  1. 16. Monitoring and controlling of deammonification process in pilot-scale IFAS system.

    University essay from KTH/Mark- och vattenteknik

    Author : Ewa Ograbek; [2015]
    Keywords : ;

    Abstract : In recent years, Anammox process has been investigated extensively. Today is successfully used for treatment of supernatant from dewatering of digested sludge having a high concentration of ammonia nitrogen. READ MORE

  3. 17. Evaluation of the suppressive effect of intermittent aeration on nitrite-oxidising bacteria in a mainstream nitritation-anammox process

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Amanda Okhravi; [2015]
    Keywords : Activity tests; anammox; AOB; Manammox; nitritation; NOB; OUR.; Aktivitetstester; anammox; AOB; Manammox; nitritation; NOB; OUR.;

    Abstract : An alternative to conventional removal of nitrogen through autotrophic nitrification and heterotrophic denitrification is autotrophic nitritation-anammox. The anammox bacteria oxidise ammonium directly to nitrogen gas with nitrite as an electron acceptor. READ MORE

  4. 18. Nitrous oxide emissions from deammonification process under different operation conditions.

    University essay from KTH/Mark- och vattenteknik

    Author : Agnieszka Mazurek; [2015]
    Keywords : Anammox; Deammonification; Kaldnes; MBBR; Nitrous oxide;

    Abstract : 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. READ MORE

  5. 19. High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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.

  6. 20. Mainstream deammonification reac-tor at low DO values and employing granular biomass.

    University essay from KTH/Mark- och vattenteknik

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

    Abstract : 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%.
