  1. 1. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  3. 2. 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.

  4. 3. Utfodringsstrategier för minskade metanutsläpp från enterisk fermentering hos mjölkkor

    University essay from SLU/Dept. of Agricultural Research for Northern Sweden

    Author : Lisa Stensson; [2021]
    Keywords : idisslare; växthusgas; foder; hållbarhet;

    Abstract : Metan är en potent växthusgas som delvis produceras under fermentering i våmmen på idisslare. Utsläppen av metan från enterisk fermentering står idag för en betydande andel av utsläppen från hela jordbrukssektorn. READ MORE

  5. 4. Causes and impact of surface water pollution in Addis Ababa, Ethiopia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Malin Eriksson; Jonathan Sigvant; [2019]
    Keywords : Akaki river; E. coli; health risk; interview study; irrigation; physico-chemical parameters; water samples; Akaki; E. coli; fysikalisk-kemiska parametrar; hälsorisker; intervjustudie; vattenprover;

    Abstract : Surface water is globally becoming more and more a scarce resource, and in Addis Ababa the capital of Ethiopia, river water quality has been degraded due to anthropological forcing for many years. Therefore, the study objective was to investigate causes and impact of surface water pollution in Kebena and Great Akaki rivers. READ MORE

  6. 5. Stream Restorationand Mitigation of Nitrogen in the Hyporheic zone : Interpretation of tracer tests from Tullstorps brook

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sunna Mjöll Sverrisdóttir; [2019]
    Keywords : Hyporheic Zone; Stream Restorations; Nitrate Mitigation; Tracer test; Solute Transport; Eutrophication; Nitrogen;

    Abstract : Streams and rivers have been modified in the past centuries for agricultural purposes. The Baltic Sea suffers from problems regarding eutrophication. Regulations of point-sources have decreased nutrient levels, but for a scattered source of nutrient pollution, streams are important. READ MORE
