University of South Florida researchers found the best pure water on the prickly pear cactus. Inhabitants of this desert is very effective in transporting sediment and bacteria from dirty water and the good news of this plant can live in the world.
This is not the first research found that the ability of cactus plants. Mexican community in the 19th century using a cactus as a device for purifying water. Thick layer of resin on the cactus that save water, is a part which is responsible for purifying water.
Researchers then extract the sap and added into the dirty water because of sediment and bacteria.Sediment and bacteria cause the sap to join, then settles on the bottom and separates 98% of bacteria in the water.
Researchers looked at communities in developing countries using a cactus in their daily lives. They used to poach a piece of cactus to get the sap, the sap is then added to the water, just as did the investigators.
However, there are still hurdles to be overcome. Resources need to be prepared to develop the spread of cactus and how to convince the community that has been filtered water is completely free of bacteria.
If some of these problems can be solved, it is cheap and clean water that can reach millions of people who lack these resources.
