  1. 1. Heterogeneous TiO2 Photocatalysis : Fundamental Chemical Aspects and Effects of Solid Phase Alterations

    Author : Veronica Diesen; Mats Jonsson; Hynd Remita; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Heterogeneous photocatalysis on TiO2 is an emerging green technology for water disinfection. The rationale for this technology is based on in-situ generation of highly reactive transitory species for degradation of organic and inorganic pollutants as well as microorganisms. READ MORE

  2. 2. Multifunctional Polymer Materials: From Synthesis to Disinfection

    Author : Haiyue Gong; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymer; Antibacterial; Ag nanoparticles; Antibiotic; Boronic acid; Polyethylenimine; Quaternary ammonium;

    Abstract : Polymer materials have wide applications in many industries, such as the food, pharmacy, construction, textile, and cosmetics industries. For the past few years, polymer materials have drawn the attention of scientists and engineers as a good disinfectant due to their advanced manufacturing methods, large surface areas, good stability, and lowcost.

  3. 3. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools

    Author : Elin Lavonen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY;

    Abstract : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. READ MORE

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

    Author : Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; 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

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

    Author : Masoumeh Heibati; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; 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
