Roll Pure – Rolling Water Purifier

Students of Indian Institute of Technology, Madras ,Ramesh Kumar, Swathy Ravindran won the award for developing a prototype of Roll Pure – Rolling Water Purifier. They carried their project work under guidance of Prof. Thalappil Pradeep.

In rural India, people, mostly women and kids, still carry water on their head or shoulder from available local water bodies, sometimes even carrying non-potable water. According to a survey carried out in 2012 by National Sample Survey Office (NSSO), about 54% of women from rural areas travel between 200 meters to 5 kilometers, average 20 minutes a day and additional 15 minutes to fetch water, amounting to 27 days of wages per annum for an individual. According to NSSO statistics, less than 10% of rural Indian household has the facility to treat water at home before its end use. This whole process results in physical fatigue of women and waterborne diseases such as diarrhea, anemia and child mortality hence many resulting postaffects. Roll Pure – Rolling water purifier provides solution for the overhead transportation of nonpotable. A user (women) can fill 40 liters of raw water from any water source (i.e. river, canal, pond, municipal hand-pump or tap etc.) and roll it to home, with minimum time required for transportation without any physical fatigue. To make fed water potable, a 1) hand-operable pump and 2) modular geo-genic contaminant specific cartridge is used. Modular geo-genic contaminant specific cartridge has 1) biocidal material, 1000 times biocidal then silver nanoparticles to kill bacterial and viral contaminants and 2) nano-composite material to remove soluble chemical contaminants. To get chemical and biological contaminant-free water with high output flow rate, a pressure differential is generated using bellow pump. Roll Pure can provide chemical and biological contaminant free water to India’s rural BoP with minimal transportation effort and without any power.

The Hon’ble President of India, Shri Ram Nath Kovind awarded the Gandhian Young Technological Innovation (BIRAC – GYTI) Award to Ramesh Kumar, Swathy Ravindran, Indian Institute of Technology, Madras at the GYTI 2018 Awards function held at Rashtrapati Bhawan on March 19, 2018.
