Autonomous water purification

Around half a billion people worldwide have no access to clean drinking water. As part of the Sowa (short for solar water) focus project, eight students are working on a device that will enable energy-efficient and sustainable treatment of water contaminated with dirt, heavy metals and microorganisms. To ensure that the device functions independently of the electrical grid, it has been equipped with an autonomous control system and draws its energy from solar cells. The system has been designed to fit onto the loading area of a pickup truck for easy transportation.
