Students at the University of Virginia have developed a new way of purifying water that they say could bring improved water quality for millions in the developing world. It’s called a Madi Drop. Field testing begins this month in South Africa.
The lab operates like a kitchen. They add several ingredients. Then they mix, weigh, press and bake them.
What’s created is called a MadiDrop – a ceramic disc infused with silver.
When dropped in water, silver ions, which are atoms that have an electrical charge,, are released to purify the water. And, testing here at the University of Virginia shows clean, safe water.

“Imagine a magic stone and you take this magic stone and you drop it in your water container. It purifies the water and makes it safe to drink. And then imagine that this magic stone only costs a few dollars. That’s what a MadiDrop is,” said Jim Smith, the engineering professor leading the project.
Very good but will it clean the water 99% as nothing in Kali yuga is 100%
So basically, they've invented a portable and easily transported H2O2-infusion-device. Neat :)
It'll only kill bacteria and leave all other impurities of the water intact, though.
Any ideas on the actual lifespan of the "disc"?
KK, your title is misleading (again). The disc does not PURIFY water, it STERILIZES it.
I'm not knocking the POST here, I'm knocking YOU. Your ability to write science-articles properly, is patheticly deficient.
