THM levels in a water treatment system can change rapidly and are highly influenced by changes in raw quality and water age. Without real-time and high-density actual and predictive data on THMs across their networks, water treatment systems face the risks of under-treating their water or incurring substantial costs as a result of over-treatment. When integrated into a disinfection byproduct (DPB) control strategy, the AMS online THM analyzers (THM-100™, THM-100™ FP, THM-RR™) serve as an essential solution to facilitate regulatory compliance with THM standards.

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.

The town of Gilbert, Arizona, has been using real-time THM data from the online THM-100™ analyzer since October 2017 to manage DBPs within its extensive network. The online THM-100 analyzer has acted at the brains of the THM remediation efforts in place across Gilbert’s reservoirs and pumping stations, providing operational certainty that the town did not have before.

Since 2014, the AMS online THM-100™ analyzers gave enabled Aigües de Barcelona to identify rapid changes in water quality in real-time, optimize its treatment processes and reduce related expenses while ensuring THM regulatory compliance. 

In this episode of AMS Talks Value of Data series, Rick Bacon, CEO of AMS, is joined by Grady Eastman, Partner at TwinOxide North America, who discusses the company’s chlorine dioxide treatment solution and its unique demonstration trailer that’s currently making its way across the U.S. visiting with water utilities struggling with THM compliance. Eastman shares insights about how the use of the AMS online THM-100™ THM analyzer has proven a valuable tool enabling TwinOxide to demonstrate the efficacy of their treatment process, helping to resolve THM compliance concerns for municipalities in the US.

SafeGuard™ H2O THM is an intelligent spray aeration system for real-time THM monitoring and control. SafeGuard H2O is a fully automated and consistently reliable THM treatment system that incorporates online, continuous, real-time THM monitoring with active spray aeration to bring utilities a highly accurate and cost-effective solution to meet DBP regulatory compliance and ensure public safety.  SafeGuard H2O is the only THM treatment system to guarantee up to an 80% reduction along with affordable operation for the control of THMs and the ability to understand, in real-time, THM and THM Formation Potential (THM-FP) levels.

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-100™ analyzer, 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 THM and THM Formation Potential monitoring technology was shown to be a viable method to accurately predict THM precursor content and network THM levels. The collaboration was funded by the Massachusetts Clean Energy Center.

Real-time THM data from the online THM-100™ analyzer has helped the City of San Luis Obispo to achieve DBP compliance, optimize their 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 the removal of 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-100™ 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.

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 THMs to support the district’s water treatment process. Douglas shares insights about how the use of the online THM-100™ analyzer has proven a valuable tool enabling BTWD to optimize operations, better understand treatment processes, resolve THM compliance concerns and validate laboratory performance and results.
