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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Ulrika Olofsson; Umeå universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Sammanfattning : 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. Anaerobic digestion in the kraft pulp and paper industry Challenges and possibilities for implementation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Eva-Maria Ekstrand; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp and paper; anaerobic digestion; fibre sludge; activated sludge; condensates; bleaching wastewater; wastewater treatment; methane; degradability; nutrient recirculation; Pappers- och massa; anaerob nedbrytning; fiberslam; aktivt slam; kondensat; vattenrening; metan; nedbrytbarhet; näringsåterföring;

    Sammanfattning : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

  3. 3. Microbial Ecology of Granular Sludge

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Raquel Liebana; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

    Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER

  4. 4. 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
