  1. 1. 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.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filamentous fungi; municipal wastewater; pharmaceutical substances; fungal fluidized bed pelleted bioreactor; nutrients; diclofenac; ketoprofen; Trametes versicolor; Aspergillus luchuensis; Filamentösa svampar; kommunalt avloppsvatten; läkemedelsrester; bioreaktor; näringsämnen; diklofenak; ketoprofen; Trametes versicolor; Aspergillus luchuensis; Mikroskopiskās sēnes; sadzīves notekūdeņi; farmaceitiskās vielas; mikroskopisko sēņu bioreaktors; diklofenaks; ketoprofens; Trametes versicolor; Aspergillus luchuensis; Bioteknologi; Biotechnology;

    Sammanfattning : The ever-increasing concern about the widespread occurrence of pharmaceutical substances in the aquatic environment has been recognized as an emerging environmental issue as it can cause undesirable effects on the ecosystem and human health. The current wastewater treatment methods are not designed to treat municipal wastewater from the contamination of various pharmaceutical substances. LÄS MER

  7. 5. Removal of organic micropollutantns from wastewater in a Swedish context

    Författare :Maja Ekblad; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater treament; ozone; ozonation; pharmaceutical residues; Organic micropollutants; driving forces; drivers; avloppsvattenrening; ozon; ozonering; läkemedelsrester; organiska mikroföroreningar; drivkrafter;

    Sammanfattning : Due to their potential environmental risk, the abatement of organic micropollutants from wastewater has gained increasing attention in recent years. This thesis evaluates the use of ozone in Swedish wastewater treatment plants (WWTPs) and the incentives for full-scale implementation of organic micropollutant removal. LÄS MER
