Executive Summary :

Per and polyfluoroalkyl substances (PFAs) have been used globally since the 1940s, with concerns over their presence in drinking water and soil. In India, PFAs are still unregulated, and their discarded precursors are an indirect source of contamination. PFAs have been detected in potable water and can cause severe health issues, including cancer, liver problems, immune system impairment, and developmental imbalances. Currently, incineration is the only method for complete mineralization of PFAs, but photodegradation is a potential alternative. Membrane-based processes for treating PFAs rely on conventional methods incapable of destroying PFAs. Future technologies should focus on separation and destruction of PFAs. The development of photocatalytically active, electrospun nanofibrous biodegradable polymer membranes can help address these issues. The project will involve developing photocatalytic nanoparticles embedded in biodegradable electrospun polymer membranes, characterization, performance analysis, and membrane cleaning and regeneration. The project aims to develop cost-effective, visible-light active biodegradable membranes for efficient separation and destruction of PFAs in continuous flow reactors.
