In this episode of AMS Talks, Value of Data series, Rick Bacon, CEO of AMS, and Bryan Galvin, President of B&V Enterprises, discuss the challenges and opportunities in managing trihalomethanes (THMs) in drinking water systems and the role of real-time and predicative THM data in designing and operating a highly effective and cost-efficient aeration system. Learn about the operational and process benefits that can be achieved by implementing real-time online THM monitors, such as the AMS online THM analyzer, THM-100™, into your disinfection byproduct mitigation strategy.

A research project collaboration between the Water and Energy Technology Center at the University of Massachusetts in Amherst, Ma., and AMS tested a novel method for near real-time analysis of disinfection byproduct precursors and natural organic matter properties in water supplies. AMS’ online trihalomethane (THM) and THM Formation Potential (THM-FP) monitoring technology was shown to be a viable method to predict THM precursor content and network THM levels accurately. The collaboration was funded by the Massachusetts Clean Energy Center.

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 the fight to keep water safe and affordable, there is only one technology for the job! SafeGuard™ H2O is a fully automated, on-demand, in-situ generator of stannous (reducing agent) and tin dioxide (adsorbent), coupled with online monitoring capability. SafeGuard H2O removes As, Cr(VI), Cu, Fe, Pb, and Mn from drinking water and As, Cr(VI), Hg & Se from wastewater; acts as corrosion inhibitor for lead pipes and cooling systems; adsorbs SO2, H2S from industrial emissions. Tin and electricity are the only consumables. There are no similar technologies to SafeGuard H2O that integrate a low life-time cost contaminant treatment system with real-time performance controls. With SafeGuard H2O, contaminants have met their match!

Real-time trihalomethane (THM) data from the online analyzer, THM-100™, has helped the City of San Luis Obispo to achieve DBP compliance, optimize its aeration process, and ensure public safety. In 2014 and 2015, the City of San Luis Obispo experienced high THM levels and staff began to research processes and practices that could head-off high THM recurrences. To ensure DBP regulatory compliance, the city chose in-tank aeration to mitigate THMs. While effective in removing THMs, in-tank aeration is a high-energy consumption process. Spending approximately $10K per month on power, San Luis Obispo began searching for an effective solution that would help reduce energy expenses while optimizing the treatment process and making it more cost-efficient. The online THM analyzer from AMS was valuable for aeration treatment system design, establishing continuous real-time THM data as vital assets in meeting regulatory compliance and protecting public health.

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.

In this episode of AMS Talks Value of Data series, Rick Bacon, CEO of AMS, is joined by Craig Douglas, P.E., General Manager at the Brunswick & Topsham Water District (BTWD) in Maine, who discusses the importance of real-time monitoring water quality for trihalomethanes (THMs) to support the district’s water treatment process. Douglas shares insights about how using the online THM analyzer,  THM-100™, has proven a valuable tool enabling BTWD to optimize operations, better understand treatment processes, resolve THM compliance concerns and validate laboratory performance and results.
