The Lead and Copper Rule Improvements (LCRI) regulation will rely more heavily on using lead and copper testing and monitoring apparatuses. These apparatuses have issues around sampling constraints and lack real-time data on water corrosivity to anticipate the risk of lead/copper corrosion before it happens in homes/schools/daycares. This is where the benefit of real-time lead and copper monitoring in drinking water systems can significantly contribute to a water system’s compliance with the proposed lead and copper action levels outlined in the LCRI. The automatic, unattended online MetalGuard™ analyzer from AMS provides high-frequency, timely, and accurate predictive data to stakeholders on their exposure to lead or copper contamination risks.

In this episode of AMS Talks, Industry Consultant Nadia Abboud speaks with AMS Senior Product Manager Vladimir Dozortsev, Ph.D., about the evolution of the SafeGuard™ H2O technology into new markets and applications by expanding into the on-site generation of a strong iron-based oxidizing reagent. The reagent can be used to treat a range of contaminants across municipal and industrial applications, including food and beverage, mining, oil and gas, pharmaceutical, and semiconductor. SafeGuard™ H2O provides sustainable, cost-effective and reliable water and wastewater treatment for facilities seeking environmentally friendly solutions that also reduce their reliance on bulk chemicals.

For more than a decade, the Brunswick & Topsham Water District (BTWD) in Maine has been using the AMS THM-100™ online THM analyzer to help manage THM concerns. Over the years, the online THM analyzer has been proven a valuable tool for the utility, enabling it to better understand its treatment processes and optimize operations. In this episode of AMS Talks, Craig Douglas, P.E., General Manager at BTWD, discusses the district’s unconventional THM management journey and how the real-time data from the THM-100™ analyzer opened the utility staff’s eyes to the impact of the operational decisions they were making.

In this episode of AMS Talks, Industry Consultant Nadia Abboud speaks with Rick Bacon, CEO of Aqua Metrology Systems (AMS), about the significance and impact of the company’s recent achievements and award recognitions. First, AMS was selected by Sacyr iChallenges for its open innovation programs as one of the three companies appointed as Sacyr’s global partner for online water quality monitoring. In addition, it was recently announced that AMS was chosen as the North & Northwest Breakthrough Winner of The Spectator Economic Innovator of the Year Award in partnership with Investec.

With increasing concerns about the quality of bulk reagents such as bulk ferric chemicals that are widely used in the water treatment industry, utilities are seeking alternative, more carbon neutral, and environmentally friendly treatment methods. AMS’ SafeGuard™ H2O technology is a sustainable alternative that responds to that need. SafeGuard™ H2O has numerous advantages over traditional coagulation processes that depend on bulk ferric chloride. The system’s on-site generation of a ferrous/ferric reagent requires a smaller footprint, and it offers greater reliability to utilities looking to reduce GHG emissions. SafeGuard™ H2O also has a 30 – 50% lifetime cost advantage, considering the cost of purchasing bulk chemicals, manual process supervision, and waste disposal. SafeGuard™ H2O is poised to replace the use of hazardous bulk reagents since it does not compromise the quality of drinking water, harm the environment and it can be produced using renewable energy sources and stored for later use when these are unavailable.

SafeGuard™ H2O is a proven solution for utilities looking to reduce GHG emissions and remove hydrogen sulfide (H2S) to non-detect levels while lowering the cost of treatment (energy and operation). SafeGuard™ H2O can be powered by renewable energy, and tin sulfide, a valuable resource to multiple industries, can be recovered from the process. As a low-carbon approach to H2S removal, SafeGuard™ H2O has achieved 100% removal of H2S from reverse osmosis treated water and raw water supplies.

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 recent demonstration at the City of Banning, California, validated the effectiveness of the AMS 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. SafeGuard™ H2O generates a non-toxic stannous reagent on demand via an electrolytic process, offering utilities of all sizes an affordable, effective and sustainable Cr6 remediation solution.
