  1. 1. Perspectives on Biofilms for the Removal of Organic Micropollutants in Wastewater

    Författare :Ellen Edefell; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treatment; wastewater; biofilm; ozonation; activated carbon; powdered activated carbon; granular activated carbon; biological degradation; Moving bed biofilm reactor;

    Sammanfattning : The use of biofilms to improve the removal of organic micropollutants in waste¬water treatment plants (WWTPs) has been investigated. The work is divided into two parts. In the first part, the use of biofilms for the biological degradation of micro¬pollutants was investigated. LÄS MER

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

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    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

  4. 3. Exploring the role of granular activated carbon in drinking water production

    Författare :Malin Ullberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Safe and clean drinking water is recognised as a human right by the United Nations, but water sources world-wide are affected by the widespread use of synthetic chemicals, creating a challenge that drinking water producers must address. Many of these synthetic chemicals, here referred to as organic micropollutants (OMPs), are not well removed by conventional drinking water treatment, and thus additional treatment steps are needed.

  5. 4. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants

    Författare :Simon Gidstedt; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direkt membranfiltrering; Granulärt aktivt kol; Avloppsvatten; Kemisk förbehandling; Mikrosilning; Direct membrane filtration; Granular activated carbon; Wastewater; Chemically enhanced primary treatment; Microsieving;

    Sammanfattning : Pharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms.

  7. 5. From removal of organic micropollutants to municipal wastewater reuse - technological and social perspectives

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

    Sammanfattning : 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. LÄS MER
