Abstract

Constructed wetland (CW) is regarded as an effective and eco-friendly technique for water purification with macrophytes. This study built lab-scale CW models with three macrophyte monocultures to test for species-specific contaminant removal properties and to evaluate the targeting macrophyte in majority-scaled density plantings comprising of a 50%, 70%, and 90% comparative planting density. First-stage results demonstrated that Giant Bulrush outperformed the two other species in terms of the overall water quality yielded. All monoculture cells performed well in enhancing DO levels and turbidity reduction. COD and conductivity remained high but consistent through Stage 1 run, indicating leaching from the soil and underlaid gravels. Giant Bulrush was therefore used as the target macrophyte to mix with the other two species in equal density at the prescribed ratios for Stage 2 experiments. We monitored both water quality parameters and the presence of Escherichia coli in the water and soil in the system.
