In the fight to keep water safe and affordable, there is only one technology for the job! SafeGuard™ H2O is a fully automated, on-demand, in-situ generator of stannous (reducing agent) and tin dioxide (adsorbent), coupled with online monitoring capability. SafeGuard H2O removes As, Cr(VI), Cu, Fe, Pb, and Mn from drinking water and As, Cr(VI), Hg & Se from wastewater; acts as corrosion inhibitor for lead pipes and cooling systems; adsorbs SO2, H2S from industrial emissions. Tin and electricity are the only consumables. There are no similar technologies to SafeGuard H2O that integrate a low life-time cost contaminant treatment system with real-time performance controls. With SafeGuard H2O, contaminants have met their match!
