Nanoparticles of metallic iron for ground water treatment (review of foreign publications)

Summary

The international experience in using the technology of ground water treatment with the help of nanoparticles of metallic iron is presented. The technology of injecting nanoparticles provides for their transfer through intake wells practically to any point at any depth of the ground water basin. Limitations are imposed exclusively by economic factors. The well number and placing are determined by geologic and geochemical characteristics of the polluted area subject to investigation. Prior to the implementation of a project studies shall be carried out to specify the required composition and concentration of iron particle suspension, injection equipment, well placing and depth, working pressure and consumption of the suspended matter, duration of treatment.
