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.

The Pima County Regional Wastewater Reclamation Department in Arizona, is using the THM-100™ online THM analyzer to continuously, accurately and reliability monitor THM values in real-time at its Tres Rios Water Reclamation Facility.

Currently, the EPA is reviewing its MCL recommendations for arsenic since technological advancements such as the SafeGuard™ H2O now make it possible to economically treat to levels of 5 ppb and lower. SafeGuard™ H2O is proven to eliminate arsenic and drastically reduce the cost of removing this toxic contaminant from drinking water supplies. The SafeGuard™ H2O arsenic treatment system generates a ferric reagent in-situ through a simple, effective and sustainable process.

In the Fall of 2022, the Joshua Basin Water District undertook a demonstration of the SafeGuard™ H2O technology to reduce Cr6 down to non-detect levels. SafeGuard H2O proved to be a highly automated process that provided accurate and reliable in-situ reagent generation to reduce Cr6 to below 1 ppb. The capability of SafeGuard H2O to consistently remove Cr6 to non-detect levels creates the opportunity for Joshua Basin Water District and other utilities to blend water from Cr6-contaminated wells and achieve overall system compliance. With SafeGuard H2O, the capital cost of bringing a system into Cr6 compliance can be mitigated by eliminating the need for treatment at all wells.

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.

SafeGuard™ H2O is an innovative arsenic treatment approach that generates a ferrous ion reagent in-situ via an electrolytic process to address arsenic contamination effectively and economically. The demonstration of SafeGuard™ H2O at California American Water’s Isleton Water System proved the effectiveness of the technology to mitigate total arsenic contamination in drinking water below 10 ppb, and its ability to deliver an affordable and reliable fully automated treatment process that does not require the use of bulk chemicals like conventional treatment approaches.

California American Water’s Isleton Water System underwent an evaluation of SafeGuard™ H2O, an intelligent arsenic remediation system manufactured by AMS. This innovative technology generates a ferrous ion reagent in-situ via an electrolytic process to address arsenic contamination. The objective of the project was to demonstrate the ability of the electrogenerated ferrous reagent produced on demand by the SafeGuard™ H2O system to remove arsenic from unchlorinated well water reliably and effectively. The SafeGuard™ H2O system consistently treated arsenic below 10 ppb and the technology’s modular design can be easily integrated with the facility’s existing coagulation/filtration system; replacing the use of liquid ferric chloride and providing the facility with operational and capital savings.

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. 

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.
