Phytoremediation of Stormwater by Floating Treatment Wetland

Floating treatment wetland (FTW) is a promising technology for nutrient and metal removal from stormwater. Plant the key component of an FTW, facilitating pollutant through plant uptake microbial actions. A careful selection species essential efficient FTW. This paper reviews available literature focusing on role plants in FTWs to identify research gaps provide future directions. From field-scale research, it was identified that Baumea articulata, Phragmites australis, Chrysopogon zizanoidses Carex appressa were high-performing nitrogen phosphorus removal. It found presence community largely depends upon species. Microbial abundance are also limited by environmental factors such as pH, dissolved oxygen concentration. Multi-species plantation widely adopted FTWs, but its effectiveness not proven even though has potential enhanced under right condition. Development harvesting strategies permanent pollutants FTW system depend season distribution tissue. review provides critical insights into selection, microbes, multi-species system.
