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.

The City of Alamosa, Colorado, evaluated the SafeGuard™ H2O arsenic removal technology to replace the use of bulk ferric chloride. The evaluation demonstrated the technology’s ability to provide effective and reliable arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L that was generated on-site and on-demand. The demonstration also evaluated the purity of the in-situ electrogenerated ferrous reagent compared to bulk ferric chloride, showing SafeGuard™ H2O’s ferrous reagent precursor to be of higher quality. In this episode of AMS Talks, Industry Consultant Nadia Abboud speaks with Roy Sanchez, CWP, Water Plant Operator for the City of Alamosa, and Dr. Vladimir Dozortsev, Senior Product Manager for AMS, who discuss insights about this project and what prompted the City of Alamosa to undertake this arsenic removal demonstration.

Ferric chloride is a water treatment chemical widely used to remove impurities in water and wastewater. While ferric chloride is effective and approved for use in a range of applications, there is a lack of adequate quality controls and certification for this bulk chemical. Ferric chloride contains a range of contaminants, including manganese, chromium, arsenic, zinc, lead, and copper that can be found in high concentrations and can be very harmful to human health. In addition, ferric chloride is an extremely corrosive and potentially hazardous substance that requires it to be handled and stored with care, driving the cost of treatment. In this episode of AMS Talks, Rick Bacon, CEO of AMS, and Industry Consultant Nadia Abboud discuss the use of ferric chloride as a water treatment chemical, and the need for alternative solutions that do not contaminate our water supply.

Concerned with its reliance on bulk chemicals to meet the current or future arsenic MCL, the City of Alamosa evaluated the SafeGuard™ H2O arsenic removal treatment system to replace the use of bulk ferric chloride. The bench-scale test characterized the efficacy of the technology and the coagulation filtration requirements. The demonstration was initiated to show the ability of SafeGuard™ H2O to provide effective and reliable arsenic removal below the MCL, evaluate the purity of the in-situ generated ferrous reagent compared to bulk ferric chloride, and study the impact of both reagents on UF membrane health.

The SafeGuard™ H2O arsenic removal treatment system has been evaluated by the City of Alamosa to replace the use of bulk ferric chloride. The evaluation was completed via bench-scale testing and subsequent pilot demonstration; showing the electrogenerated ferrous reagent to achieve reliable arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L. The validation of SafeGuard™ H2O technology to generate a ferrous reagent in-situ via an electrolytic process shows great promise for utilities looking to remove arsenic to low levels and eliminate reliance on hazardous bulk chemicals.

Currently, the EPA is reviewing its MCL recommendations for arsenic since technological advancements such as the SafeGuard™ H2O now make it possible to economically treat to levels of 5 ppb and lower. SafeGuard™ H2O is proven to eliminate arsenic and drastically reduce the cost of removing this toxic contaminant from drinking water supplies. The SafeGuard™ H2O arsenic treatment system generates a ferric reagent in-situ through a simple, effective and sustainable process.

In this episode of AMS Talks, Rick Bacon, CEO of AMS, speaks with Joshua Webster, water treatment operator for California American Water about the demonstration of SafeGuard™ H2O arsenic removal technology at the Isleton Water System. The demonstration at Isleton showed the effectiveness of SafeGuard™ H2O to mitigate total arsenic contamination in drinking water below 10 ppb, and its ability to deliver an affordable and reliable fully automated treatment process that does not require the use of bulk chemicals like conventional treatment approaches (e.g., coagulation/filtration).

SafeGuard™ H2O is an innovative arsenic treatment approach that generates a ferrous ion reagent in-situ via an electrolytic process to address arsenic contamination effectively and economically. The demonstration of SafeGuard™ H2O at California American Water’s Isleton Water System proved the effectiveness of the technology to mitigate total arsenic contamination in drinking water below 10 ppb, and its ability to deliver an affordable and reliable fully automated treatment process that does not require the use of bulk chemicals like conventional treatment approaches.
