Sand, coral and even waste building materials can become extremely efficient sorbents for water purification from arsenic, if they are treated for this purpose. Scientists have revealed a new technology during experiments. In practice, they succeeded to purify at least 3.6 m3 of water with the help of 200 grams of sorbent from the available raw materials, the cost of which will be a little more than $1 to end consumers. —> Read More
