Performance assessment of hybrid constructed wetlands planted with different macrophytes for industrial wastewater treatment

ABSTRACT

The aim of this study was to assess the performance of a laboratory-scale Hybrid Constructed Wetland (HCW) for industrial wastewater treatment planted with different macrophytes at different hydraulic retention times (HRT). The results revealed that the HCW planted with Phragmites australis and Lemna minor (PA/LMs), and the HCW planted with Typha latifolia and Lemna minor (TL/LMs) were able to improve the physicochemical proprieties of industrial wastewater, and were efficient enough to remove the heavy metals.
