The objective of this study is to assess the performance of the vertical flow-constructed wetland (VFCWL) in the removal of direct fast orange dye from synthetically prepared wastewater with four wetland systems, namely, without plants (CWC), with vetiver (CWV), Canna indica (CWCI) and Hibiscus rosa-sinensis (CWH), and to compute the irrigation water quality indices like sodium absorption ratio (SAR), percentage sodium (% Na), magnesium absorption ratio (MAR), Kelly’s ratio (KR), residual sodium bicarbonate (RSBC) and permeability index (PI). The filter medium consists of coarse gravel, medium gravel and garden soil. The treatment potential of the wetlands was evaluated using the parameters pH, electrical conductivity, colour and chemical oxygen demand (COD). The results proved that the wetlands CWC, CWV, CWCI and CWH resulted in 67%, 83%, 75% and 33% in colour removal and 54%, 87%, 67% and 34% in the removal of COD, respectively. This study proves that the VFCWL with vetiver plants is an effective mechanism in the removal of direct fast orange dye.

摘要

The objective of this study is to assess the performance of the vertical flow-constructed wetland (VFCWL) in the removal of direct fast orange dye from synthetically prepared wastewater with four wetland systems, namely, without plants (CWC), with vetiver (CWV), Canna indica (CWCI) and Hibiscus rosa-sinensis (CWH), and to compute the irrigation water quality indices like sodium absorption ratio (SAR), percentage sodium (% Na), magnesium absorption ratio (MAR), Kelly’s ratio (KR), residual sodium bicarbonate (RSBC) and permeability index (PI). The filter medium consists of coarse gravel, medium gravel and garden soil. The treatment potential of the wetlands was evaluated using the parameters pH, electrical conductivity, colour and chemical oxygen demand (COD). The results proved that the wetlands CWC, CWV, CWCI and CWH resulted in 67%, 83%, 75% and 33% in colour removal and 54%, 87%, 67% and 34% in the removal of COD, respectively. This study proves that the VFCWL with vetiver plants is an effective mechanism in the removal of direct fast orange dye.
