  4. 8. Hazardous substances in wastewater management

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

    Sammanfattning : The extensive use of materials and substances in society causes diffuse source emissions that lead to uncontrolled spreading of hazardous substances, largely channelled via wastewater systems, to the surrounding nature. Complex mixtures of substances appear in wastewater as a result of use, wear, and corrosion of goods (e.g. LÄS MER

  5. 9. 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.
