2. 6. Effects of ozonated sewage effluents and pharmaceuticals in zebrafish (Danio rerio)

   Author : Johannes Pohl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The aquatic environment is the main destination for many organic pollutants originating from human activity. Pharmaceuticals are significant contributors to this pollutant cocktail. READ MORE

4. 7. 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.

5. 8. External Growth Control of Baltic Sea Cyanobacteria

   Author : Anna Zakrisson; Ulf Larsson; Jakob Walve; Elena Gorokhova; Sanna Suikkanen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; cyanobacteria; nitrogen fixation; heterocysts; Aphanizomenon; Nodularia; water treatment; Himmerfjärden; sewage; climate; Marine Ecology; marin ekologi;

   Abstract : In the Himmerfjärden Bay a large excess of nitrogen over phosphorus in the discharge from a large sewage treatment plant (STP) has suppressed growth of diazotrophic cyanobacteria in its inner parts. Implementation of nitrogen removal in the STP in 1997 drastically reduced nitrogen load and triggered growth of diazotrophs, mainly Aphanizomenon sp. READ MORE

6. 9. 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 : 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

7. 10. 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.
