Abstract

Hollow porous polymeric fibers have been fabricated to facilitate the adsorption of analyses on chemically modified synthetic membrane for rapid decontamination of contaminates. The pocket water filtration cartridge which could fit into plastic water bottle of standard nozzle size has been developed using polymeric membrane and electro spun nanofibers-based changeable pre-filters. During and several days after flooding, there is serious shortage of water to drink, cook, washing or cleaning as water become contaminated. The unique feature of our air droppable water filtration cartridges enables mass scale supply of drinkable water during natural calamities. This complete indigenous polymer nanofibers-based product has already successfully completed field trials at two major Indian government organizations for sustained supply of drinkable water. The hydration packs for long-range reconnaissance patrol have also been designed and developed with this portable filtration cartridges to supply the potable water during uninterrupted surveillances. Our clean and safe water solution has many added advantages compared to commercially available products in terms of higher filtration rate, easier operation and custom specific design to address the polluted water treatment challenges at much reduced cost.
