AMS Installs SafeGuard™ H2O Cr(VI) Remediation Full-Scale Pilot in California

AMS installed a full-scale pilot of its SafeGuard™ H2O intelligent Cr(VI) remediation system in a Central Valley California Community. SafeGuard™ H2O is an innovative technology based on a proprietary approach that generates on demand a stannous ion reagent in-situ via an electrolytic process. The goal of the pilot is to demonstrate the system’s ability to effectively and affordably treat water with elevated Cr(VI) levels to non-detect levels (less than 2 ppb) by converting toxic Cr(VI) to insoluble nontoxic Cr (III), which then can be removed by filtration along with tin dioxide — the product of the conversion. The stannous generator system features automatic dosing and incorporates continuous, real-time monitoring of Cr(VI) levels at the influent and effluent to ensure optimal treatment and compliance with regulatory and operational targets 24/7/365. Through the onboard online analyzer the technology’s ability to effectively reduce Cr(VI) was seen immediately.
