  1. 1. Removal processes in sewage treatment plants Sludge quality and treatment efficiency of structurally diverse organic compounds

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Ulrika Olofsson; Umeå universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmetrics; flame retardants; GCxGC; non-targeted screening; mass flow; metals; plasticizers; poorly removed contaminants; POP; PPCP; prediction; Principal Component Analysis; removal efficiency; sewage; sewage treatment plants; sludge; sludge adsorption; sources; time-trend analysis; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : Large and ever-increasing numbers of chemicals, including large quantities of a broad spectrum of organic compounds are used in modern society. More than 30 000 of the more than 100 000 chemical substances registered in the EU are estimated to be daily used, of which many will be discharged into the waste-streams handled by municipal sewage treatment plants (STPs).

  2. 2. Tailoring residue-derived carbon materials for the removal of wastewater contaminants adsorption and surface properties

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Mirva Niinipuu; Umeå universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Sammanfattning : The availability of effective, low-cost wastewater treatment is necessary for increased water recycling and the prevention of environmental pollution on a global scale. Adsorption on activated carbons is commonly applied in wastewater treatment, but the high cost of conventional activated carbons limits the use of this technique. LÄS MER

  3. 3. Alternative Adsorption Materials for Treatment of Contaminated Waters

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Yuliya Kalmykova; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; Sphagnum peat; Heavy metals; Fiber ash;

    Sammanfattning : The thesis presents a study of adsorbent materials for treatment of contaminated waters and remediation of contaminated soils. Natural and waste product materials showed high adsorption capacity for metals and organic pollutants and proved to be a good alternative to commercial adsorbents. LÄS MER

  4. 4. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Joanna Wawrzynczyk; Lunds universitet.; Lund University.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

    Sammanfattning : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. LÄS MER

  5. 5. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Klas Arnerdal; KTH.; [2002]
    Nyckelord :Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

    Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.
