This New Technology Change Seawater into Drinking Water

seawater into drinking water

Purify dirty water is a process that is very difficult and expensive, especially in developing countries which just poured a bit of money for this kind of research.

Quoted from the pages of Science Alert, researchers at the University of Alexandria, Egypt developed a purification procedure using a sea water desalination technique called pervaporation, which is able to remove salt from sea water and make it drinkable.

Synthetic membranes are made specifically used to filter out the salt particles and substances or other elements that are large, so that all these elements evaporated, and then the rest heats up, it becomes water vapor, and re-coagulated into clean water.

The membrane can be made in any laboratory using inexpensive materials available in the local area, and the evaporation part of the process does not require electricity. That is, the new method is inexpensive and suitable for areas without regular electricity.

This technique not only allows the ongoing desalination of sea water, but also capable of eliminating waste and elements or other substances. Researchers consisting of several areas of expertise, such as oceanography, chemical engineering, agricultural engineering, biosystem engineering and comes up with a solution. Their work has now been published in the journal Water Science and Technology.

Technology applied in this study is much better than reverse osmosis, the technology currently used in Egypt and most countries of the Middle East and North Africa. This technology allows the desalination of sea water with a high salt concentration as effectively as in the Red Sea, where the cost of desalination is more expensive, but the results are less.

Unfortunately, for those who are waiting for this kind of technology, there is still much work to be done before this technology followed.

Researchers working on the project must prepare trials that prove their theory on a large scale. In addition, there is also the issue of the handling of the waste generated from the process of this technology.

However, such new technologies have a major impact on the lives of millions of people. According to, approximately 750 million people worldwide do not have access to clean drinking water, a problem that caused the death of approximately 840,000 people annually.
