  2. 16. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

    Author : Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

    Abstract : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. READ MORE

  4. 17. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

    Author : Ramnath Lakshmanan; Gunaratna Kuttuva Rajarao; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

    Abstract : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. READ MORE

  5. 18. Coagulant Protein from plant materials: Potential Water Treatment Agent

    Author : Ida Bodlund; Gunaratna Kuttuva Rajarao; Anna Norström; Andres Veide; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antimicrobial effect; Brassica; coagulant protein; MO2.1; Moringa oleifera; Mustard; napin; thermo-resistance; plant material; protein extraction; salt extract.;

    Abstract : Access to fresh water is a human right, yet more than 780 million people, especially in rural areas, rely on unimproved sources and the need for finding ways of treating water is crucial. Although the use of natural coagulant protein in drinking water treatment has been discussed for a long time, the method is still not in practice, probably due to availability of material and limited knowledge.

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

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

    Abstract : 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. READ MORE

  7. 20. Environmental impact of peat mining : Development of storm water treatment methods

    Author : Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. READ MORE
