  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. Analysis of Benzoisothiazolinone in process water from operations that handle large amounts of paint residues

    Master-uppsats, KTH/Kemi

    Författare :Cagenna Magendran; [2022]
    Nyckelord :Flocculation; Gas chromatography-mass spectrometry; Isothiazolinones; Paint residues; Stockholm s water and waste; Flockulering; Gaskromatografi-masspektrometri; Isotiazolinoner; Färg rester; Stockholm vatten och avfall.;

    Sammanfattning : I denna studie undersöks isotiazolinoner i avloppsvatten eftersom det finns i alla kommersiella färger. För att avgöra om reningsverken är tillräcklig bra används gaskromatografi-masspektrometri (GC-MS) för att analysera förekomsten av BIT i processvatten som släpps ut i mjövattnet. LÄS MER

  4. 3. Effects on wastewater due to new active pharmaceutical ingredients and products

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Marina Vik; [2019]
    Nyckelord :Pharmaceutical wastewater; wastewater treatments; BOD; COD; chemical engineering; kemiteknik; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Wastewater from pharmaceutical industries can sometimes contain substances that could cause complications in the receiving wastewater treatment plant. This master thesis is about a phar-maceutical company and the wastewater from it. LÄS MER

  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. Inhibition of Nitrification in Industrial Wastewater - Identification of Sources

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Vidar Aspelin; Jennifer Ekholm; [2017]
    Nyckelord :nitrite; nitrate; industrial wastewater; inhibition of nitrification; additivity; nitrifikationshämning; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : The discharge of industrial wastewaters (WWs) to wastewater treatment plants (WWTPs) can be problematic due to their sometimes elevated concentrations of toxic compounds compared to municipal wastewater. Also, industrial WWs often contain compounds that are unique to the specific production, and the receiving WWTP is not always designed to remove these compounds. LÄS MER
