Innovative Floating Treatment Wetland Systems

Floating Treatment Wetland Systems (FTWS) are innovative platforms made from local waste materials that effectively cleanse polluted water bodies. Designed by hydrologist Soni Pradhanang, these platforms consist of buoyant mats topped with plants that absorb pollutants through their roots, significantly reducing contaminants like nitrates, phosphates, and heavy metals. For example, results from recent projects in Nagda, India showed a 99% reduction in nitrate levels and a 56% reduction in iron, highlighting their efficacy in improving water quality. By utilizing inexpensive, locally sourced trash, these systems present a cost-effective solution for communities struggling with environmental pollution where traditional water treatment options may be unaffordable.
