  1. 1. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  3. 2. Water quality monitoring with Sentinel 2 in small watercourses : Investigating the measurability of phosphorus using proxy data

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Caroline Morin; [2023]
    Nyckelord :Optical remote sensing; Sentinel 2; Phosphorus; Total suspended matter; Turbidity;

    Sammanfattning : Inland water has for a long time showed vast stress due to eutrophication, mainly caused by increased levels of phosphorus. Applying remote sensing as a tool for monitoring water parameters has long been used. LÄS MER

  4. 3. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    Magister-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Seyed Reza Manafi Khosroshahi; [2022]
    Nyckelord :Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Sammanfattning : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. LÄS MER

  5. 4. Modellering av fosfordynamik i Stora och Lilla Ullfjärden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Walter Cassel; [2022]
    Nyckelord :HYPE; fosfordynamik; internbelastning; fosforbelastning; Stora Ullfjärden; Lilla Ullfjärden; algblomning;

    Sammanfattning : Algblomningar är ett problem i många svenska sjöar, speciellt när cyanobakterier blommar och producerar cyanotoxiner. En förutsättning för algblomningar är en tillräckligt hög fosforhalt, då fosfor ofta är det begränsande näringsämnet för cyanobakterier. LÄS MER

  7. 5. Initial nutrient retention capacity in a constructed wetland : Evaluating the effectiveness of a newly constructed wetland to reduce eutrophication symptoms in a Baltic Sea bay in northern Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Elin Eriksson; [2021]
    Nyckelord :retention; constructed wetland; total phosphorus; total nitrogen; nutrient dynamics; northern latitudes; nutrient mitigation measure;

    Sammanfattning : Since the turn of the last century, a substantial increase in nutrient load to the Baltic Sea is apparent. Adding the ongoing environmental change with raising temperatures and increased precipitation, this will continue to have a prominent environmental impact on our coastal ecosystems, especially in northern latitudes.
