A team of all-Italian engineers from the Polytechnic University of Turin has studied a revolutionary system for desalting seawater. This device has been designed to handle up to 20 liters of drinking water for every meter of surface exposed to the sun. A possible solution to the water crisis announced by the FAO by 2025, which could affect two billion people.
A group of scientists from the Polytechnic University of Turin has created a seawater desalination system inspired by mangroves. These are the conditions for suspicious waters on the water, they are able to take the necessary nutrients from salt water thanks to a special membrane that divides it from the sweet one. The system is based on this natural mechanism, the contaminated water does not mix with the purified water.
The sustainability of nature, the judgment was designed by an ecological and economic system that could face the water crisis predicted by the FAO by 2025. The device was also designed to grow on its surface, this will allow the creation of floating gardens in those places poor in water resources and infrastructure.
But come on stage this invention? The first is apparently simple: in practice, water is collected through a porous material like a sponge, without the aid of expensive and cumbersome devices such as pumps. The solar energy heats the water and evaporates it by depositing the sale, here come into play the membranes inspired by the mangroves that prevent condensed water from reuniting with salt.
The most innovative thing is the "passive" system, based entirely on natural phenomena. This device was designed in 20 minutes of space in a day for each meter of surface exposed to the sun. The team of engineers working on this project is part of the Clean Water Center, an interdepartmental center of the Polytechnic which is currently still looking for partners to develop the prototype in the field.
