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

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Emine Gülce Hepdarcan; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 7. 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. 8. N2O emission in a full-scale partial nitrification/anammox process.

    University essay from KTH/Mark- och vattenteknik

    Author : Alejandro Sambola; [2012]
    Keywords : GHG; Global Warming; nitrous oxide; deammonification; rejected water;

    Abstract : The reduction of the emission of greenhouse gases to the atmosphere will be one of the challenges that society will have to face in the coming years. Until now, all efforts have been put in improving the properties of the discharged water in a wastewater treatment plant and the efficiency of the whole process. READ MORE

  5. 9. Evaluation of Deammonification process operated at low temperatures.

    University essay from KTH/Mark- och vattenteknik

    Author : Mariusz Rajkowski; [2012]
    Keywords : Deammonification; Anammox; low temperatures; conductivity;

    Abstract : Anammox process is happening to be in the center of interest for several years. Implementing partial nitrification/Anammox process into main stream of wastewater would result in a great improvement of sustainable technologies for reducing nitrogen in environment. READ MORE

  6. 10. Study on one-stage Partial Nitritation-Anammox process in Moving Bed Biofilm Reactors: a sustainable nitrogen removal.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Andrea Bertino; [2011]
    Keywords : Anammox Biofilm; Deammonification; CANON; Moving Bed Biofilm Reactor; Re-ject water;

    Abstract : In the last decade, several novel and cost-effective biological nitrogen removal technologies have been developed. The discovery of anaerobic ammonium oxidation (Anammox), about 15 years ago, has resulted in new opportunities for research and development of sustainable nitrogen removal systems. READ MORE
