  3. 2. Environmental Systems Analysis of Wastewater Management

    Författare :Erik Kärrman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The history of wastewater management tells us that efforts have been made at solving only one problem at the time; sanitation during the first half of the 20th Century followed by eutrophication of lakes and sea and, for the past ten years, recycling of nutrients. After the "Brundtland Report", 1987, a reversal of the debate occurred where water management was discussed in a more holistic manner than before. LÄS MER

  4. 3. 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.

  5. 4. Sustainable phosphorus removal in onsite wastewater treatment

    Författare :David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Paul Withers; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Onsite wastewater treatment; Soil treatment system; Phosphorus; Removal mechanisms; Environmental impacts; Life cycle assessment;

    Sammanfattning : Aquatic eutrophication is a serious environmental problem that occurs all over the world. To protect surface waters (in particular the Baltic Sea), the regulatory pressure on onsite wastewater treatment (OWT) systems have increased in Sweden. LÄS MER

  7. 5. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions

    Författare :Susanna Olsson; Jon Petter Gustafsson; Dan Berggren; Erik Kärrman; Bo Bergbäck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; Environmental chemistry; Miljökemi;

    Sammanfattning : There are several incentives for using bottom ash from municipal solid waste incineration (MSWI bottom ash) as a construction material, such as for road construction. These incentives include decreased disposal of material on landfills and a reduced amount of raw material extracted for road building purposes. LÄS MER
