  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. Ammonium removal from municipal wastewater with application of ion exchange and partial nitritation/Anammox process

    Författare :Andriy Malovanyy; Elzbieta Plaza; Andrei Zagorodni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater; nitrogen removal; ion exchange; nitritation; Anammox;

    Sammanfattning : Nitrogen removal from municipal wastewater with application of Anammox process offers cost reduction, especially if it is combined with maximal use of organic content of wastewater for biogas production. In this study a new technology is proposed, which is based on ammonium concentration from municipal wastewater by ion exchange followed by biological removal of ammonium from the concentrated stream by partial nitritation/Anammox process.
