Groundwater Quality Impacts from a Full-Scale Integrated Constructed Wetland

Groundwater Quality Impacts from a Full-Scale Integrated Constructed Wetland

Effects of a constructed wetland and pond system upon shallow groundwater quality.

Constructed wetland (CW) and constructed pond (CP) are commonly utilized for removal of excess nutrients and certain pollutants from stormwater. This study characterized shallow groundwater quality for pre- and post-CW and CP system conditions using data from monitoring wells. Results showed that the average concentrations of groundwater phosphorus (P) decreased from pre-CW to post-CW but incre...

Efficiency and kinetic modeling of removal of nutrients and organic matter from a full-scale constructed wetland in Qasr-e-Shirin, Iran

Background: This study assessed the removal of organic material and nutrients from full-scale subsurface flow (SSF) constructed wetlands (CWs) followed by anaerobic stabilization ponds under environmental conditions. Methods: The effluents were distributed evenly in 12 reed beds. Samples were taken twice monthly for a total of 6 months from several points in the wetland. Biochemical oxygen dema...

Seasonal Variation of Nutrient Removal in a Full-Scale Artificial Aerated Hybrid Constructed Wetland

To improve nutrient removal, a full-scale hybrid constructed wetland (CW) consisting of pre-treatment units, vertical-baffled flow wetlands (VBFWs), and horizontal subsurface flow wetlands (HSFWs) was installed in August 2014 to treat sewage wastewater. Artificial aeration (AA) was applied continuously in the VBFW stage to improve the aerobic condition in the hybrid CW. Water samples were colle...

Constructed Wetland Treatment Plant Constructed Wetland Microbial Fuel Cells

18 This work aimed at determining the amount of energy that can be harvested by 19 implementing microbial fuel cells (MFC) in horizontal subsurface constructed wetlands 20 (HSSF CWs) during the treatment of real domestic wastewater. To this aim, MFC were 21 implemented in a pilot plant based on two HSSF CW, one fed with primary settled 22 wastewater (Settler line) and the other fed with the eff...
