The Athens Water Supply & Sewerage Company S.A. (EYDAP) installed the online THM-100™ analyzer to the drinking water reservoir outlet of the Galatsi Water Treatment Plant for a three-month evaluation period, providing EYDAP with continuous online analysis of THM values. The real-time THM data helped EYDAP to understand how the total THM (TTHM) concentration and THM speciation composition are affected by changes in raw source water quality and chlorine contact time. With the help of the reliable data provided by the THM-100, EYDAP was able to better mitigate the presence of harmful THMs across the service area.Read the case study.

The Bilbao Bizkaia Advanced Water Treatment Centre (CATABB) in Etxebarri, Bizkaia, Spain, is an open platform for innovation and research in water treatment that was designed and built by the Bilbao Bizkaia Water Consortium (BBWC) in 2018. To aid CATABB in a study to better understand the adsorption and desorption process of their GAC filters, an online THM-100™ analyzer was installed at the facility to quickly deliver accurate and reliable data on THM levels. According to BBWC, thanks to the online THM-100™ analyzer, staff in the CATABB facility has been able to quickly detect variations in the THMs concentration and have a greater control of the water quality. In addition, the online THM-100™ analyzer has become a very useful tool for current and future research in the study of the generation of disinfection by-products, and it will enable the opening of new lines of research and collaboration at CATABB.Read the case study.
The THM-100™ online THM analyzer has played an important role in Aigües de Barcelona’s compliance and ESG strategy. Since 2014 Aigües de Barcelona has been using real-time THM data from the online THM analyzer to manage disinfection byproducts within its extensive network, minimize energy costs and reduce carbon footprint.Read the case study.
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.Read the case study.
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.Read the case study.
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.Read the case study.
The R.E. Badger Filtration Plant turned to AMS’s online 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.Read the case study.
Aigües de Barcelona decided to monitor THM levels more frequently and they implemented the use of online analyzers to provide accurate and timely information regarding the THM formation in their network.Read the case study.
The Town of Tewksbury, Massachusetts piloted tested an aeration system for additional THM removal. Influent and effluent THM values were measured for the duration of the study using an online THM analyzer.Read the case study.
