1. 6. Evaluation of the effect of different SCOD/TN ratios in a mainstream nitritation process

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Doaa el Halabi; [2017]
   Nyckelord :Partial nitrification; nitritation; microscreen; filtration; Chemical oxygen demand; moving bed biofilm reactor; Partial nitrification anammox; PNA.; Technology and Engineering;

   Sammanfattning : Avloppsvatten är rikt på organiskt material, det organiska materialet har med fördel använts för biogasproduktion. Den traditionella kvävereningsprocessen kräver organiskt material, därför har ett extern organiskt material använts. LÄS MER

3. 7. Innovative Control Strategies for the Partial Nitritation/Anammox Wastewater Treatment Process

   Master-uppsats, KTH/Energiteknik

   Författare :Evan Scott; [2016]
   Nyckelord :;

   Sammanfattning : The project undertaken in this thesis was proposed by IVL Swedish Environmental Research Institute and performed at their R&D facility Hammarby Sjöstadsverk as a part of the EU funded research project R3 Water. A single stage partial nitritation/Anammox system in a moving bed biofilm reactor (MBBR) was controlled using oxidation reduction potential (ORP) in order to evaluate its utility as control parameter.

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

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Emine Gülce Hepdarcan; [2016]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 9. 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

7. 10. 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%.
