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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; [2009]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Luleå : Luleå tekniska universitet

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

    Abstract : 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. READ MORE

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

    University dissertation from Umeå : Umeå University

    Author : Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Eva Dock; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; screen-printed electrode; multivariate data analysis; wastewater; Analytical chemistry; electronic tongue; biosensor array; amperometric;

    Abstract : 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

    University dissertation from Stockholm : KTH

    Author : Maja Dlugolecka; Elzbieta Plaza; Bengt Hultman; Nicklas Paxéus; [2007]
    Keywords : 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;

    Abstract : 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. READ MORE
