  1. 1. Microsieving in municipal wastewater treatment : Chemically enhanced primary and tertiary treatment

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Janne Väänänen; [2017-02-02]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coagulation; wastewater treatment; flocculation; microsieving; control; primary treatment; tertiary treatment; coagulation; control; flocculation; microsieving; municipal wastewater treatment; primary treatment; tertiary treatment;

    Sammanfattning : Municipal wastewater treatment plants are constantly forced to make improvements. The main objectives are to reduce energy consumption, to increase the treatment capacity and to improve the effluent water quality. Microsieves in combination with chemical pretreatment can potentially fulfil these objectives. LÄS MER

  2. 2. Municipal wastewater treatment by microsieving, microfiltration and forward osmosis : Concepts and potentials

    Sammanfattning : Conventional wastewater treatment plants are designed for treating manmade wastewater (e.g., from households and industries) and to protect the environment (e.g. LÄS MER

  3. 3. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Biotechnology; Bioteknologi;

    Sammanfattning : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. LÄS MER

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

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; [2017]
    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

  5. 5. Antibiotic Resistance in Wastewater Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER
