ETH student develops filter for clean water around the world
Date:7/23/2014

facturing process that shows great potential. It has been used in a wide range of other applications since then for example, in a non-toxic outdoor jacket (as reported in ETH News) and its use as a battery separator is also being investigated.

First filters to Africa next January

A year ago, Nussbaumer learned of the project to further develop this membrane for use in a water filter. The mechanical engineering student was so enthusiastic about the idea that after completing his bachelor's degree, he decided to postpone his master's degree for a year in order to devote himself to this project. "I was really looking forward to finally being able to do something tangible and useful. Of course, we hoped that the membrane would prove suitable for a water filter, but we never expected such excellent test results," says Nussbaumer proudly.

In order that the research team can manufacture enough filters to use in developing countries, they are looking for financial support. They will use the proceeds to purchase the tools they need to manufacture the filters. "As for what is left over, we will use 80% to produce the filter and transport it to Africa and 20% to further develop the concept," says Nussbaumer. They expect to have the first filters completed in January 2015; they will be sent to project supporters and to Africa for use in a test phase.

Perfect for travellers and Walkers

It is still not certain whether DrinkPure will be available in future in retail stores. Alongside its suitability for development aid, the device is also perfect for travellers and walkers. "Quickly screw it on a bottle and you can take a drink from any pond or river without a second thought," explains Nussbaumer. "I'm actually not a serious walker myself, but if I were to go I would be sure to take the filter along."
