This document describes an electrified nanofilter that can help address waterborne diseases in rural India. It works by coating cotton fabric with silver nanowires and carbon nanotubes, then electrifying it. When water passes through, bacteria are killed by the silver and electricity. Compared to other filters, it is more effective at removing bacteria, protozoa, and viruses while being low-cost, easy to use, and requiring little electricity. While it may not remove all chemicals, its advantages could significantly improve access to safe drinking water for rural communities in India.

3. Introduction




Water is the prime element responsible
for life on earth
Water covers 71% of earth surface
Still in every part of world around one
billon people lack access to safe water
Becoming victims to waterborne
diseases

4. Rural India
India -2nd most populous country
Out of 1.42 million villages
1,96,813 are effected by
contamination of water

One-third of India's 647 districts
has no water fit for drinking

72% of rural India has no
improved sanitation
Ranks 120th among 122 nations

5. Waterborne diseases






Traveling from north to south in
India there is a huge contrast in
water availability & scarcity
Underlying this imbalance in water
availability is the issue of waterborne diseases.
Top 3 deadly waterborne diseases
are: diarrhoea ,malaria ,cholera
It accounts 50% sickness in India
Leading to death of over one lakh
and making 70 million sufferers
What is the solution for this ?

6. PRINCIPLE OF ELECTRIFIED NANO
FILTER :




Silver has long been known to have
chemical properties that kill bacteria &has
property of highest electric conductivity
Nanofiltration- An uprising filtration
technique
The principle or key is coating the filter
fabric-ordinary cotton with nanotubes and
silver nanowires an then electrifying it.
This approach combines several materials
spanning three very different length scales
with simple dying based fabrication.

7. Process of filtration:



Dipping plain cotton cloth in a hightech broth full of silver nanowires and
carbon nanotubes, have developed
filter that could easily be implemented
to purify water.
A continuous structure along the
length, you can move the electrons
very efficiently and really make the
filter very conducting.
Process in general filters that
physically trap bacteria and allow the
clean water .but this filter instead of
physically trapping bacteria

10. ADVANTAGES:






It is low cost filter.
Process of filtration is 80,000 times
faster than existing filters.
Can be easily used in remote areas.
No clogging problem.
Low electricity requirement.
No bio fouling.

11. DISADVANTAGES:

Cannot wipe out some of the chemicals

Usage of the multiple filters.

12. Conclusion
By adapting to this electrified nano filtration
process we can improve the prevailing
situation faced by the rural people as it can
be used from macro (national & state) level to
the micro (district & village) level.
