2.2 billion people worldwide — more than a quarter of the world’s population — do not have safe access to safe drinking water, according to the latest UNESCO World Water Resources Development Report. In Brazil, this reality affects around 33 million inhabitants, which draws even more attention when one takes into account the fact that the country is home to the largest freshwater reserve on the planet.
It was in this scenario of water scarcity and inequality that the Brazilian startup PWTech developed, in partnership with the Federal University of São Carlos (UFSCar) and the University of São Paulo (USP), a sustainable, portable, low-cost and easy-to-use technology. use, capable of purifying up to 5 thousand liters of water per day: the PW 5660, a device that works like a mini treatment plant and can make contaminated water from rivers, wells, dams, dams, lakes and even rain drinkable.
