A recent demonstration at the City of Banning, California, validated the effectiveness of the AMS SafeGuard™ H2O technology to treat Cr6 and Cr(T) below 10 ppb, granting it conditional acceptance from the California SWRCB Division of Drinking Water for use of the technology by public drinking water systems to treat Cr6 contamination. SafeGuard™ H2O generates a non-toxic stannous reagent on demand via an electrolytic process, offering utilities of all sizes an affordable, effective and sustainable Cr6 remediation solution.

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 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.

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.

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.

The online Instran™ analyzer is integral to maintaining safety in the chlor-alkali process. Instran™ is effective at measuring ammonia and ammonium in brines above 80 g/L; it ensures plant optimization by allowing real-time and accurate monitoring, despite the difficulties presented by a high concentration of NaCl in the sample.

British Petroleum (BP) replaced one of its existing Tytronics online fluoride analyzers at the Castellón refinery in Spain with the online Instran™ Fluoride analyzer. Monitoring fluoride levels in real-time with a reliable and accurate online water quality analyzer is integral to maintaining safety of the alkylation zone and overall refinery. Since its installation in January 2022, the Instran analyzer has been operating continuously and has met the facility’s needs to monitor fluoride levels in real-time within the alkylation zone.

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.
