Method of turning dirty water into clean water of ancient Egyptians

In order to have enough water to live in the desert, the Egyptians thought of a special method of water filtration thousands of years ago.

Learn how to turn dirty water into clean water of ancient Egyptians

Scientists at Pennsylvania State University recently discovered a special water filtration method used by ancient Egyptians thousands of years ago. Accordingly, they used seeds called Moringa oleifera to clean the water. Before the current global clean water problem, this finding could open a new way to save more than 840,000 lives worldwide.

Moringa oleifera tree seeds

Moringa oleifera is a species of angiosperm native to the southern foothills of the Himalayas , they grow fast and can withstand drought, are widely grown in tropical and subtropical regions.

In the rainy season, seeds and leaves are harvested for food. In older studies, tree seeds were known for their water-filtering effects but were not sure about the bactericidal effect . Specifically, the oil extract of the seed is used as flocculation, when put into the water will cause the contaminants to accumulate together and become insoluble particles, which can be filtered to remove.

Water bottles are filtered with seeds of Moringa oleifera

The new study shows that even bacteria will be absorbed as contaminants. When put into the water, the cation dime protein in the seed will concentrate the bacteria together, resolve the cell membrane and cause them to die, then sink to the bottom of the water container.

Scientists from the University of Pennsylvania have collaborated with botanists at Ahmadu Bello University, Nigeria to get the samples and learn more about the potential of this seed. This could be a new resource for farmers because they will have more income, not only to develop Moringa oleifera as food, but they can also establish large plantations to plant seeds.

Although more research is needed to see if 100% of the bacteria can be eliminated, this is an initial success for a method that can be applied to save many lives because the filtered water still exists. in dangerous bacteria .
