Priced at Rs 300, the filter uses four-stage purification process which uses combination of ultra violet (UV) disinfection and plant extracts among others.
And making it a true invention, the filter doesn’t require high maintenance, and electricity.
The three students from IIT Kharagpur -- Deepesh Kumar, Pankaj Agarwal and Shobhit Jain, worked hard for one year to come up with this filter. The trio has already applied for three patents — first on its filtration system, secondly the use of plant extracts, and thirdly sand filtration process.
A bit elaboration on the Rs 300 Water Filtration System:
The salient fact about the filter is that it uses solar energy for ultra violet disinfection. In other filters usually, a separate source powered by electricity is employed for UV disinfection.
Another interesting aspect about the filter is that four kinds of plant extracts are used in it, which the IITian trio has named it “Huedor” (water in Greek).
Such is the buzz about the worthiness of the system, that earlier this year, the trio had been invited to RICE University in USA to display their product in the largest business competition of the world. The purification unit not only received great response their; but the project also received much needed VC money.
Regarding the future of this purification system, the IITians inform that, keeping in view the high levels of arsenic contamination in parts of Bengal; they are working on to incorporate system that would be able to bring down the arsenic level in water or make it completely free of the toxic element.
Availability:
The young inventors are planning to complete the pilot-testing stage in villages of West Bengal by April, 2012. If all goes well, the product will be available throughout India and the rural markets of Africa by the beginning of September 2012. --------
