The fully automated SafeGuard™ H2O technology produces a non-toxic stannous reagent onsite and on demand using an in-situ electrolytic generator and a certified precursor. As a cost-effective and efficient solution for municipal and industrial users, SafeGuard™ H2O removes Cr(VI), Fe, H2S, Hg, Pb, and Se from water and wastewater. It also acts as an antibiofilm, antimicrobial reagent for produced water, and as a corrosion inhibitor in distribution networks and cooling systems.
