Heavy Metals Removal from Domestic Sewage in Batch Mesocosm Constructed Wetlands using Tropical Wetland Plants

Constructed wetlands are an affordable and reliable green alternative to conventional mechanical systems for treating domestic sewage. This study investigates the potential of 14 tropical wetland plant species removing heavy metals from sewage through bioconcentration factor (BCF), translocation (TF), enrichment (EF), geoaccumulation index (Igeo) using batch mesocosm studies. Plants with BCF > 1 TF classified as phytoextractors, while < phytostabilisers. The results indicate that 11 out magnesium phytostabilisers, 10 calcium no demonstrate ferrum phytoextraction properties. As manganese phytoremediation, only three depicted phytostabilisation (EF) all studied ferum a reference metal in soil samples decreased after phytoremediation experiments, indicating depletion mineral (EF 2). All generally uncontaminated based on Igeo indices. Based factors indices, it is suggested plants may have facilitated removal uptake into tissues roots.
