This 'drinkable book' turns raw sewage into drinking water
We tend to take clean water for granted as a commodity, but lack of access to drinkable water is a major issue across the globe and it influences health, child development, quality of life and eradication of poverty. According to the World Health Organization/ UNICEF Joint Monitoring Project, the amount of people that do no have access to drinkable water is currently 663 million.
Water is Life, a group that's mission is to provide clean water, sanitation and hygiene programs to save lives and transform communities has been developing a type of paper that can be used as an incredibly powerful, easy-to-use and cost-effective filter. The paper was tested with raw sewage that contained millions of bacteria and the results showed that it managed to clean the liquid of 99.9% of the the original impurity.
The paper was used to print a book that teaches about good habits for cleaning water and at the same time each page contains silver and copper nano-particles that can be used as filters. One single page can purify 26 gallons of water and each ear can provide enough clean water for one individual for four years.
Here is a video that explains the process:
