Simple water filtration system, invented by three National University of Singapore students
The bag, called Fieldtrate Lite, filters dirty water, such as river water, through a membrane and turns it into potable water in the same time it would take to run it from the tap.
It is the brainchild of Singapore start-up WateROAM, which designs portable water filtration systems for use in disaster relief operations or among rural communities without access to clean water.
