IIT rolls out water purifier

According to a survey by “National Sample Survey Office (NSSO)”, about 54% of the Indian women from rural areas travel between 200 meters to five kilometres daily to get drinking water. 

Thus, a water carrier with inbuilt water purification system is essential in rural India to solve this problem. In the project “Roll Pure”, IIT Madras researchers have used 1,000 times efficient biocidal nano materials to perform in-situ disinfection, and nano composite materials to remove soluble geo-specific contaminants.

The project lead Ramesh Kumar Soni said that in order to use the unit, water volume up to 40 litres is filled inside the polybag from open water bodies and unit is rolled to the point of end use. During rolling, biocidal material kills available biological contaminants and dead debris of same is filtered. Pressure differential required for filtration of dead debris and chemical contaminants is developed by a bellow pump.
