  1. 1. Influence of Wastewater DOM Fractions on the Adsorption of Pharmaceuticals onto Activated Carbon

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Koustubh Karande; [2022]
    Nyckelord :Wastewater treatment; Dissolved organic matter; Pharmaceuticals; Activated carbon; Hydrophobicity; Molecular weight; Water resources engineering; Technology and Engineering;

    Sammanfattning : Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. LÄS MER

  3. 2. Pulverkol som akut kemisk barriär för dricksvatten

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Alexandra Klerck; [2020]
    Nyckelord :Bensin; MGO; Hybridolja; Pulveriserat aktivt kol PAK ; oljeutsläpp; löslighet;

    Sammanfattning : På Norrvattens reningsverk, Görvälnverket, produceras dricksvatten genom rening av råvatten från Östra Mälaren. Dricksvattenverket ligger i direkt anslutning till Mälaren, vilket är bra då vattnet inte behöver transporteras för att renas. LÄS MER

  4. 3. Fluorescence probes: towards automatic coagulant dosing

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Daphné Lecellier; [2018]
    Nyckelord :Drinking water quality; Water treatment process; Coagulation; Microcystis aerugosa; algal organic matter; LC-OCD; EEM; powdered activated carbon; Alum;

    Sammanfattning : There is a current lack of accurate tools to determine the concentration of cyanobacteria in situ.  Besides, cyanobacterial blooms have to be carefully monitored in reservoirs as they are more frequent because of climate change and can lead to potential released of toxins, along with other components.

  5. 4. Möjligheten att kombinera pulveriserat aktivt kol (PAK) och MBBR för avskiljning av organiska mikroföroreningar

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sofia Högstrand; Maja Ignell; [2018]
    Nyckelord :PAK; pulveriserat aktivt kol; MBBR; Moving Bed Biofilm Reactor; avancerad rening; avloppsreningsverk; organiska mikroföroreningar; avloppsteknik; Technology and Engineering;

    Sammanfattning : The increased use of pharmaceuticals in combination with inadequate techniques and procedures in the wastewater treatment plants (WWTPs) have resulted in higher concentrations of pharmaceuticals and other organic micro pollutants (OMPs) in the aquatic environment. It has been established that these pollutants have caused changes in the behaviour and reproduction of fishes. LÄS MER

  7. 5. Integration of powdered activated carbon in tertiary disc filtration of wastewater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Elias Thörnqvist; Philip Isgaard; [2016]
    Nyckelord :vattenförsörjningsteknik; water engineering; environmental engineering; flocculation; coagulation; PAC; disc filter; micropollutants; powdered activated carbon; avloppsteknik; Technology and Engineering;

    Sammanfattning : This thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. LÄS MER
