  1. 21. 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. 22. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Linnea Georgii; [2021]
    Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.

  4. 23. Carbon Filters for Drinking Water Treatment – How Flow Rate and Empty Bed Contact Time Influence the Performance

    University essay from KTH/Kemiteknik

    Author : Wilma Bäckström Nilsson; [2021]
    Keywords : Carbon filter; GAC; BAC; Biofilm; Flow rate; NOM; EBCT; Kolfilter; GAC; PAC; biofilm; flödeshastighet; NOM; uppehållstid;

    Abstract : Dricksvatten är en essentiell del av ett hållbart samhälle. Därför är det viktigt att säkerställa säkert dricksvatten genom fungerande vattenreningsverk. En viktig förorening att behandla är NOM, som i sig är ofarligt men som kan producera farliga föroreningar. En teknik som används för behandling av NOM är kolfiltrering. READ MORE

  5. 24. Edible Fungal Production using Acetic Acid as Carbon and Energy Source

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Barbara Mae Alontaga; Anna Axebrink; [2020]
    Keywords : VFA; Volatile fatty acid; acetic acid; Fungi; Carbon source; Energy source;

    Abstract : Volatile fatty acids (VFAs) have become attractive and gained high research interest due to its significance for the chemical industry and economical advantage. These acids can be produced by utilizing organic waste such as food waste as substrate through anaerobic digestion. READ MORE

  6. 25. Using bioaugmentation to enhance the denitrification process in a treatment plant for landfill leachate

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Oscar Skirfors; [2020]
    Keywords : Bioaugmentation; Landfill leachate; Wastewater treatment; Biological nitrogen removal; Denitrification; Waste management; Bioaugmentation; Deponilakvatten; Vattenrening; Biologisk kväverening; Denitrification; Avfallshantering;

    Abstract : It has been illegal to deposit household waste in Swedish landfills since 2005. The large amount of waste deposited prior to this does however continue to pose an environmental concern, mainly in the form of leachate water. This study focused on enhancing the denitrification process in a leachate water treatment plant through bioaugmentation. READ MORE
