  1. 21. Nutrient concentrations before and after the Focus on Phosphorus project in E23 catchment

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Åsa Larsson; [2018]
    Nyckelord :phosphorus; Greppa fosforn; two-stage ditch; structure liming; sedimentation pond;

    Sammanfattning : Between 2007-2014, as part of the Greppa Näringen, there was a subproject on phosphorus losses called Focus on Phosphorus (FoP; Greppa Fosforn). Previous measures on eutrophication mainly focused on nitrogen leakage, whilst the purpose of FoP was to test already known mitigation methods against phosphorus losses in the field. LÄS MER

  3. 22. Metal Fractionation in Snowmelt Runoff : A Comparison between Ultrafiltration and Diffusive Gradients in Thin Films (DGT) techniques

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Sarah Lindfors; [2017]
    Nyckelord :Urban Runoff; Metals; Ultrafiltration; Diffusive Gradients in Thin Films;

    Sammanfattning : Urban runoff is a non-point pollution source deteriorating water quality of natural watersystems. The composition of urban runoff vary depending on land use, seasonal changes anddifferent surfaces that come into contact with the water. LÄS MER

  4. 23. Biolayer development in a slow sand filter in Ghana : Designing a filter that is benefiting the biolayer development under local conditions

    Uppsats för yrkesexamina på grundnivå, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Linda Hummerhielm; [2017]
    Nyckelord :slow sand filter; biolayer; development; långsamfilter; biofilm; utveckling;

    Sammanfattning : In 2015, the United nations presented the 17 Global Goals that would put an end to extreme poverty, inequality and climate change by 2030. One of these goals was clean water and sanitation. In 2015 1.8 billion people did not have access to clean water. LÄS MER

  5. 24. Förbehandling av skogsindustriellt avloppsvatten i pilotskala : Fluidiserad biofilmsprocess, robust försteg till luftad damm

    M1-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Författare :Liv Bergqvist; [2016]
    Nyckelord :biorening; försteg; pilotskala; MBBR;

    Sammanfattning : Skogsindustriellt avloppsvatten behöver genomgå flertalet reningsprocesser innan det kan återföras till recipient. Vid Stora Ensos bruk i Skoghall används en luftad damm med slamåterföring som biologisk rening. LÄS MER

  7. 25. Potential for using high frequency turbidity as a proxy for total phosphorus in Sävjaån

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Emma Lannergård; [2016]
    Nyckelord :surface water quality; high frequency monitoring; continuous monitoring; turbidity; in situ sensor; surrogate measurements; total suspended solids; total phosphorus; phosphorus; phosphorus load; load estimation;

    Sammanfattning : Transport of particles carrying nutrients and contaminants from land to sea is a challenge to monitor due to the high temporal variability in concentrations. Phosphorus is a particle associated nutrient, largely affecting the state of waters due to its effects on eutrophication. LÄS MER
