Biogeochemistry of Constructed wetlands

Constructed Wetlands in the British Isles

Natural and engineered wetlands are increasingly being used around the world for the treatment of effluents. Many studies have demonstrated the significant reduction of BOD, COD, suspended solids and nutrients that takes place between the inflow and outflow water {, while other wetlands have also been successfully used for the removal of metals from acid mine drainage. More recently, work has been carried out to look at their use in removing complex organic pollutants from a variety of effluent streams, including road run-off. Constructed wetlands are currently being piloted as Landfill leachate and storm-water runoff treatment systems.

Constructed Wetlands under Study

We are currently looking at the biogeochemistry of three wetlands in Wales on one in South East England.
