Nanocomposite Devices for Water Treatment and Land Remediation
Nanotechnology offers huge potential in water treatment, given the extremely high reactivity and capacity of nanoparticles, and the novel reactions that can be generated at the nano-scale. This presentation outlines recent research carried out at the University of Brighton and with European academic and industrial partners aimed at developing flexible, low-cost and non-toxic nanocomposite devices for water treatment and land remediation. Prototype devices based on reactive nanoparticles incorporated into stable polymer, silica and carbon-based “scaffolds show considerable utility in the rapid removal of a range of problem contaminants from water and effluent streams. The use of a flexible (and low-cost) “scaffold as a host for the nanoparticles allows the devices to be produced in a range of geometries, which permits their use in a variety of configurations at point of treatment or as decentralised solutions, e.g. as a high-throughflow filter for liquids, or as a bed reactor or pipe liner device, whereby contaminated water flows over the surface of a series of 2D (i.e. flat) devices which rapidly strip contaminants from the overlying water. The potential advantages of the nanocomposite approach are discussed and evaluated, and the potential for wider application of these and similar devices in water treatment and land remediation critically evaluated.
