water quality in free-surface constructed wetland

“

The free surface constructed wetlands are known as a low energy green-technique to highly decrease a wide range of pollutants in wastewater and storm water before discharge into natural water. In this study, two spatial analyses, principal factor analysis (PFA) and hierarchical cluster analysis (HACA), were employed to interpret the effect of wetland on the water quality variables (WQVs) and to classify the wetland into groups with similar characteristics.
