The elemental iron nanoparticles (nZVI) efficiently decontaminate the different chlorinated organic compounds, absorb the heavy metals found in the underground water. The technical problem to be solved by the invention is the implementation of a device which ensures the production of a stable, aggregation-free and oxide-free nano-iron, even for the remediation of industrial-scale contamination, and for reducing the storage and transport time of said nano-iron.
