  1. 11. 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

  3. 12. 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%.

  4. 13. Factors increasing efficiency of deammonification process for nitrogen removal from mainstream wastewater.

    University essay from KTH/Mark- och vattenteknik

    Author : Aleksandra Wur; [2014]
    Keywords : partial nitritation Anammox process; lab-scale reactors; batch;

    Abstract : 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. READ MORE

  5. 14. Manometric method for evaluation of anammox activity in mainstream anammox at Sjölunda WWTP

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Dóra Stefansdottir; [2014]
    Keywords : Activity test; anammox: mainstream; MBBR; temperature dependency; vattenförsörjnings- och avloppsteknik; Chemistry;

    Abstract : Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity (SAA) was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. READ MORE
