A SafeGuard™ H2O demonstration system with a capacity of 3 gpm (150 mL/minute) was installed onsite for testing at the City of Banning’s Facility Well C2 from June-September 2022. The scope of this demonstration focused on the safe, reliable reduction of Cr6 to Cr3 using SafeGuard™ H2O electrogenerated stannous reagent.  The demonstration validated the effectiveness of the SafeGuard™ H2O technology to treat Cr6 and Cr(T) below 10 ppb, granting it conditional acceptance from the California SWRCB Division of Drinking Water for use of the technology by public drinking water systems to treat Cr6 contamination.

A SafeGuard™ H2O intelligent Cr(VI) remediation system demonstration unit with a treatment capacity of 10 gpm was installed with the City of Los Banos, California to evaluate the performance of the technology to treat Cr(VI) to non-detect levels (under 1 ppb) in unchlorinated well water.  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 pilot with Los Banos provided confirmation of the technology’s efficacy and third-party validation of the SafeGuard H2O system as a cost-effective alternative to traditional Cr(VI) treatment systems. Results are detailed.

AMS is committed to bringing intelligent water remediation solutions that can be fully controlled, monitored and optimized remotely, while ensuring that these systems are more accessible to a wider sector of the population through affordable financial models. As such, AMS has offered an official response to a white paper — “Economic Feasibility Analysis in Consideration of a Hexavalent Chromium MCL” — published by the California State Water Board (SWB), who is engaged in a process of consultation to determine at what level the regulatory limit for Cr(VI) should be set. AMS’ position on Cr(VI) regulation and comments to SWB are summarized in this technical brief.

California American Water turned to AMS’s MetalGuard™ fully-automated, online multi-stream Cr(VI) analyzer to have higher visibility of Cr(VI) contaminant levels in real-time and allow them to better monitor and address critical steps in their remediation process. 

Intelligent water treatment systems incorporate real-time sensing to ensure that their performance is optimized to avoid under- or over-treatment and that any deterioration in system performance is signaled to permit timely remedial intervention.

Real-time data and analytical information from online instruments help utilities comply with water quality regulations. The complete article detailing how online water quality instruments are poised for growth was published in the March/April 2015 issue of World Water.
