    Detta är en avhandling från Venice : Università Ca’ Foscari di Venezia

    Författare :Sabine Ferneborg; Sveriges lantbruksuniversitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Milk from dairy cows is a staple dietary component for humans all over the world. Regardless of whether milk is consumed in its purest, unaltered form or as high-end products such as fine cheese or ice cream, it needs to be of high quality when taken from the cow, produced at a low price and produced in a system that consider aspects such as animal health, animal welfare and sustainability.

    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).

  4. 4. Targeted and untargeted analysis of organic contaminants from on-site sewage treatment facilities Removal, fate and environmental impact

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Kristin Blum; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; decentralized sewage treatment; wastewater; surface water; environmental fate; bioavailability; removal efficiency; mass fluxes; biochar; environment; GC×GC-MS; LC-IM-MS; mass spectrometry; contaminants; pollutants; prioritization; non-target analysis; screening; Analytical Chemistry; analytisk kemi;

    Sammanfattning : On-site sewage treatment facilities (OSSFs) are widely used all over the world to treat wastewater when large-scale sewage treatment plants (STPs) are not economically feasible. Although there is great awareness that the release of untreated wastewater into the environment can lead to water-related diseases and eutrophication, little is known about organic contaminants and their removal by OSSFs, environmental load and fate.

  5. 5. Coagulation process characteristics and pollutant removal from urban runoff

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Fredrik Nyström; Luleå tekniska universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stormwater; urban snowmelt; road runoff; coagulation flocculation sedimentation; coagulation characteristics; coagulation mechanism; treatment efficiency; VA-teknik; Urban Water Engineering;

    Sammanfattning : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies.  The treatment function of  SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles.
