Effects of open water on the performance of a constructed wetland for nonpoint source pollution control

Water Science and Technology, 2010
The seasonal performance of four differently configured constructed wetland systems was compared for the treatment efficiency of nonpoint source pollution. Dead plants in the constructed wetlands increased the nitrogen removal rate during winter by providing organic carbon, which is essential for the denitrification process.
