  1. 11. Ozonation in Advanced Wastewater Treatment : Practical Aspects and Development of a Prediction Tool for Pharmaceutical Removal

    Författare :Rubén Juárez; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ozonation; wastewater; suspended solids; pharmaceuticals; bromate;

    Sammanfattning : Pharmaceuticals that are not completely metabolized in the human body are excreted in wastewater and may find their way into surface waters, where they can have harmful effects on aquatic fauna and flora. The implementation of ozonation at wastewater treatment plants (WWTPs) can reduce the amount of pharmaceuticals discharged to the environment. LÄS MER

  3. 12. Removal of Pharmaceuticals in Biofilm and Activated Sludge Systems

    Författare :Per Falås; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Abstract The present work investigates i) the occurrence and removal of pharmaceuticals at Swedish WWTPs, and ii) potential causes for differences in the removal efficiency of pharmaceuticals at wastewater treatment plants. Particular attention is directed at the biological treatment and the pharmaceutical removal capacity per unit biomass of activated sludges and carrier biofilms of different origins. LÄS MER

  4. 13. Application of ozone in wastewater treatment : Oxidation of pharmaceuticals and filamentous bulking sludge

    Författare :Filip Nilsson; Avdelningen för kemiteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous Sludge; Pharmaceuticals; Wastewater Treatment; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

    Sammanfattning : As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. LÄS MER

  5. 14. Neurobiological Consequences of Social Conditions and Alcohol Exposure in Adolescent rats

    Författare :Linnea Granholm; Ingrid Nylander; Anne-Lie Svensson; Erika Roman; Maria Ellgren; Uppsala universitet; []

    Sammanfattning : Adolescence represents a time of extensive reorganisation and maturation of brain circuits involved in emotions, motivation and cognition and it is a period particular sensitive for external stimuli. External stimuli can be both socio-environmental factors and exposure to exogenous compounds such as drugs of abuse (e.g. alcohol). LÄS MER

  7. 15. Application of chemical oxidation processes for the removal of pharmaceuticals in biologically treated wastewater

    Författare :Gerly Hey; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The discharge of effluents from wastewater treatment plants (WWTPs) is considered to be the major source of residual pharmaceuticals frequently found in aquatic environments. The complex nature of such compounds tends to make conventional biological treatments aimed at their removal ineffective. LÄS MER
