    Sammanfattning : Water constraints for humans and nature are gaining more and more public attention as a critical environmental dilemma that needs to be addressed. When aquifers and rivers are running dry, the debate refers to an ongoing “world water crisis”. LÄS MER

  3. 2. When water becomes a threat : Risk assessment and risk management plans for floods and drinking water in Swedish practice

    Författare :Viveca Norén; Kevin Bishop; Beatrice Hedelin; Lars Nyberg; Sven Halldin; Kurt Petersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flood; Drinking water supply; Risk management; Risk assessment; Flood risk management plan FRMP ; Integrated flood management IFM ; Tools and methods; Practice compared to theory; Sweden; Municipalities; Interview study; Document study; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Water is an essential but vulnerable resource. A shortage of good quality drinking water is a threat to human health and society as a whole. Abundance of water in the form of floods can also be a serious threat which can have consequences for the drinking water supply. To reduce these risks there is a need for systematic risk reduction.

  4. 3. Energisystemet är också en fråga om planutformning : teoretiska och empiriska studier av energisystemets rumsliga artefakter i fysisk planering

    Författare :Björn Ekelund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : Det svenska energisystemet är under omställning för att på sikt låta förnybar energi svara för hela energitillförseln. Med detta följer fler anläggningar och en större diversitet mellan olika energislag. Kommunernas roll i detta är uppenbar. LÄS MER

  5. 4. Biofiltration of odorous gas emissions

    Författare :Anneli Andersson-Chan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Biofiltration has shown its potential as an interesting treatment alternative for contaminated gas streams. Unlike conventional technologies, such as adsorption, scrubbers, and incineration, biofiltration offers effective pollution control at relatively low capital and operating costs, and without the generation of secondary pollution that may require subsequent treatment.

  7. 5. Analytics-driven approaches supporting asset management of sanitary sewer networks

    Författare :Emmanuel Okwori; Annelie Hedström; Maria Viklander; Marius Møller Rokstad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven; Decision Support; Network Robustness; VA-teknik; Urban Water Engineering;

    Sammanfattning : Sewer blockages can cause overflows and flooding, with consequences such as damage to property and environmental pollution, risks to public health and economic loss. Despite the causes being understood, blockages in sewer networks may occur unpredictably. LÄS MER
