    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. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

    Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Arve Heistad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small-scale; sand filter; phosphorus filter; package plant; blackwater; greywater; urine diversion; multi-criteria; composite sample; VA-teknik; Urban Water Engineering;

    Sammanfattning : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems. LÄS MER
