  1. 1. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

    Författare :David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

    Sammanfattning : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

    Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER

  4. 3. Assessing and optimizing biofilter performance in drinking water treatment

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

    Sammanfattning : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. LÄS MER

  5. 4. PFAS in the water supply: source water contamination

    Författare :Dauren Mussabek; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source water; drinking water; per- and polyfluoroalkyl substances; PFAS; AFFF; UV treatment;

    Sammanfattning : Water contamination with per- and polyfluoroalkyl substances (PFAS) is a serious problem for water suppliers in many regions. Due to persistence of the substances and a complex distribution mechanism, PFAS can have an adverse impact on water quality. LÄS MER

  7. 5. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools

    Författare :Elin Lavonen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. LÄS MER
