1. 11. Pharmaceuticals – improved removal from municipal wastewater and their occurrence in the Baltic Sea

   Författare :Berndt Björlenius; Gen Larsson; Antonius J. A. van Maris; Hallvard Ødegaard; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 12. 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

4. 13. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

   Författare :Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

   Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

5. 14. The influence of soil and contaminant properties on the efficiency of physical and chemical soil remediation methods

   Författare :Sofia Jonsson; Mats Tysklind; Peter Haglund; Staffan Lundstedt; Tuula Tuhkanen; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fenton’s reagent; ozone; solvent washing; granular activated carbon; GAC; Persistent organic compounds; Persistenta organiska föreningar; Cardiology; kardiologi;

   Sammanfattning :  A vast number of sites that have been contaminated by industrial activities have been identified worldwide. Many such sites now pose serious risks to humans and the environment. Given the large number of contaminated sites there is a great need for efficient, cost-effective  remediation methods. LÄS MER

7. 15. Removal of Organic Micropollutants from Wastewater in Biofilm Systems

   Författare :Cecilia Burzio; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pharmaceuticals; Organic Micropollutants; Biological Treatment; Sorption; Aerobic Granular Sludge;

   Sammanfattning : The presence of organic hazardous substances in the aquatic environment, such as pharmaceutically active compounds and personal care products, has become a worldwide issue of increasing environmental concern. Present at concentration of nano- to milligram per liter, they are defined as organic micropollutants (OMPs). LÄS MER
