Bioremediation of chlorinated ethanes and ethenes in vertical flow engineered wetland systems
… contaminated groundwater using vertical flow engineered wetland systems were investigated in microcosm and column studies. Experiments on environmental and biogeochemical factors that affect system performance were conducted, and a numerical model involving advection, sorption, and sequential …

Towards a mechanistic understanding of contaminant attenuation and greenhouse gas emissions in open-water engineered wetlands
Engineered wetlands offer a sustainable supplement to conventional water and wastewater treatment by harnessing biological processes which occur naturally in the environment. In macrophyte-free open-water engineered wetlands, design parameters of a shallow water column and geotextile liner select …

Geotechnical investigation of Montrose wetland site
… site and to aid in the creation of a proposed engineered wetland at Montrose, West Virginia. The tests performed in the laboratory to obtain the soil properties were: water content, Atterberg limits (liquid and plastic limits), grain size (sieve analysis and hydrometer), specific gravity, field …

Effectiveness of Wastewater Treatment for Selected Contaminants Using Constructed Wetlands in Mediterranean Climates
<p>Constructed wetlands for wastewater treatment (CWWT) are engineered wetland systems created to emulate the processes that occur in natural wetlands. This research focused on looking at the effectiveness of selected contaminant removal based on pilot-scale and full-scale case studies conducted in …

Degradation of Chlorinated Hydrocarbons in Groundwater Passing Through the Treatment Wetland at Wright-Patterson Air Force Base: Analysis of Results Collected During 2001-'06
Constructed wetlands are an efficient and cost effective means for chlorinated aliphatic hydrocarbon remediation, and will therefore continue to gain momentum as an accepted treatment by the US EPA (U.S. EPA, 1995; Amarante, 2000; Lien, 2001; WETPOL, 2009). The treatment options for chlorinated …
