Zero valent iron is increasingly used for in situ chemical reduction of chlorinated solvents and other contaminants and so it is important to understand what to look for in a quality ZVI source.
RAW MATERIAL SOURCES
An important factor in choosing ZVI for environmental remediation is understanding the sources of the original iron.
Reclaimed metal products are available from many sources, and therefore could be contaminated with whatever the material has come in contact with (such as target product or wear parts from machinery blasting).
