   Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   Sammanfattning : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. LÄS MER

3. 2. 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.

4. 3. Comparative study on different Anammox systems

   Författare :Grzegorz Cema; Elżbieta Płaza; Joanna Surmacz-Górska; Karl-Heinz Rosenwinkel; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anammox; biofilm system; landfill leachate; nitrogen removal; reject water; removal rates; Environmental engineering; Miljöteknik;

   Sammanfattning : The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements’ removal, in comparison with the past. LÄS MER

5. 4. Controlling and monitoring of deammonification process in moving bed biofilm reactor

   Författare :Jingjing Yang; Elzbieta Plaza; Britt-Marie Wilén; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : It is considered that partial nitrification combined with anammox, named deammonification, is more environmental friendly compared with conventional nitrification/denitrification due to decrease energy requirement, low emission of CO2 and N2O. Dissolved oxygen (DO) is a significant parameter influencing the nitrogen removal rate and activity of different microorganisms. LÄS MER

7. 5. Constructing a Pipe-Bound City : A History of Water Supply, Sewerage, and Excreta Removal in Norrköping and Linköping, Sweden, 1860-1910

   Författare :Jonas Hallström; Jan-Olof Drangert; Marie C. Nelson; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; water supply; sewerage; waste disposal; actor-network theory; urban history; environmental history; history of technology; history of public health; vatten och avlopp; vattenförsörjning; avfallshantering; hitstoria; Sverige; History; Historia;

   Sammanfattning : In the mid- to late 19th century, modern pipe-bound water and sewer systems proliferated in European cities, a development that has sometimes been regarded as a necessary result of a sanitary awakening and the progress of science and technology. By analyzing the introduction and subsequent expansion of water, sewerage, and excreta collection on the local level, in the Swedish cities Norrköping and Linköping, this oversimplified picture is questioned.
