Constructed and Floating Wetlands for Sustainable Water Reclamation

Constructed Wetlands for Water Treatment: New Developments

Constructed wetlands (CWs) are currently regarded as established eco-technologies to treat water pollution. Although considered near-natural systems, they are totally engineered solutions for which research has been actively developed over the past decades. This paper provides a brief meta-analysis on the latest scientific publications in the field and an overview of the special issue focused o...

Monitoring and modelling of free water surface constructed wetlands

Integrated water management has encouraged the construction of small scale wastewater treatment plants to treat residual discharges. For this study, six free-water-surface constructed wetlands have been monitored from September 1998 till April 1999 to determine their operational efficiency. These natural systems have been constructed by the Flemish Land Authority (VLM) in Wontergem. Design load...

Constructed Wetlands and Other Approaches to Protecting Water Quality

The toxicity and estrogenicity of a final treated municipal effluent was examined while flowing through a constructed wetland in north-central Texas, USA. Fish data were collected, and a baseline wetland characterization was performed to assess wetland treatment potential for these effluent properties. Vitellogenin (VTG), gonadosomatic index (GSI), hepatosomatic index (HSI), and secondary sexua...

Constructed Wetlands : Treatment of Concentrated Storm Water Runoff ( Part A )

The aim of this research was to assess the treatment efficiencies for gully pot liquor of experimental vertical-flow constructed wetland filters containing Phragmites australis (Cav.) Trin. ex Steud. (common reed) and filter media of different adsorption capacities. Six out of 12 filters received inflow water spiked with metals. For 2 years, hydrated nickel and copper nitrate were added to siev...
