Step2O- Clean Water for Life- Xylem

Placeholder Show Content


Xylem Inc. believes in pushing the designs of their products to achieve higher performance, longer life, better usability and cost-effectiveness. The student team which includes students from Stanford University, USA and Aalto University, Finland were asked to come up with a solution to improve the transportation or filtering of water with inspiration from nature. After multiple iterations and prototypes, the team came up with a solution to harness the mechanical energy dissipated by user footfall to power a low cost, easily maintainable filtration system which would be able to remove sediments, pathogens, and heavy metals. The sediments and pathogens would be filtered out with commercially available filters and the heavy metals would be filtered by algae by the process of bio-adsorption.
