    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Sammanfattning : There are about 700,000 on-site sewage facilities (OSSFs) in Sweden, almost a quarter of which amount only to septic tanks for sludge collection and removal, with no form of post-treatment. All these OSSFs contribute about 10 % of the total anthropogenic phosphorus (P) load from Swedish coasts to the Baltic Sea. LÄS MER

  3. 2. On-site sewage treatment facilities, unacceptable quality or too small to count? : cost-benefit analysis of on-site sewage treatment facilities and the zeroeutrophication target

    Kandidat-uppsats, SLU/Dept. of Economics

    Författare :Philip Gudinge; [2017]
    Nyckelord :cost-benefit analysis; eutrophication; The Swedish Environmental Code;

    Sammanfattning : Private on-site sewage treatment facilities are only a small part of the Baltic Sea eutrophication problem, but it have caught attention due to its high share of deposition of nitrogen and phosphorus in comparison to the more efficient public sewage treatment plants. The treatment of sewage wastewater is regulated by the Swedish Environmental Code. LÄS MER

    Sammanfattning : Today many households in Sweden use small on-site sewage facilities to take care of their own wastewater which is then treated and released into the environment. The sewage sludge that remains contain many nutrients, like phosphorous and nitrogen, which could potentially be reused as fertilizers. LÄS MER

  7. 5. Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

    Sammanfattning : Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies. LÄS MER
