  1. 1. Hur hanteras algblomning i dricksvattentäkt – en undersökning av algblomning i Bondsjön, Härnösands kommun, och förslag till åtgärder

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Johanna Sjölund; [2019]
    Nyckelord :algblomning; cyanobakterier; cyanotoxin; vattenrening; aktivt kolfilter; membranfilter;

    Sammanfattning : Algal blooms are a common phenomenon in lakes and seas in and around Sweden and poses a problem when found in a drinking water source. Some cyanobacteria can produce toxins which can be with a health problem. To get a safe drinking water it is necessary to be able to remove the toxins from the incoming water. LÄS MER

  2. 2. Evaluation of sustainability criteria for small-scale wastewater treatment facilities

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Edvard Nordenskjöld; [2017]
    Nyckelord :On-site sewage facilities; phosphorus; micropollutants; multi-criteria analysis; precipitation; adsorption; full-scale; wastewater treatment; Enskilda avlopp; fosfor; mikroföroreningar; multi-kriterie analys; utfällning; adsorption; fullskala; avloppsrening;

    Sammanfattning : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. LÄS MER

  3. 3. Evaluation of the Removal Efficiency of Perfluoroalkyl Substances in Drinking Water

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sophie Englund; [2015]
    Nyckelord :per- and polyfluoroalkyl substances; PFASs; anion exchange; activated carbon; drinking water; removal efficiency;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are chemicals that have been used for over 50 years. They are both hydrophobic and hydrophilic, which make them useful in a wide range of products, both in the domestic and industrial market. Recently, the global attention on PFASs has increased due to their possible harmful health effects on humans. LÄS MER

  4. 4. From source to tap : a case study of organic contaminants in raw and drinking water in the region of Uppsala, Sweden

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Philipp Klöckner; [2015]
    Nyckelord :drinking water; water quality; raw water; water contamination; from source to tap; water treatment; persistent pollutants; pharmaceuticals; pesticides; surface water; screening; Sweden; Lake Ekoln; Lake Mälaren; SPE; LC-MS; PPCP;

    Sammanfattning : In this study, water samples from the surroundings of Uppsala were examined for residues of pesticides, pharmaceuticals and other contaminants characteristic for human fecal contamination. The aim was to perform a screening of water samples to investigate the level of pollution with the mentioned compound groups. LÄS MER

  5. 5. Evaluation of the Removal Efficiency of Per- and Polyfluoroalkyl Substances in Drinking Water using Nanofiltration Membranes, Active Carbon and Anion Exchange

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Klara Lindegren; [2015]
    Nyckelord :PFASs; perfluoroalkyl substances; removal efficiency; NF; nanofiltration; membrane; GAC; granular activated carbon; AE; anion exchange; PFAS; perfluorerade alkylsubstanser; reningseffektivitet; NF; nanofiltrering; membran; GAC; granulärt aktivt kol; AE; jonbytarmassa;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) is a group of man-made, highly persistent chemicals. Due to the specific surface-active attributes of these molecules, applications are numerous and feed an economically important industry. During the last decade, PFASs have been detected globally in the environment, living organisms and tap water. LÄS MER
