Paper Summary

A wetland system was used to clean polluted water from a reservoir. The system removed almost half of the pollutants like COD, TP, TN, and NH+4-N. The wetland works by using physical, chemical, and biological processes to clean the water. Pollutants were mostly removed at the front of the wetland, with the top part being the most effective.
