A water purification filter: the Drinkable Book

Each year, 3.4 million people die from diseases contracted through polluted water. The Water is Life organisation has partnered with scientists and engineers to put a stop to that.

Their cooperation has led to a revolutionary innovation: a book whose pages, used as filters, can destroy 99.99% of the bacteria in polluted water. The result is safe, clean drinking water.

What’s more, the orange pages of the book bear educational messages. They teach us about what we can do in our immediate environment in order to prevent water pollution.

The book is extremely cheap to produce, at present it is recognised as the cheapest water purification solution available. A single page of filter paper can produce clean drinking water enough for thirty days, while a single copy of the book can solve the problem for a person in a developing country for up to 4 years.

The pages of the book contain silver nanoparticles, which are well known for their excellent disinfection effect, which makes them one of the most widely used varieties of nanoparticles. As nanoparticles can pass practically unhindered between media, it is important to perform careful research into what actually happens with the particles during the purification process. Do they pose a risk to natural microorganisms and the natural processes in which they participate? Risks must also be weighed, considering the benefits and the disadvantages of applying a new technology in a particular set of circumstances.

Providing people with healthy, safe drinking water is clearly a priority, therefore it is important to discover and disseminate information about the important details of using the tool.
