Austin, Texas: Clean drinking water is a major problem around the world, and now a low-cost hydrogel tank can make a liter of river water drinkable in just one hour.
Scientists at the University of Texas at Austin have developed a new hydrogel tablet that can be used to purify one liter of water per hour. River water is not directly drinkable and has to be boiled, graphene filters, chlorine dispensers and other methods are not accessible to every backward population.
Hydrogen does not require energy and costs very little. When it is ready, putting it in a pot kills a large number of bacteria and harmful germs. The pellet enters the water and emits hydrogen peroxide. This activates the carbon particles and kills the bacteria. According to experts, no harmful substances are produced as by-products in this process.
However, it has been tested on a small scale. But it would be very easy to make a hydrogel pillow on a commercial scale. Then these pills can be molded into all shapes and sizes. Experts hope that this revolutionary invention can alleviate the shortage of drinking water in the world and thus make clean water accessible to everyone.
Now a team of scientists has begun work on launching it on a commercial scale.
