  1. 1. Performance and control of biofilm systems with partial nitritation and Anammox for supernatant treatment

    Författare :Beata Szatkowska; Elzbieta Plaza; Bengt Hultman; Peter Balmér; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkalinity; Anammox; conductivity; partial nitritation; pH; removal rate; supernatant; Environmental engineering; Miljöteknik;

    Sammanfattning : Separate treatment of supernatant with dewatering of digested sludge with application of partial nitritation/Anammox process is assessed to be a cost-effective way to remove about 10-15% of influent nitrogen and, thereby, facilitate possibilities to reach required effluent requirements from the plant. The combined partial nitritation/Anammox process can be performed in two separate reactors or in one-stage. LÄS MER

  3. 2. Assessment of a partial nitritation/Anammox system for nitrogen removal

    Författare :Luiza Gut; Elzbieta Plaza; Joanna Surmacz-Gorska; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofilm; Deammonification; Nitrogen removal; Oxygen Uptake Rate OUR ; Partial nitritation Anammox system; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This thesis evaluates the performance of a deammonification system designed as a two-step tech-nology consisting of an initial partial nitritation followed by an Anammox process. Operation of a technical-scale pilot plant at the Himmerfjärden Wastewater Treatment Plant (Grödinge, Swe-den) has been assessed. LÄS MER

  4. 3. Microbial communities in anammox and nitrifying biofilms

    Författare :Carolina Suarez; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biofilms; AOB; partial nitritation anammox; nitrification; wastewater;

    Sammanfattning : Excess of nitrogen in water bodies causes eutrophication. One important source of nitrogen is the effluent from wastewater treatment plants (WWTPs). Nitrogen in wastewater is most commonly removed by nitrification-denitrification. LÄS MER

  5. 4. Treatment of ammoniuim-rich wastewater by partial nitritation/anammox in a biofilm system

    Författare :Beata Szatkowska; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Sammanfattning : .... LÄS MER

  7. 5. Comparative study on different Anammox systems

    Författare :Grzegorz Cema; Elżbieta Płaza; Joanna Surmacz-Górska; Karl-Heinz Rosenwinkel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anammox; biofilm system; landfill leachate; nitrogen removal; reject water; removal rates; Environmental engineering; Miljöteknik;

    Sammanfattning : The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements’ removal, in comparison with the past. LÄS MER
