  1. 1. Pilot scale partial denitratation coupled anammox: an evaluation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Tobias Ellingsen; [2022]
    Keywords : mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Abstract : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. READ MORE

  3. 2. Spatial and temporal changes in microbial community composition in a full-scale woodchip bioreactor for treating mine water

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Felicia Wallnäs; [2020]
    Keywords : ;

    Abstract : Incomplete detonation of nitrogen-based explosives can lead to abundant levels of nitrate in mine groundwater. The possibility of reducing nitrogen levels from the wastewater through denitrification, anammox and DNRA has been investigated using a full-scale bioreactor. The bioreactor is situated subsurface and is filled with pine woodchips. READ MORE

  4. 3. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.

  5. 4. Mainstream Deammonification process monitoring by bacterial activity tests

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andrea Carranza Muñoz; [2020]
    Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

  6. 5. Anammox in IFAS reactor for reject water treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Bingquan Chen; [2019]
    Keywords : Deammonification; IFAS; Online sensors; Partial nitritation Anammox; Reject water; Specific anammox activity;

    Abstract : The aim of this study was to evaluate the performance of the integrated fixed-film activated sludge (IFAS) reactor achieving partial nitritation/anammox process to treat reject water after dewatering of digested sludge. During the study period, dissolved oxygen setpoint, aeration mode and inflow loading were changed to evaluate their influence on the process performance and efficiency in the reactor. READ MORE
