Bacterial Source Tracking of E. coli in a Constructed Wetland
… to identify sources of fecal contamination in a constructed wetland. Nucleotide sequence differences in the <em>Escherichia coli </em>malate dehydrogenase (<em>mdh</em>) gene were used to distinguish between strains isolated from pigeon and cattle feces. Fourteen <em>E. coli</em> isolates were …

A mathematical model of the nitrogen cycle in a constructed wetland
A model was developed using contemporary wetland theory to predict the fate of nitrogen runoff in a constructed wetland. The model utilizes nitrogen concentrations of influent water as system inputs. The model is three-dimensional, one dimensional in time, and two dimensional in space. The physical …

Mechanisms of lead and zinc removal from lead mine drainage in constructed wetland
"Constructed wetlands treating different mine drainage were designed based on one-for-all criteria instead of being customized and engineered carefully based on the characteristics of the mine drainage and wetland substrates due to lack of detailed knowledge about metal removal mechanisms. This …

Simulation and Optimization of a Constructed Wetland for Biomass Production and Nitrate Removal
… of perennial grasses for bio-ethanol production. Constructed wetlands offer a promising nutrient removal mechanism while also providing an ideal environment for the growth of such grasses. In the present work, a hypothetical wetland system is designed to treat non-point source nutrient loadings …

Analysis of the efficacy of a constructed wetland in treating human fecal contamination
The efficiency of a system of constructed wetlands in treating non-point source pollution, particularly, human fecal contamination, was evaluated by collecting and analyzing water samples using both conventional culture-based methods to enumerate indicator bacteria and quantitative polymerase chain …

An Investigation of the Performance of a Constructed Wetland in Treating Urban Stormwater
… the pollutant removal performance of a constructed wetland treating stormwater runoff from a residential townhome complex in Manassas, Virginia. The facility was constructed by retrofitting a dry detention basin to retain a permanent shallow pool and included additional temporary storage …

Using Free Water Surface Constructed Wetland for the Mitigation of High PH Secondary Effluent From Municipal Wastewater Treatment Plant
… the summer and is assessing the potential of a constructed wetland (CW) system to mitigate these operational issues. In order to design a CW, a bench-scale experiment was conducted to identify the best available substrates and operational conditions in the laboratory. A short-term assessment of …

Cold-climate constructed wetland applications in Canada and Northern China and modeling applications in the Canadian Arctic using SubWet 2.0
… of pollutant 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 …
