In this scenario, the Floating Treatment Wetland system (FTWs) are effective, eco-friendly, natural, energy-saving, and economical way of wastewater treatment. FTWs is a constructed floating raft has macrophytesgrowing above water surface with their roots are hangingbelow without touching the sediment. The plant roots uptake the nutrients from the wastewater and use it for their growth and reproduction. Also, provides habitat for microbial colonies. The microbes also enhance the treatment process by the breakdown of organic pollutants to simple inorganic nutrients that will be further absorbed by the plants. Furthermore, plant roots entrap solid particles and maintain a hydraulic flow between roots and water below FTWs. In this review article, the structure and design of FTWs, the features and operational parameters of FTWs, the role of plants, mechanism of pollutant removal, the efficiency of FTWs in the removal of nutrients, organic+matter and heavy metals, FTWs status in India and finally the points to consider in installation and maintenance of FTWs are discussed.
