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

    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

  2. 2. Partial renewal of granular activated carbon filters for improved drinking water treatment

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Nashita Moona; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofiltration; Drinking water treatment; Spectroscopic properties; Granular activated carbon filter; Natural organic matter; Online monitoring; Fluorescence;

    Sammanfattning : Drinking water is widely collected from surface water sources. In these water sources, both the quantity and quality of natural organic matter (NOM) have been affected around the world during the last decades, especially in Northern Europe and North America. LÄS MER

  3. 3. Effects of Natural Organic Matter on Herbicide Adsorption to Activated Carbon

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Åsa Edell; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural organic matter; herbicide; adsorption isotherm; preloading; activated carbon; competitive interaction;

    Sammanfattning : The presence of pesticides in the aquatic environment represents a potential threat to water quality and human health. Increasingly stringent drinking water quality directives focus on the need for efficient pesticide removal processes. LÄS MER

  4. 4. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Detta är en avhandling från Stockholm : KTH

    Författare :Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur 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

  5. 5. Antimicrobials in sewage treatment plants occurrence, fate and resistance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER
