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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  3. 2. Sustainability assessment of urine concentration technologies

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Matilda Gunnarsson; [2021]
    Nyckelord :Wastewater treatment; urine concentration; alkaline dehydration; nitrification-distillation; ion-exchange; struvite precipitation; MCA; Avloppsvattenrening; urinkoncentrering; alkalisk urintorkning; nitrifikations-destillering; jonbyte; struvitfällning; MKA;

    Sammanfattning : The majority of the nutrients in household wastewater are found in the urine and in order to facilitate the use the nutrients in the urine as fertilizer, the urine can be can be concentrated. To extract the nutrients from the urine, various technologies for urine concentration are being developed today. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

    Master-uppsats, KTH/Vatten- och miljöteknik

    Författare :Alessio Robiglio; [2018]
    Nyckelord :Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

    Sammanfattning : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities.

  7. 5. Evaluation of the effect of different SCOD/TN ratios in a mainstream nitritation process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Doaa el Halabi; [2017]
    Nyckelord :Partial nitrification; nitritation; microscreen; filtration; Chemical oxygen demand; moving bed biofilm reactor; Partial nitrification anammox; PNA.; Technology and Engineering;

    Sammanfattning : Avloppsvatten är rikt på organiskt material, det organiska materialet har med fördel använts för biogasproduktion. Den traditionella kvävereningsprocessen kräver organiskt material, därför har ett extern organiskt material använts. LÄS MER
