The objective of the current project is to develop a novel membrane-based technology for rapid detoxification of water borne contaminants. A multifunctional membrane is envisaged. We will first create a highly porous nano-fibrous backbone to achieve high internal surface area and low flow resistance (e.g., porosity > 80% can be achieved by electro-spinning technique). A tailored fiber size gradient will be developed to optimize membrane permeability and to achieve a complete removal of particulates and microorganisms. The nano-fibrous backbone will be further functionalized for selective removal of heavy metals and toxic organic chemicals as well as inactivation of microorganisms. High removal efficiency is expected due to the high internal surface area and the contaminant affinity of the membrane. Mobile prototype units will be developed for field trials. The proposed novel membrane product will allow adequate protection of human health from water borne contaminants. The product can be used for both centralized treatment and household applications. Other potential applications include rapid water treatment for disaster relief and light-weight water purification packs for outdoor camping activities.
