In 2014, American scientists and designers who participated in the initiative “Water is life”, created a book that purifies water.
The “drinkable book” or potable book contains 20 pages that actually have special filters. Pages contain silver and copper nano-particles that kill bacteria in the water passing through the book.
This feature has been crowned with success at the 250 th national conference of the American Chemical Society in Boston, USA, announced August 19 BBC.
The conference took place from 16 to 20 August. During this, the first tests were made and the book appeared extremely effective. The nano-particles are able to remove 99.9% of harmful bacteria in the water. Each page of the book can be detached and be glued to a plastic container, which represents the packaging of the book.
The tests also show that every page can purify up to 100 liters of water and a book is sufficient for a human being for 4 years. Furthermore, the book educates people on hygiene and offers health advice.
The invention is intended for developing countries where the need for clean water is the most important. Research shows that an inhabitant of six on the planet lack access to safe drinking water and many people living in the Third World do not even imagine the risks associated with unfiltered water.
