  1. 1. Antibiotic Resistance in Wastewater Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Stefan Börjesson; Linköpings universitet.; Linköpings universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER

  2. 2. Hazardous substances in wastewater systems a delicate issue for wastewater management

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Helena Palmquist; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Many substances derived from human activity end up in wastewater systems at some point. A large number of different substances - up to 30,000 - are present in wastewater. Some of them are valuable, such as nitrogen and phosphorus, but there are also hazardous substances such as heavy metals and anthropogenic organic substances. LÄS MER

  3. 3. Wastewater treatment and biomass generation by Nordic microalgae growth in subarctic climate and microbial interactions

    Detta är en avhandling från Umeå : Umeå University

    Författare :Lorenza Ferro; Umeå universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

    Sammanfattning : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. LÄS MER

  4. 4. Development of a Bioelectronic Tongue -Applications for Wastewater Analysis

    Detta är en avhandling från Department of Analytical Chemistry, Lund University

    Författare :Eva Dock; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; screen-printed electrode; multivariate data analysis; wastewater; Analytical chemistry; electronic tongue; biosensor array; amperometric;

    Sammanfattning : A bioelectronic tongue has been developed for applications in wastewater analysis. The development of a biosensor array with complex signal analysis started from the idea of using group-selective phenol biosensors (tyrosinase and horseradish peroxidase) with chemometric analysis for signal processing.

  5. 5. Pharmaceutical compounds; a new challenge for wastewater treatment plants

    Detta är en avhandling från Stockholm : KTH

    Författare :Maja Dlugolecka; KTH.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; biodegradation; granular activated carbon GAC ; membrane bioreactor MBR ; pharmaceutical compounds; wastewater; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER
