Surface water bodies are vital for providing ecosystem services, serving as habitats for diverse organisms, and supporting various human needs. However, these water sources are increasingly degraded by pollutants, which adversely affect biodiversity, aquatic ecosystems, and human well-being. Therefore, it is crucial to remediate these polluted surface waters to restore ecosystems, conserve biodiversity, and enable water reuse for various purposes. Nature-based solutions (NbS), such as the Floating Treatment Wetlands System (FTWS), offer an effective and innovative approach to address these challenges. FTWS is a cost-effective phytoremediation method that enhances quality by using local plants and floating rafts to remediate polluted water bodies.
