  2. 1. Applications of natural organic matter optical properties for assessing drinking water disinfection and distribution

    Author : Masoumeh Heibati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; assimilable organic carbon.; Optical properties; disinfection by-products; drinking water; UV disinfection; dissolved organic matter; distribution network;

    Abstract : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants a nd within distribution networks. READ MORE

  5. 3. Titanium Dioxide Photocatalysis in Biomaterials Applications

    Author : Yanling Cai; Ken Welch; Maria Strømme; Håkan Engqvist; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; titanium dioxide; photocatalysis; bioactivity; antibacterial effect; metabolic activity assay; biofilm; reactive oxygen species; disinfection kinetics; post-UV;

    Abstract : Despite extensive preventative efforts, the problem of controlling infections associated with biomedical materials persists. Bacteria tend to colonize on biocompatible materials and form biofilms; thus, novel biomaterials with antibacterial properties are of great interest. READ MORE

  6. 4. From removal of organic micropollutants to municipal wastewater reuse - technological and social perspectives

    Author : Maria Takman; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater reuse; Water reclamation; Organic micropollutants; Granular activated carbon; UV disinfection; Discourses;

    Abstract : In this thesis, wastewater reuse was investigated from technological and social perspectives, based onwhich the thesis was divided into two parts. In the first part, the removal of chemical and microbialcontaminants by full-scale and pilot-scale granular activated carbon (GAC) filters, in different processcombinations, was examined. READ MORE

  7. 5. Safe drinking water in a changing environment : Membrane filtration in a Swedish context

    Author : ANGELICA LIDÉN; Avdelningen för Teknisk vattenresurslära; []
    Keywords : Boreal lakes; Drinking water; Nanofiltration; Natural organic matter; Ultrafiltration;

    Abstract : Surface water is vital for Swedish drinking water supply. In the past decades, a trend of increased total organic carbon (TOC) concentrations has led to higher consumption of coagulants in drinking water treatment, and has pushed the levels in the outgoing water closer to the allowed levels of TOC.
