Can We Turn Seawater Into Drinking Water

Developed by a team of researchers at alexandria university in egypt the procedure uses a desalination technique called pervaporation to remove the salt from sea water and make it drinkable.

Can we turn seawater into drinking water.

Then cover the bowl with plastic wrap and set a rock on top of the plastic wrap over the cup which will make a dip so fresh water can drip into the cup. The simple hurdle that must be overcome to turn seawater into freshwater is to remove the dissolved salt in seawater. Desalination plants turn seawater into drinking water but also pump hypersaline water back into the environment. To turn saltwater into drinking water start by pouring the saltwater into a bowl and placing a small cup in the center of the water.

A solar powered system can turn salt water into fresh drinking water for 25 000 people per day. So why can t we convert seawater into drinking water. The handheld seawater desalination device is capable of producing more than two liters of fresh drinking water from seawater within an hour through a system of osmosis membranes. Actually we can and we do.

Making sea water into drinking water requires removal of the dissolved salt that according to the u s. That water is filtered for bigger contaminants and some essential tiny sea creatures before it is sent through a reverse osmosis system that pressurizes the water through membranes separating. It could help address the world s looming water crisis. That s especially troubling because desal has become extremely popular.

Geological survey makes up approximately 35 000 parts per million ppm of sea water s chemical composition. In fact people have been making seawater drinkable at least as far back as the ancient greeks.
