Floating Treatment Wetlands (FTWs) are a versatile NbS that excels in phytofiltration, providing effective water depollution, wastewater treatment, and ecosystem regeneration.
These systems feature buoyant platforms that support aquatic plants like reeds and vetiver grass, whose roots extend into the water to perform phytoremediation by absorbing excess nutrients, heavy metals, and organic pollutants.
In addition to their phytofiltration capabilities, FTWs enhance water quality by promoting biofilm activity, which breaks down contaminants, and by physically filtering suspended solids, improving water clarity.
Their application is particularly effective in post-mining landscapes, where they treat metal-laden wastewater and stabilize degraded aquatic ecosystems. FTWs also address agricultural runoff, mitigate eutrophication in urban waterways, and support regenerative aquaculture practices.
Beyond water treatment, FTWs contribute to the regeneration of soil and water systems, foster biodiversity, and provide sustainable uses for waste biomass in bioenergy or compost, promoting a circular economy.
Their low cost, adaptability to various environments, and potential for community participation make FTWs an attractive solution for restoring ecological balance, enhancing aesthetic value, and supporting livelihoods.
This holistic approach underscores their value as a Nature-based Solution for addressing Southeast Asia’s environmental and socio-economic challenges.
