A Book That Filters 4 Years of Drinkable Water

By Anupum Pant

I’ve written a lot about water in the past. No wonder drinking water is such a precious commodity. Still, not many have access to clean water. About a 7th of the whole world’s population don’t have clean water to drink. Every year about 3.4 Million people die out of water borne diseases.

A group of people who go by the name WaterisLife are putting in everything to change that. By working with a group of scientists from Carnegie Mellon and the University of Virginia, they have been able to come up with a novel idea that could change this. They call it the drinkable book. 

Drinkable book is a book full of cards that have been coated with silver nanoparticles. These cards bear the ability to filter dirty water and reduce the count of bacteria in it by about 99.9%. It can kill the bacteria that causes diseases like cholera, typhoid and E. coli., producing drinkable water that is as pure as tap water used in the US. Each page of this book can filter about 30 days of drinkable water. In fact, each page contains the instructions to filter water properly too. The whole book can provide 4 years of potable water. Definitely a boon to the developing countries.
