In Fall 2022, the Joshua Basin Water District demonstrated the SafeGuard™ H2O technology to reduce Cr6 to non-detect levels. SafeGuard H2O proved to be a highly automated process that provided accurate and reliable in-situ stannous 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.

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.

Many industries, hospitals, institutions, and buildings are faced with the inevitable task of managing corrosion and biofilm in their cooling and heating systems. With the SafeGuard™ H2O intelligent corrosion management system these facilities can extend their useful life, reduce maintenance expenditures and foster sustainability. SafeGuard H2O is an innovative electrochemical water treatment solution developed by AMS. A non-toxic and environmentally safe stannous reagent is generated on-site using only tin and electricity and is delivered in a tightly controlled dose. This all-in-one reagent acts as both a biofilm and a corrosion inhibitor. The fully integrated and online SafeGuard H2O treatment approach eliminates the pitfalls of conventional corrosion and biofilm management systems and aids in the delivery of an affordable and reliable process.

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 demonstration with Los Banos confirmed 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.

Semiconductor manufacturing is not only highly dependent on large volumes of water that must be treated to ultrapure standards, but the process also generates significant volumes of wastewater that contains heavy metals and toxic solvents. To reduce its environmental impact, the semiconductor industry is actively searching for new ways to optimize water consumption and improve the quality of wastewater effluent. AMS offers innovative online real-time, continuous trace metals monitoring solutions designed to aid the semiconductor industry in optimizing water consumption, improving the quality of wastewater effluent and reducing its environmental impact.

Faced with high IEX process waste disposal costs, TRUMPF, a manufacturer of laser diodes made from Gallium Arsenide substrates (GaAs) wafers, undertook efforts to optimize the IEX process and produce less hazardous waste. One of the process improvements included the installation of the MetalGuard Arsenic online arsenic analyzer to continuously measure influent and effluent arsenic levels in real-time, providing TRUMPF with a stream of accurate and reliable arsenic data to measure the performance of its IEX system and ensure regulatory compliance. Timely and accurate arsenic results enabled TRUMPF to optimize rinse water reuse as well as to optimize and reduce IEX backwash frequencies, increasing media performance and reducing hazardous waste generation. These process improvements have resulted in an estimated annual cost savings of $100K for the facility.

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. 

As regulatory requirements and the availability of more accurate diagnostic technologies continue to push the legal threshold limit of contaminants, utilities are turning to high-frequency data to identify contaminant threats and diagnose critical treatment system performance.
