  2. 21. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

    Author : Alexander Betsholtz; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

    Abstract : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. READ MORE

  4. 22. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications

    Author : Göran Samuelsson; Jonas Gunnarsson; Maria Granberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin layer capping; sediment remediation; activated carbon; contaminated sediment; benthic community; Systems Ecology; systemekologi;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

  5. 23. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Author : Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; Water engineering; Vattenteknik;

    Abstract : 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. READ MORE

  6. 24. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

    Author : Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Advanced wastewater treatment; WWTP; pilot plant; pharmaceutical residues; removal of pharmaceuticals; activated carbon; ozonation; nanofiltration; biomarker; Baltic Sea; Bioteknologi; Biotechnology;

    Abstract : Pharmaceutical residues are found in the environment due to extensive use in human and veterinary medicine. The active pharmaceutical ingredients (APIs) have a potential impact in non-target organisms. Municipal wastewater treatment plants (WWTPs) are not designed to remove APIs. READ MORE
