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.View Resource
While the EPA is reviewing its MCL recommendations for arsenic, utilities are preparing for the possibility of a more stringent federal standard by evaluating the efficacy of their existing arsenic removal treatment systems. Concerned with having to increase their reliance on bulk chemicals to meet a lower arsenic MCL and the associated inherent concerns, the City of Alamosa evaluated the SafeGuard™ H2O technology that generates a ferric regent on-site and on demand. Through bench-scale testing of the in-situ generated ferric reagent, the City of Alamosa has shown it can achieve arsenic removal below 1 ppb while reducing chemical use by more than 30% compared to bulk ferric.View Resource
In search of a reliable and economical treatment solution for Cr6 contamination, the City of Banning undertook a demonstration of the SafeGuard™ H2O in-situ reagent generation system to remove Cr6 down to non-detect levels. The fully automated SafeGuard™ H2O technology uses a certified precursor and an in-situ electrolytic generator to create a non-toxic stannous reagent onsite and on demand. The process is simple, effective, and carbon neutral.View Resource
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.View Resource
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.View Resource
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.View Resource
MetalGuard™ is the first fully automated online trace metals analyzer for monitoring municipal and industrial water and wastewater. The system provides real-time, multi-stream analysis for a range of trace metal contaminants.
MetalGuard delivers accurate and reliable results (up to 1 ppb or ± 15%, whichever is higher) with a typical measurement time of fewer than 30 minutes. The system also allows for manually collected samples to be analyzed.
MetalGuard™ Lead Alert!™
A novel automated and unattended real-time lead corrosion risk management system for monitoring the risk of exposure to lead contamination.
The analyzer provides rapid analysis of the safety of drinking water in homes, schools, day-cares exposed to the risk of lead contamination. It is designed to be used independently or in conjunction with SafeGuard™ Lead for rapid low-cost analysis of locations predicted to be at risk for an increase in contamination risk.
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.View Resource
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.View Resource
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.
