  1. 11. Antimicrobials in sewage treatment plants occurrence, fate and resistance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Marcus Östman; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

  2. 12. STUDY OF BACTERIAL COMMUNITIES – A WASTEWATER TREATMENT PERSPECTIVE

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Adrian Rodriguez Caballero; Mälardalens högskola.; [2011]
    Nyckelord :Activated sludge; COD removal; Constructed wetland; DGGE; FISH; Molecular microbiology; Nitrification; PCR; Wastewater treatment.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In this thesis, the application of molecular microbiology methods to understand wastewater treatment bio-reactions is described. Two different wastewater treatment systems were chosen for the experimental work. LÄS MER

  3. 13. Monitoring Wastewater Treatment Systems

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Christian Rosén; Lunds universitet.; Lund University.; [1998]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work considers various techniques to extract information from the vast amount of data collected at a modern wastewater treatment plant. If the information extracted is to be considered reliable is highly dependent on the data screening. Data screening includes validation and quality improvement of data. LÄS MER

  4. 14. On-site wastewater treatment Polonite and other filter materials for removal of metals, nitrogen and phosphorus

    Detta är en avhandling från Stockholm : KTH

    Författare :Agnieszka Renman; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline materials; heavy metals; mechanisms; nutrient removal; sorption; speciation modelling; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Sammanfattning : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. LÄS MER

  5. 15. Indigenous microalgae-activated sludge cultivation system for wastewater treatment

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Anbarasan Anbalagan; Mälardalens högskola.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. LÄS MER
