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

    Author : Ulrika Olofsson; Peter Haglund; Staffan Lundstedt; Juliane Hollender; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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; Environmental chemistry; Miljökemi;

    Abstract : 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. Antimicrobials in sewage treatment plants : occurrence, fate and resistance

    Author : Marcus Östman; Mats Tysklind; Jerker Fick; Erik Björn; Klaus Kümmerer; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

  3. 3. Co-digestion of microalgae and sewage sludge - A feasibility study for municipal wastewater treatment plants

    Author : Jesper Olsson; Eva Thorin; Sebastian Schwede; Emma Nehrenheim; Raúl Muñoz Torre; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Anaerobic digestion; dewaterability; BMP-experiments; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The increased emissions of anthropogenic greenhouse gases over the last 100 years is the reason for the acceleration in the greenhouse effect, which has led to an increase of the globally averaged combined land and ocean surface temperature of 0.85 °C between 1880 and 2012.

  4. 4. Determination of Antibiotics in the Swedish Environment with Emphasis on Sewage Treatment Plants

    Author : Richard Lindberg; Barbro Andersson; Mats Tysklind; Magnus Johansson; Alfredo Alder; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; antibiotics; environment; sewage treatment plants; antibiotika; miljö; avloppsreningsverk; Environmental chemistry; Miljökemi;

    Abstract : Metoder har utvecklats för att kunna bestämma tolv antibiotikasubstanser, vanliga inom human medicin, i miljöprover. Fokus lades på trimetoprim samt substanser från följande grupper: fluorokinoloner, sulfonamider, penicilliner, cefalosporiner, nitroimidazoler, tetracykliner samt makrolider. READ MORE

  5. 5. Integrated sewage sludge treatment scenarios – techno-economic analysis on energy and phosphorus recovery

    Author : Marzieh Bagheri; Elisabeth Wetterlund; Marcus Öhman; Lale Andreas; Roozbeh Feiz; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sewage sludge management; techno-economic analysis; phosphorus recovery; thermochemical treatment; Energiteknik; Energy Engineering;

    Abstract : Sewage sludge is a by-product of wastewater treatment that simultaneously gathers contaminants, valuable organic matter, and nutrients. The treatment of the increasing amount of sewage sludge is important from both pollution prevention and resource recovery perspectives as i) large shares of mineral phosphorus, listed as a critical raw material, terminate in the sewage sludge, and ii) energy recovery from sewage sludge can cover the energy-intensive demand of the treatment process.
