1. 6. Improvement of Wastewater Sludge Digestion

   Författare :Michael Recktenwald; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

   Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER

3. 7. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

   Författare :Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; Experimental investigations; Techno-economic; Wastewater; Flue gas condensate; Waste heat; District heating; Nano-electronics; Cogeneration; Sustainable development; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

   Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER

4. 8. Ozonation in Advanced Wastewater Treatment : Practical Aspects and Development of a Prediction Tool for Pharmaceutical Removal

   Författare :Rubén Juárez; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ozonation; wastewater; suspended solids; pharmaceuticals; bromate;

   Sammanfattning : Pharmaceuticals that are not completely metabolized in the human body are excreted in wastewater and may find their way into surface waters, where they can have harmful effects on aquatic fauna and flora. The implementation of ozonation at wastewater treatment plants (WWTPs) can reduce the amount of pharmaceuticals discharged to the environment. LÄS MER

5. 9. Degradation of organic matter in wastewater -Enhanced denitrification and removal of refractory organics

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

   Sammanfattning : 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. LÄS MER

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

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

   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.
