  1. 1. Modeling BOD removal in free watersurface constructed wetlands with variable residence time-based methods

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Degefu Yohannes Sebro; [2021]
    Keywords : BOD removal; Free water-surface constructed wetlands; VART-BOD; models; dynamic diffusion zone; Technology and Engineering;

    Abstract : Constructed wetlands (CWs) have been applied for several years in the removal process pollutants from secondary treatment plants and stormwater. In this paper, the Variable Residence Time (VART) model for solute transport in streams was extended to simulate the BOD removal process in free water surface flow constructed wetlands (FWS CWs).

  3. 2. 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

  4. 3. The Effects of Erosion-control Structures and Gully Erosion on Groundwater Dynamics Along the Kromrivier, Eastern Cape, South Africa

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Vincent de Haan; [2016]
    Keywords : Gully erosion; wetland; groundwater dynamics; erosion-control structures;

    Abstract : The Palmiet wetlands located along the Kromrivier in the Eastern Cape province of South Africa have experienced severe degradation through gully erosion during the past decennia which has been threatening the water quality and water security of large towns in the Nelson Mandela Metropolitan hub. Water scarcity is a growing problem in this region as a result of land degradation and growing erratic rainfall patterns. READ MORE

  5. 4. Metal and metalloid sequestration in a constructed wetland system for treatment of landfill leachate during 2003-2012

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Tatsiana Bandaruk; [2013]
    Keywords : ;

    Abstract : Landfill leachate treatment can be expensive and energy consuming when carried out in wastewater treatment plants. However, there can be several possible solutions for reducing cost and energy requirements and one of them is on-site biological treatment of polluted landfill leachate in constructed wetland systems.

  6. 5. Wastewater Treatment and Reuse through Constructed Wetlands Restoration of EU-Facultative Lagoons in Vientiane, Lao PDR

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Hui Su; [2012]
    Keywords : Earth and Environmental Sciences;

    Abstract : The massive infrastructure investments of the last 10 years in Vientiane (capital of Lao PDR) saw the city’s drainage network and wetlands being replaced by hydraulically more efficient cement-lined channels designed to ensure flood protection. As a result, water quality entering the receiving That Luang wetland has significantly degraded. READ MORE
