Scientists from the Nanotechnology Research Institute in Prague, Czechoslovakia, have developed a technology that cleans “dead” water and turns it into drinking water. The new method uses a 3-dimensional membrane to clean the water, which is sour, contains harmful toxins and lacks oxygen in its original state. Institute head Petr Carvan said, “From a total contaminate, which could hardly be called water, we’ve managed to produce drinking water without any additional elements, without bacteria, water that is silk, soft and re-mineralised.” The scientists are also able, on a client’s request, to add minerals such as iodide, fluorine, magnesium, manganese and calcium to the cleaned water so that it is suitable to drink. According to Carvan, “We’ve scored world success with this technology,” adding that delegations from all over the world have come to Prague to see the unique prototype of this water treatment device. It can clean up to 10 cubic meters of water in 24 hours with 95 percent effectiveness, and is relatively cheap to operate. “The Vietnamese have turned to us already. They want to clean the Mekong river,” said Carvan.
