OnMaterials recently undertook a study to compare degradation of TCE with 2.0 g/L sulfidized Z-Loy™ AquaMetal ZVI as well as 10.0 g/L of "off-the-shelf" carbonyl iron powder. What we learned is that greater efficacy against chlorinated contaminants is observed with a lesser dose of Z-Loy™ AquaMetal ZVI versus carbonyl iron - In this case, less is more.
|Summary||Z-Loy™ AquaMetal ZVI (sulfidized)||Carbonyl Iron|
