'Super sand' to purify drinking water

Scientists have developed a way to chemically transform ordinary sand into so-called 'super sand' for improved purification of drinking water.

Ordinary sand, an abundant natural resource of the earth, is a preferred filter material used throughout the world to purify drinking water from municipal water supplies to small domestic water filters, particularly as packed bed filters.

The new method transforms the regular sand into a 'super sand' with five times the filtering capacity, according to a report in the journal Applied Materials & Interfaces published by the American Chemical Society (ACS).
