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

Since 2014, the AMS online trihalomethane (THM) analyzer, THM-100™, has 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. 

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.

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.

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.

The R.E. Badger Filtration Plant turned to AMS’s online trihalomethane (THM) analyzer, THM-100™, to obtain continuous and real-time data to characterize THMs in the distribution system and allow it to have an early indication of potential THM formation problems before they become a compliance issue.

The rapid response benchtop THM-RR™ analyzer provides fast, reliable and accurate analysis of individual and total THM concentrations. For water treatment operators, consulting engineers and THM treatment system vendors the THM-RR delivers valuable THM performance data far faster than external laboratories.

Aqua Metrology Systems has partnered with Foundation Instruments, Inc. to expand its offerings of online and real-time monitoring of trihalomethanes (THMs) with the addition of Foundation Instruments’ THM-Rapid Response (THM-RR) online benchtop analyzer. The benchtop analyzer reports individual and total THM concentrations in real‐time so that utilities can be more proactive in responding to water quality changes and managing carcinogenic disinfection by-products (DBP).

Intelligent water treatment systems incorporate real-time sensing to ensure that their performance is optimized to avoid under- or over-treatment and that any deterioration in system performance is signaled to permit timely remedial intervention.

Aqua Metrology Systems and University of Massachusetts Amherst (UMass Amherst), have partnered to develop a robust online raw-water trihalomethanes (THMs) -precursor analyzer. On 23 January 2018 they received a commitment from Massachusetts Clean Energy Center (MassCEC) through its AmplifyMass program to cost share in the development and assessment of this new online THM-Precursor analyzer.
