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

The online THM-100™ monitor provides utilities with continuous high frequency 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.

SafeGuard™ H2O is an advanced on-site, on-demand, automated non-toxic reagent generation system that is advancing the treatment of inorganic and trace metal contaminants and supporting carbon reduction targets by replacing the need to deliver and handle toxic bulk chemicals to treatment plants. The technology helps to remove a wide range of heavy metals and nutrients from water and wastewater as well as inhibit lead, copper and iron corrosion in water transport systems. The novel in-situ process produces reagents at a cost demonstrated to be significantly below that of the same reagents delivered in bulk form. On-site reagent generation is an affordable, non-hazardous and environmentally sustainable solution — providing a 60% cost savings and a rapid return on investment.

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.

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 ferrous reagent in-situ. The technology shows great promise for utilities looking to remove As to low levels and eliminate reliance on hazardous bulk chemicals. Through bench-scale testing and a technology demonstration of this novel system, the City of Alamosa has shown it can achieve arsenic removal below 5 ppb with a ferrous dose of 6.5-8 mg/L.

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.

In December 2022, the State of California published its long-awaited recommendation for a regulatory limit for hexavalent chromium (Cr6) in water of 10 parts per billion. 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.

SafeGuard™ H2O has been thoroughly evaluated and proven to reduce Cr6 to non-detect levels. The technology features an automated treatment design that incorporates real-time online Cr6 monitoring to ensure regulatory standards are met continuously.

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.

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.
