2. 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 : 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; 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).

4. 2. Flow-oriented studies for environmental management by local authorities : experiences from a regional substance flow analysis

   Author : Annica Lindqvist-Östblom; Linköpings universitet; []
   Keywords : flow-oriented studies; material flow analysis; substance flow analysis; interpretation; local authorities; regional authorities; environmental management; cadmium; sewage;

   Abstract : This thesis focuses on the issue of how to perform flow-oriented studies in order to become more useful for and adapted to local/regional authorities. Compared to traditional environmental monitoring and measurement of the state of the environment, flow-oriented studies are an attempt to broaden the approach to environmental concerns. READ MORE

5. 3. 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

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

   Author : Kristin Blum; Peter Haglund; Patrik Andersson; Pim Leonards; Umeå universitet; []
   Keywords : 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; analytisk kemi; Analytical Chemistry;

   Abstract : 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.

7. 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 : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sewage sludge management; techno-economic analysis; phosphorus recovery; thermochemical treatment; Energy Engineering; Energiteknik;

   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.
