  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

  3. 2. 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
