In the latest episode of AMS Talks, Abigail Cantor, P.E., Chemical Engineer at Process Research Solutions LLC. discusses a collaboration project with Madison Water Utility to evaluate real-time monitoring of lead and copper in drinking water. This project is particularly timely given the recent EPA proposal to update regulations for reducing lead and copper exposure through drinking water. The proposed regulation will rely more heavily on using lead and copper monitoring and testing apparatuses that have historically lacked real-time data on water corrosivity, crucial for managing fluctuating lead and copper levels in water. Cantor outlines an innovative testing apparatus approach that mimics residential plumbing and incorporates automated online AMS MetalGuard™  lead and copper monitors to provide more frequent and real-time analysis. Utilities looking to adopt a cutting-edge monitoring and testing approach for lead and copper in drinking water systems will not want to miss this interview.

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 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.

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.

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.

MetalGuard™ is a fully automated online trace metals analyzer for monitoring municipal and industrial water and wastewater. This intelligent system serves as an essential element to ensure regulatory compliance and process control. MetalGuard provides real-time, multi-stream analysis for a range of trace metal contaminants; delivering accurate and reliable results in less than 30 minutes.

Southsea STS, a U.K.-based technical services company specializing in water quality, has a history of embracing and implementing new technologies and ideas to support compliance and control in buildings. Recently, Southsea has been evaluating new technologies for corrosion management as part of a pilot program with the Institution of Civil Engineers (ICE) in the UK. Richard Lawson, Director for Southsea STS, gives a behind the scenes look of the pilot project on the use of AMS’ SafeGuard™ H2O stannous generator to provide corrosion inhibition water treatment for closed-loop heating and cooling systems. Current corrosion inhibitors are relatively expensive, potentially toxic to handle, and can have difficulty meeting requirements imposed for disposal. The SafeGuard™ H2O stannous-based solution can help organizations better manage corrosion and ensure compliance.

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.

In this episode of AMS Talks, Rick Bacon, CEO of Aqua Metrology Systems, and Richard Lawson, Director of Southsea STS, discuss the “Value of Data for Corrosion Control.” Lawson addresses the challenges associated with managing corrosion in buildings and the value of data-driven solutions to better manage and control these water systems and ensure compliance.
