We have developed a silver (Ag) and copper (Cu) nanoparticle
impregnated activated carbon granular system, which can rapidly kill E. coli and other
microorganisms present in water. Therefore, we have scaled up this water
decontamination process from shake-flask experiments to continuous,
column-scale filters, in order to achieve a high throughput of clean, drinking
water from our column-filters. The aim of the present project is to further
improve the performance, by optimizing the column to work under gravity-flow
mode, so that it can be operated without any power source and at any point-of-use.
This will require experiments to improve the water-nanoparticle-bacteria
contact mechanism, in order to achieve better nanoparticle mediated cell-killing, simultaneously modeling the packed-bed flow and reaction profile, the way it takes place in the
filter-column. This will expose the student to a combination of chemical,
biochemical and materials engineering concepts, which is at the crossroads of
both basic science and engineering design expertise. The final product will be
a self-supported water-filter to produce safe, drinking water at a high
flow-rate, taking advantage of the very high reactivity of nanoparticles developed by
us.
