludge with application of partial nitritation/Anammox process is assessed to be a cost-effective way to remove about 10-15% of influent nitrogen and, thereby, facilitate possibilities to reach required effluent requirements from the plant. The combined partial nitritation/Anammox process can be performed in two separate reactors or in one-stage. LÄS MER

5. 4. Partial Nitration/anammox process in the moving bed biofilm reactor operated at low temperatures

7. 5. Microbial communities in anammox and nitrifying biofilms

   Författare :Carolina Suarez; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

   Sammanfattning : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. LÄS MER
