Drinkable book

An innovative “drinkable book” with chemically altered pages which can filter out bacteria may have brought us nearer to a low-cost solution to a problem plaguing more than 750 million people worldwide: access to clean drinking water.

The new “book” designed at Carnegie Mellon University in the US has gone through a number of tests and proved that its pages, basically water filters containing bacteria-killing silver and copper nanoparticles, are able to turn dirty water – even that mixed with raw sewage – into 99.9 percent pure drinking water.

The drinkable book is a tool that teaches people safe water drinking habits and provides them with technologically advanced filter paper that kills waterborne diseases. The filtered water meets EPA (US Environmental Protection Agency) standards and is comparable to North American tap water. One page can filter as many as 100 liters of water.

The newest results of trials carried out in South Africa, Ghana and Bangladesh were announced at the 250th national meeting of the American Chemical Society in Boston, US.
