Water purification is a big deal in developing countries. For people in rural locations, getting clean water is sometimes a problem. Dr. Theresa Dankovich from Carnegie Mellon and WATERisLIFE want to change that.
The two partners have developed the Drinkable Book, the first-ever manual that gives safe water tips and serves as a tool to kill deadly waterborne diseases by providing the reader with an opportunity to create clean, drinkable water from each page.
Dankovich began work on the technology when she was earning her doctorate at McGill University, continuing it at the University of Virginia’s Center for Global Health. She has now formed a non-profit company, pAge Drinking Paper, to get the book into production and distribution.
Each book is printed on technologically advanced filter paper, capable of killing deadly waterborne diseases. Each page is coated with silver nanoparticles, whose ions actively kill diseases like cholera, typhoid and E. coli.
Once water is passed through the filter, bacteria count is reduced by over 99.99%, making the filtered water comparable to tap water in the United States of America.
The book can provide a user with clean water for up to four years. Every page of the book is made up of two filters, each one of which in turn being capable of cleaning up to 26 US gallons (100 liters) of water – one book should reportedly be able to handle one person’s water needs for four years.
The pAge filters have been tested with over 25 different water sources in 5 countries, and the partners are starting to scale up their operations to pilot the filters in a few villages in Africa and Asia. The most recent field trial was conducted in June 2015 with iDE-Bangladesh in southern Bangladesh, which focused on culturally appropriate design and product marketing.
The Drinkable Book was voted one of the best inventions of 2015 by Time
