How to convert salt water to drinking water.

When saltwater evaporates it leaves the salt behind. Scientists are turning salt water into the drinking water by using the sustainable solar power. Specially made synthetic membranes are used to filter out large salt particles and impurities so they can be evaporated away and then the rest is heated up vapourised and condensed back into clean 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.

This device easily turns air into water. Turning seawater into drinking water is much more complicated when compared to processing raw freshwater into potable water fit for consumption. 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. 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.

You simply heat the water until it turns to steam then capture the steam. Besides being salty brackish water and seawater are teeming with living dead organic and inorganic particulate matter. And he s managed to do it all from his classroom. Then when the steam condensates on a surface freshwater drips off of that surface into a container.

Yet the most widely used method is still based on the same principle. Heated water evaporates to become water vapor leaving salts and impurities behind and then condenses as it cools to fall as freshwater aka rain. Essentially distillation artificially mimics what occurs in nature. A solar powered system can turn salt water into fresh drinking water for 25 000 people per day.

The water will evaporate but the salt and other impurities won t. The oldest method for converting fresh water from salt water is the distillation process. Salt water is first boiled and then steam is collected and made to pass through the condensing coil. It works well and energy efficient.

The simplest way to do it is the distillation method.
