The Drinkable Book holds promise of safe water

Advanced filter paper made of silver nitrate proven to check waterborne diseases such as cholera, e-coli and hepatitis.

    It is called The Drinkable Book. Its pages are made from technologically advanced filter paper made of nanoparticles of silver nitrate that eliminate the bacteria behind waterborne diseases such a cholera, e-coli and hepatitis.

    It was invented over several years by Teresa Dankovich, a chemist a Carnegie Mellon University in the US city of Pittsburgh.  

    "We were testing these filter papers in a few different countries and we just evaluated the water quality before and after filtration in South Africa, Ghana, and Bangladesh," Dankovich told Al Jazeera.

    The filters have also been tested in Haiti and Kenya. The results were that 99.9 percent of the bacteria were killed by the papers, which is basically as good as tap water.

    More than 500 million people lack access to clean water, and 842,000 people die each year from drinking unsafe water, according to a report last year by the World Health Organization.

    Al Jazeera's Gabriel Elizondo reports from New York.
