  1. 11. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

    Författare :Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER
