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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Nicolai Laufer; [2023-06-21]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Stockholms universitet/Institutionen för naturgeografi

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Seyed Reza Manafi Khosroshahi; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 4. 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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

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

    Abstract : 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.

    Abstract : The climate on earth keeps getting warmer where heat waves, eutrophication, rising sea levels, extreme weather like flooding, droughts and wildfires are an expanding problem. The focus of this bachelor thesis is to determine the potential of mitigating eutrophication and while contributing to blue growth by harvesting and make use of reeds like Phragmites australis and Arundo donax.
