  1. 1. 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

  3. 2. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Författare :Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; Water engineering; Vattenteknik;

    Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER

  4. 3. 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

  5. 4. Removal of Natural Organic Matter and Control of Trihalomethanes Formation in Water Treatment

    Författare :Herbert Mpagi Kalibbala; Elzbieta Plaza; Olle Wahlberg; Rose Kaggwa; Stein Wold Osterhus; KTH; []
    Nyckelord :Water treatment; pumice; roughing filtration; trihalomethanes; coagulant aid; volcanic ash; Vattenrening; pimpsten; grovfiltrering; trihalometaner; koaguleringsmedel; vulkanaska;

    Sammanfattning : Volcanic ash, pumice and Moringa oleifera (M. oleifera) were investigated as indigenous materials for removal of natural organic matter (NOM) at Kampala and Masaka water treatment plants in Uganda. LÄS MER

  7. 5. 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.
