Concerned with its reliance on bulk chemicals to meet the current or future arsenic MCL, the City of Alamosa evaluated the SafeGuard™ H2O arsenic removal treatment system to replace the use of bulk ferric chloride. The bench-scale test characterized the efficacy of the technology and the coagulation filtration requirements. The demonstration was initiated to show the ability of SafeGuard™ H2O to provide effective and reliable arsenic removal below the MCL, evaluate the purity of the in-situ generated ferrous reagent compared to bulk ferric chloride, and study the impact of both reagents on UF membrane health.

The SafeGuard™ H2O arsenic removal treatment system has been evaluated by the City of Alamosa to replace the use of bulk ferric chloride. The evaluation was completed via bench-scale testing and subsequent pilot demonstration; showing the electrogenerated ferrous reagent to achieve reliable arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L. The validation of SafeGuard™ H2O technology to generate a ferrous reagent in-situ via an electrolytic process shows great promise for utilities looking to remove arsenic to low levels and eliminate reliance on hazardous bulk chemicals.

AMS and BIOBOX announce their partnership which brings to United States BIOBOX’s containerized biological treatment system for nitrate removal from groundwater and wastewater. The partnership will offer a fully automated, turnkey “intelligent nitrate treatment system” by integrating AMS’ online Instran™ nitrate analyzer that provides continuous, real-time control of the system performance

Real-time insights and innovative water treatment technologies can minimize the environmental impact of water and wastewater treatment. Specifically, the AMS’ SafeGuard™ H2O technology, which generates ferrous or stannous-based water treatment reagents on-site and on-demand, coupled with real-time monitoring, can reduce the need for bulk toxic chemicals and displace traditional treatment technologies, significantly reducing emissions.

The online THM-100™ monitor provides utilities with continuous high-frequency trihalomethane (THM) and THM formation potential (THM-FP) data in real-time. With the help of the THM-100™, utilities can design cost-effective THM treatment systems, optimize their water or wastewater treatment process and reduce related expenses while ensuring compliance with regulatory standards for THMs.

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.
