  2. 16. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Author : Mathieu Le Noir; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Abstract : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. READ MORE

  4. 17. Inhibition of Nitrification in Municipal Wastewater - Sources, Effects, Evaluation and Remedies

    Author : Karin Jönsson; Vattenförsörjnings- och avloppsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Wastewater; Toxicity; Nitrification; Inhibition; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. READ MORE

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

    Author : Mirva Niinipuu; Stina Jansson; Jean-Francois Boily; Erik Rosenbaum; Magnus Bergknut; Capucine Dupont; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Adsorption; hydrochar; HTC; chemical activation; wastewater; pharmaceuticals; metals; surface properties; biobased residues;

    Abstract : 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. READ MORE

  6. 19. The role of wastewater in surveillance and emergence of antibiotic resistant bacteria

    Author : Marion Hutinel; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Bacteriology; Antibiotic resistance; Surveillance; Horizontal gene transfer; HGT; Conjugation; Plasmids; Epidemiology; CPE; E. coli; Carbapenamase; Linezolid; Colistin; Selection; sul4; OXA-48; gar; NDM; mcr; wastewater; sewage; sewer;

    Abstract : As antibiotic resistance spreads among bacterial pathogens, it reduces treatment options and increases treatment failures of infectious diseases. Strategies employed to reduce this spread or adapt to its consequences need to be based on reliable surveillance data which is lacking in many countries, often due to limited resources. READ MORE

  7. 20. Degradation of organic matter in wastewater -Enhanced denitrification and removal of refractory organics

    Author : Marinette Hagman; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; leachate; denitrification; carbon source; advanced oxidation; Activated sludge; wastewater; oxygen uptake rate; ozone;

    Abstract : Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. READ MORE
