  1. 11. A study of pharmaceutical residues in wastewater from small municipalities in Northern Sweden : E-peroxone as a complementary tertiary removal technique

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Mathias Hägglund; [2021]
    Keywords : Pharmaceuticals; removal; sewage treatment plants STPs ; Electro-peroxone E-peroxone ;

    Abstract : The conventional treatment processes used in Swedish sewage treatment plants (STPs) are not designed to remove micropollutants such as pharmaceuticals and biocides. This leads to STPs being a major source of pharmaceuticals in the environment including surface waters, coastal waters, and groundwaters all over the world. READ MORE

  2. 12. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Ekman; [2021]
    Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

    Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.

  3. 13. Comparison of mesophilic and thermophilic anaerobic sludge digestion at Hammarby Sjöstadsverk MBR pilot plant for wastewater treatment

    University essay from SLU/Department of Molecular Sciences

    Author : Jessica Sellin; [2021]
    Keywords : Anaerobic digestion; sludge; wastewater treatment; thermophilic; mesophilic; stress test;

    Abstract : Anaerobic digestion is a commonly used method for stabilisation of sewage sludge and production of biogas at municipal wastewater treatment plants (WWTPs). The hydraulic retention time for sludge in the digestion reactors is about 16 days at Henriksdal WWTP in Stockholm. READ MORE

  4. 14. POLYAROMATIC HYDROCARBONS IN HYDROCHARS : HYDROTHERMAL CARBONIZATION OF SEWAGE SLUDGE

    University essay from Umeå universitet/Kemiska institutionen

    Author : Björn Sundqvist; [2021]
    Keywords : ;

    Abstract : Sewage sludge is an inevitable by-product from waste water treatment plants. Sludgemanagement is a difficult task since sludge has a high moisture content, poordewaterability and generally contain heavy metals, pharmaceutical residues,polyfluorinated alkyl substances (PFAS) and organic pollutants.

  5. 15. Assessment of zebrafish embryo toxicity of environmentally relevant antibiotics

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Ophelia Mastrangeli; [2021]
    Keywords : zebrafish embryo; toxicity; antibiotics; FET; Fish embryo toxicity; Bioaccumulation; zebrafiskembryo; toxicitet; antibiotika; FET; Bioackumulering;

    Abstract : Antibiotics are essential drugs in modern medicine. After consumption antibiotics are excreted in unmetabolized form in the urine and reach our sewage treatment plants (STP). STP are not able to degrade all antibiotics leading to release of antibiotics into the aquatic environment. Aquatic animals are thus continuously exposed to antibiotics. READ MORE
