  1. 21. 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. 22. Biological phosphorus removal from wastewater with a moving bed biofilm reactor process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Rebecca Arvidsson; [2015]
    Keywords : biological wastewater treatment; EBPR; MBBR; denitrifying phosphorus removal; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental engineering; Technology and Engineering;

    Abstract : The human population is increasing and more wastewater, rich in nutrients, is produced. Increased levels of nutrients such as phosphorus, nitrogen and organic matter in water bodies present a risk for eutrophication, toxicity to the water-living fauna and oxygen depletion. READ MORE

  4. 23. 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. 24. 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

  6. 25. 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
