Floating treatment wetlands for synthetic greywaterremediation
… eutrophication and pollution, has led to treatment and/or recycling of the major fraction of domestic wastewater, which is grey wastewater, for non‒potable options. The major aim of this study was to evaluate the performance of FTWs for remediation of various pollutants from synthetic …

An Assessment of Floating Treatment Wetlands for Reducing Nutrient Loads from Agricultural Runoff in Coastal Virginia
Floating treatment wetlands (FTWs) are an innovative best management practice that can enhance the performance of traditional retention ponds by increasing removal of the nutrients nitrogen (N) and phosphorous (P). FTWs consist of floating rafts on which wetland plants are planted, allowing the …

Constructed treatment wetlands: Tools to attenuate diffuse agricultural pollution and enhance the biodiversity of eutrophic peat lake ecosystems
… excessive sedimentation of many rivers, lakes, wetlands, and estuaries. In excess, these contaminants cause diverse negative impacts on lake ecosystems such as prolific growth of phytoplankton and aquatic plants, toxic algal blooms and collapse of macrophyte beds, high turbidity and in-filling, …

Effects of Introduced Muskrat Populations on Emergent Vegetation in South Dakota Wetland
… wetland vegetation. Reduction of prairie wetlands has the potential to influence muskrat dispersal patterns and consequently, to reduce the beneficial influences of muskrats on wetland habitats. The objective of this study was to evaluate the changes in seasonal wetlands emergent …

Cold-climate constructed wetland applications in Canada and Northern China and modeling applications in the Canadian Arctic using SubWet 2.0
… removal efficiency in cold-climate constructed wetlands (CWs) and investigates the benefits, standing and practicability of using these systems to treat wastewater in Canada and Northern China. Treatment efficiencies defined by the Canadian and Northern China experience vary considerably. …

Threshold for complete submergence of Typha domingensis.
… its presence is desirable (as used in wastewater treatment wetlands) or unwelcome because of its aggressive growth habit.

Floating Treatment Wetland Nutrient Uptake Efficiency on the Salmon River
… ecosystems worldwide. Constructed floating treatment wetlands (FTWs) provide a potential nature-based solution for removing nutrients and other contaminants, yet their effectiveness in the natural environment is uncertain. This study evaluated FTW efficacy on the Salmon River, BC, where …

The physical role of transverse deep zones in improving constructed treatment wetland performance
… wetland and decreases performance in constructed treatment wetlands. In this thesis, field observations, experiments in a laboratory physical model, and mathematical modeling are used to explore the ability of transverse deep zones to mitigate the negative effect of short-circuiting on constructed …
