   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. Matter that matters : A study of household routines in a process of changing water and sanitation arrangements

   Författare :Helena Krantz; Jan-Olof Drangert; Elin Wihlborg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Urban water and sanitation arrangements; change; routines; everyday life; household management; water use; pocket of local order; matter out of place; comfort; cleanliness; convenience; sustainability; households; Miljöteknik; teknisk hygien; vatten och avlopp; Water in nature and society; Vatten i natur och samhälle;

   Sammanfattning : Our society changed, but the urban water and sanitation system of today is roughly the same as it was 100 years ago. The system is designed for, developed from and sustained by human activities, and has since its introduction affected household patterns of routine activities. LÄS MER

4. 3. 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.

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. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

   Författare :Lea Rastas Amofah; Helen French; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.
