Innovative SafeGuard™ H2O intelligent Cr(VI) treatment system has been successfully demonstrated at the City of Los Banos in California. This novel technology generates a stannous ion reagent in-situ via an electrolytic process and also features an online Cr(VI) monitoring analyzer to ensure remediation of Cr(VI) to below 10 ppb. The technology provides an economical and reliable treatment for water systems affected by contamination from Cr(VI), a known carcinogen.
