  1. 16. 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.

  3. 17. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Gabriella Corbee; [2021]
    Keywords : Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Abstract : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. READ MORE

  4. 18. Population dynamics of the horned grebe in constructed wetlands in Östergötland.

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Johanna Pellnor; [2021]
    Keywords : Biodiversity; Canadian pondweed; Common roach; Horned grebe; Pike; Population dynamics; Wetland;

    Abstract : The population size of the horned grebe, Podiceps auritus, is declining in most of the world due to loss of wetlands, deteriorating water quality and establishment of predatory fish such as pike, Esox lucius, in former fish free wetlands. The horned grebe is now globally classified as vulnerable. READ MORE

  5. 19. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Hani Yahya Ali Shubail; [2020]
    Keywords : Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

    Abstract : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. READ MORE

  6. 20. Flow pattern analysis of a Surface Flow Constructed Wetland : Treating surface runoff and landfill leachate water from the Löt waste management site

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Max-Bernhard Alm; [2020]
    Keywords : Surface flow constructed wetland; flow pattern analysis; numerical model;

    Abstract : The waste management and recycling company, Söderhalls Renhållningsverk (SÖRAB) have constructed a surface flow wetland in order to treat surface runoff from the waste management site, Löt. The contaminated water passes several treatment steps until it reaches the wetland and a subsequent soil infiltration step. READ MORE
