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 trihalomethane (THM) values. The real-time THM data helped EYDAP understand how changes in raw source water quality and chlorine contact time affect the total THM (TTHM) concentration and THM speciation composition. With the help of the reliable data provided by the THM-100, EYDAP was able to mitigate better the presence of harmful THMs across the service area.

Approximately 50% of water and wastewater utilities experience delays in chemical availability due to supply chain disruptions. According to McKinsey & Company’s January 2023 Chemicals Practice Insight “A new operations formula for the chemicals sector,” 2022 was a tumultuous year for the global chemical sector which faced spiraling costs, looming skills shortage, and pressure for decarbonization. So, what does this all mean for the water industry? In this episode of AMS Talks AMS CEO Rick Bacon and Industry Consultant Nadia Abboud discuss critical chemical supply chain risk and explore solutions to help mitigate exposure to those risks in the water industry.

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 trihalomethane (THM) analyzer, THM-100™, was installed at the facility to deliver accurate and reliable data on THM levels quickly. According to BBWC, thanks to the online THM analyzer, staff in the CATABB facility has been able to detect variations in the THMs concentration quickly and have greater control of the water quality. In addition, the online THM 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.

AMS is at forefront of digitalization in the water sector. AMS enters 2023 with several significant achievements in 2022 that position it for a broad-based and robust growth of its AMS Analytics and AMS Environment divisions in 2023 and beyond. In this exclusive piece “Driving Digitalization in the Water Sector to Transform the Way We Treat Water,” Rick Bacon, CEO of AMS, shares how AMS is helping transform the way we treat water by providing facilities with proven solutions that will improve their energy efficiency and help them control their GHG emissions.

In December 2022, the State of California published its long-awaited recommendation for a regulatory limit for hexavalent chromium (Cr6) in water of 10 ppb. According to the California State Water Resources Control Board, there are more than 2,600 community systems with elevated Cr6 levels serving nearly 13 million people. This proposed regulation unequivocally identifies AMS and its in-situ stannous generation technology, SafeGuard™ H2O, as the best available technology to treat Cr6 and provide safe drinking water to the millions of consumers across California, many of whom live in underserved communities. Watch the latest episode of AMS Talks featuring AMS CEO Rick Bacon and Industry Consultant Nadia Abboud who discuss how this proven and cost-effective solution can treat most of the wells with high Cr6 levels, giving a peace of mind to water utilities impacted by this new regulation.

Facilities can enhance their data quality assurance program by remotely monitoring the health of their water quality instruments with SafeGuard™ Sentinel. This innovative technology delivers cloud monitoring for Modbus-enabled instruments, providing facilities with accurate and reliable 24/7/365 conditional monitoring data for water and wastewater management industrywide.

The Pima County Regional Wastewater Reclamation Department in Arizona uses the THM-100™ online trihalomethane (THM) analyzer to continuously, accurately, and reliably 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 treat to levels of 5 ppb and lower economically. 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 Fall 2022, the Joshua Basin Water District demonstrated the SafeGuard™ H2O technology to reduce Cr6 to non-detect levels. SafeGuard H2O proved to be a highly automated process that provided accurate and reliable in-situ stannous 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.
