NanoSponge project

The objective of the NanoSponge project was to develop a practical method for removal of organic contaminants at concentrations as low as one ppb (parts per billion). In a manner similar to that for organic polymers, nanoporous polymers offer flexibility in processing and can be fabricated into granular solids, powders and membranes.

To provide long lasting multi-layer membrane, consisting of an organic naosponge layer mechanically supported by either a porous ceramic carrier or porous polymeric hollow fibre carrier, including a new regeneration method for the inorganic/organic filter. The organic membrane that cover completely the porous surface of the carrier. To take advantage of the potential absorption at solid-water interfaces, which effectively removes highly toxic organic contaminants from water by forming inclusion complexes. As a result, organic molecules will be encapsulated within the nanosponge material and therefore water will be purified. International there is concerns about the sustainability of the world's groundwater sources traditionally used for human consumption which are driving the exploration of alternative sources such as surface water and even oceans.
