About the solution
So after concluding his PhD in nanotechnology in South Korea he started looking at nano materials that would be suitable for water purification.
The engineer’s innovation absorbs anything from copper and fluoride to bacteria, viruses and pesticides, having the advantage of being more affordable.
According to the inventor, this device should help the 70% of households in Tanzania that do not have clean drinking water.
The product is already trademarked and granted Askwar an award from the UK's Royal Academy of Engineering, worth £25,000.
With this prize the inventor will be able to buy materials in bulk, reducing the production cost.
"For people who cannot afford water filters, we have established water stations where people come and buy water at a very very low, affordable price," he added.
