SafeGuard™ H2O is an advanced on-site, on-demand, automated non-toxic reagent generation system that is advancing the treatment of inorganic and trace metal contaminants and supporting carbon reduction targets by replacing the need to deliver and handle toxic bulk chemicals to treatment plants. The technology helps to remove a wide range of heavy metals and nutrients from water and wastewater as well as inhibit lead, copper and iron corrosion in water transport systems. The novel in-situ process produces reagents at a cost demonstrated to be significantly below that of the same reagents delivered in bulk form. On-site reagent generation is an affordable, non-hazardous and environmentally sustainable solution — providing a 60% cost savings and a rapid return on investment.

While the EPA is reviewing its MCL recommendations for arsenic, utilities are preparing for the possibility of a more stringent federal standard by evaluating the efficacy of their existing arsenic removal treatment systems. Concerned with having to increase their reliance on bulk chemicals to meet a lower arsenic MCL and the associated inherent concerns, the City of Alamosa evaluated the SafeGuard™ H2O technology that generates a ferrous reagent in-situ. The technology shows great promise for utilities looking to remove As to low levels and eliminate reliance on hazardous bulk chemicals. Through bench-scale testing and a technology demonstration of this novel system, the City of Alamosa has shown it can achieve arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L.

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 the Fall of 2022, the Joshua Basin Water District undertook a demonstration of the SafeGuard™ H2O technology to reduce Cr6 down to non-detect levels. SafeGuard H2O proved to be a highly automated process that provided accurate and reliable in-situ reagent generation to reduce Cr6 to below 1 ppb. The capability of SafeGuard H2O to consistently remove Cr6 to non-detect levels creates the opportunity for Joshua Basin Water District and other utilities to blend water from Cr6-contaminated wells and achieve overall system compliance. With SafeGuard H2O, the capital cost of bringing a system into Cr6 compliance can be mitigated by eliminating the need for treatment at all wells.

In search of a reliable and economical treatment solution for Cr6 contamination, the City of Banning undertook a demonstration of the SafeGuard™ H2O in-situ reagent generation system to remove Cr6 down to non-detect levels. The fully automated SafeGuard™ H2O technology uses a certified precursor and an in-situ electrolytic generator to create a non-toxic stannous reagent onsite and on demand. The process is simple, effective, and carbon neutral.

AMS and NCS Engineers have teamed up to bring a demonstration of the SafeGuard™ H2O in-situ reagent generation system for the removal of Cr6 to the City of Banning. The 3-gpm technology demonstration reveals how the fully automated SafeGuard™ H2O system addresses the needs of small, underserved communities impacted by Cr6 contamination by providing an affordable, non-hazardous and environmentally sustainable remediation solution.

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.

California American Water’s Isleton Water System underwent an evaluation of SafeGuard™ H2O, an intelligent arsenic remediation system manufactured by AMS. This innovative technology generates a ferrous ion reagent in-situ via an electrolytic process to address arsenic contamination. The objective of the project was to demonstrate the ability of the electrogenerated ferrous reagent produced on demand by the SafeGuard™ H2O system to remove arsenic from unchlorinated well water reliably and effectively. The SafeGuard™ H2O system consistently treated arsenic below 10 ppb and the technology’s modular design can be easily integrated with the facility’s existing coagulation/filtration system; replacing the use of liquid ferric chloride and providing the facility with operational and capital savings.

Communities across the world are plagued by lead contamination and corrosion concerns, which often come to light during testing of children’s blood and after the event has occurred. AMS has developed advanced solutions for lead corrosion risk management and control. AMS’ online lead corrosion monitoring technologies are backed by actionable, high-frequency data, providing a comprehensive risk map that informs public health authorities, water treatment plant operators and consumers. AMS’ intelligent in-situ corrosion inhibitor generation and delivery technology offers a localized treatment solution that displaces orthophosphates and provides a responsive, point-of-care, effective approach to manage the multi-variant challenge of lead corrosion risk.
