Technology Overview: SafeGuard™ H2O In-situ Reagent Generation

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.

Membrane Technology Conference 2023

Join AMS at the Membrane Technology Conference (MTC23) being held in Knoxville, TN from February 20-23, 2023. Dr. Vladimir Dozortsev will be presenting results from a demonstration of the SafeGuard™ H2O arsenic removal technology on Thursday, February 23, 2023, from 8:15-8:45 am (Session THU01-02). Join us to hear more on “City of Alamosa Evaluates In-Situ Electrogenerated Ferrous Reagent to Replace Bulk Ferric and Support Arsenic Removal”.

City of Alamosa Evaluates In-Situ Electrogenerated Generated Ferrous Reagent to Replace Bulk Ferric and Support Arsenic Removal

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.

Technical Brief: Cost-effective SafeGuard™ H2O Arsenic Removal Technology Paves the Way for More Stringent Federal Arsenic Standards

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.

SafeGuard™ H2O Arsenic Removal Demonstration at California American Water’s Isleton Water System

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 SafeGuardH2O 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).

Isleton, Calif. SafeGuard™ H2O Arsenic Treatment System Demonstration Report

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.

MetalGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, whichever is higher) with a typical measurement time of fewer than 30 minutes. The system also allows for manually collected samples to be analyzed.

MetalGuard™ Lead Alert!™

A novel automated and unattended real-time lead corrosion risk management system for monitoring the risk of exposure to lead contamination.

The analyzer provides rapid analysis of the safety of drinking water in homes, schools, day-cares exposed to the risk of lead contamination. It is designed to be used independently or in conjunction with SafeGuard™ Lead for rapid low-cost analysis of locations predicted to be  at risk for an increase in contamination risk.

SafeGuard™ H2O System Testing for NSF/ANSI 61 Standard

AMS Sr. Product Manager, Vladimir Dozortsev, Ph.D., offers a quick preview of the innovative SafeGuard™ H2O in-situ reagent generation system undergoing testing for NSF/ANSI 61 Standard. A 10 gpm SafeGuard H2O stannous generation system was used in the test. The fully automated system generates a reagent on demand, providing economical and reliable treatment of a wide range of contaminants for small and large water systems.
