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...
متن کاملPhosphorus retention in a newly constructed wetland receiving agricultural tile drainage water.
One measure used in Sweden to mitigate eutrophication of waters is the construction of small wetlands (free water surface wetland for phosphorus retention [P wetlands]) to trap particulate phosphorus (PP) transported in ditches and streams. This study evaluated P retention dynamics in a newly constructed P wetland serving a 26-ha agricultural catchment with clay soil. Flow-proportional composit...
متن کاملHeavy metals in a constructed wetland treating industrial wastewater: distribution in the sediment and rhizome tissue.
This study assessed copper and zinc distribution in the surface layer of sediment and rhizome tissue within the saturated surface vertical flow constructed wetland of CSBP Ltd, a fertiliser and chemical manufacturer located in Western Australia. Sediment and Schoenoplectus validus rhizome samples were collected at various distances from the inlet pipe while water samples are routinely collected...
متن کاملEffect of aging on phosphorus speciation in surface deposit of a vertical flow constructed wetland.
This study was conducted to determine phosphorus (P) species captured in a vertical-flow constructed wetland (VFCW) system combining a trickling filter followed by FeCl3 injection for phosphate coagulation. Suspended solids (SS) thus formed accumulated over time at the VFCW surface and transformed into a sludge deposit layer, which was shown to concentrate most of the P captured in the system. ...
متن کاملPhosphorus Accumulation Pattern in a Subsurface Constructed Wetland Treating Residential Wastewater
A horizontal subsurface flow constructed wetland was investigated after eight years of residential wastewater discharge (150 person equivalents). Twenty core samples distributed over the entire wetland were taken from the soil matrix. The distribution pattern of phosphorus (P) accumulation in the substrate of the wetland was determined using kriging technique and P sorption was related to the c...
