1. 21. Nitrous oxide emissions from deammonification process under different operation conditions.

   Master-uppsats, KTH/Mark- och vattenteknik

   Författare :Agnieszka Mazurek; [2015]
   Nyckelord :Anammox; Deammonification; Kaldnes; MBBR; Nitrous oxide;

   Sammanfattning : Wastewater treatment plays significant role in the environmental protection. The process has direct impact on quality of air and water. All treated sewage reaches fresh water reservoirs as well as gasses escaping from the process are emitted to the atmosphere. LÄS MER

3. 22. High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Gabriel Persson; [2015]
   Nyckelord :methane potential; High-loaded activated sludge; activated sludge modelling; aeration strategies; ASM2d; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental engineering; Technology and Engineering;

   Sammanfattning : The activated sludge process has existed for over a century and despite its age the development of new theories, methods and technologies is ongoing. Despite huge technological breakthroughs in the last decades the activated sludge process is still a very energy demanding process however, and it is possible to make significant energy savings by optimizing the aeration strategy of an activated sludge plant.

4. 23. Mainstream deammonification reac-tor at low DO values and employing granular biomass.

   Master-uppsats, KTH/Mark- och vattenteknik

   Författare :Marco Salmistraro; [2015]
   Nyckelord :ANAMMOX; Deammonification; Dissolved oxygen control; Granu-lar biomass; Mainstream municipal wastewater treatment; Partial nitrification;

   Sammanfattning : Nitrogen removal from wastewater has been exstensively addressed by scientific literature in recent years; one of the most widely implemented technologies consists of the combination of partial nitritation and anaerobic ammonium oxidation (ANAMMOX). Compared to traditional nitrification and denitrification techniques such solution eliminates the requirement for an external carbon source and allows for a reduced production of excess sludge; furthermore, it brings down the costs associated to aeration by 60-90% and the emissions of CO2 by 90%.

5. 24. 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

7. 25. 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
