Purifying water with waste materials

"Arsenic in drinking water is a huge problem for many

countries around the world: India, China, the U.S., Argentina, Chile, Poland, Hungary and others. In Russia, arsenic-containing regions include the Trans-Baikal, Khabarovsk, Perm, Stavropol, Magadan, Penza regions, Dagestan and Tuva republics," says the project's scientific supervisor Mikhail Khaskelberg, a leading engineer at the Institute of High Technology Physics, TPU.

"Our technology allows any country to find the cheapest material to produce sorbents. This may be Vietnamese sand, corals, waste from the production of bricks, aerated concrete," he adds.

For the experiments in the laboratory, they used a solution in which the arsenic concentration was up to 50 times higher than the maximum levels set by the World Health Organization.

"Scientists in different countries are studying the same corals and sand as sorbents. But we succeeded in making these simple materials work very effectively, using simple and inexpensive processes in terms of future production," says Khaskelberg.
