Report: Detecting Low-Level of THMs in Treated Wastewater Using Online THM Monitor

The City of Paso Robles, California, used an online water quality instrument to characterize and monitor low levels of bromodichloromethane (BDCM) and dibromochloromethane (DBCM) in its treated wastewater for groundwater recharge (GWR) use. The high frequency of reliable and accurate THM data provided by the online instrument proved essential to the City’s disinfection by-product (DBP) strategy to obtain regulatory compliance with NPDES permit levels.

Report: The Power of Ferrate(VI)

The potential of ferrate, specifically Ferrate(VI), a supercharged form of iron with a +6 oxidation state, as an advanced oxidant for water and wastewater treatment is widely documented. While the use of ferrates has been limited due to synthesis difficulties and inherent instability, AMS has developed a novel system for on-site production of Ferrate(VI) to address this limitation. Examining the history of oxidation in water treatment and the role of advanced oxidation processes (AOPs) in oxidizing complex organic constituents, it is evident that Ferrate(VI) can be a strong oxidant with a higher oxidation potential than ozone and chlorine. Despite challenges in treating stubborn organics and the need for efficient and economical AOPs, ongoing study and consideration for Ferrate as an AOP option will reshape the paradigm of advanced oxidation for water and wastewater treatment.

Viewpoints: Hexavalent Chromium Removal, Future-Proof Your Technology Investment

Cities across California must prioritize the implementation of Cr6 treatment solutions while protecting their investment. Therefore, as cities set out to meet today’s 10-ppb MCL, they must consider the MCL of the future and adopt the right Cr6 treatment approach that can cost-effectively comply with a more stringent regulatory limit. SafeGuard™ H2O provides a solution that ensures safety and confidence for cities. With SafeGuard™ H2O, cities can pursue a water blending strategy where appropriate and be assured of sustainable compliance if the State decides to lower the MCL.

Viewpoints: Benefits of Real-time Monitoring of Lead and Copper in Drinking Water Systems

The Lead and Copper Rule Improvements (LCRI) regulation will rely more heavily on using lead and copper testing and monitoring apparatuses. These apparatuses have issues around sampling constraints and lack real-time data on water corrosivity to anticipate the risk of lead/copper corrosion before it happens in homes/schools/daycares. This is where the benefit of real-time lead and copper monitoring in drinking water systems can significantly contribute to a water system’s compliance with the proposed lead and copper action levels outlined in the LCRI. The automatic, unattended online MetalGuard™ analyzer from AMS provides high-frequency, timely, and accurate predictive data to stakeholders on their exposure to lead or copper contamination risks.

Viewpoints: The Urgent Need to Replace the Use of Bulk Ferric Chloride with a More Sustainable Technology

With increasing concerns about the quality of bulk reagents such as bulk ferric chemicals that are widely used in the water treatment industry, utilities are seeking alternative, more carbon neutral, and environmentally friendly treatment methods. AMS’ SafeGuard™ H2O technology is a sustainable alternative that responds to that need. SafeGuard™ H2O has numerous advantages over traditional coagulation processes that depend on bulk ferric chloride. The system’s on-site generation of a ferrous/ferric reagent requires a smaller footprint, and it offers greater reliability to utilities looking to reduce GHG emissions. SafeGuard™ H2O also has a 30 – 50% lifetime cost advantage, considering the cost of purchasing bulk chemicals, manual process supervision, and waste disposal. SafeGuard™ H2O is poised to replace the use of hazardous bulk reagents since it does not compromise the quality of drinking water, harm the environment and it can be produced using renewable energy sources and stored for later use when these are unavailable.

Report: Hexavalent Chromium Treatment and Compliance Study of SafeGuard™ H2O at the City of Banning, CA

A SafeGuard™ H2O demonstration system with a capacity of 3 gpm (150 mL/minute) was installed onsite for testing at the City of Banning’s Facility Well C2 from June-September 2022. The scope of this demonstration focused on the safe, reliable reduction of Cr6 to Cr3 using SafeGuard™ H2O electrogenerated stannous reagent.  The demonstration validated the effectiveness of the 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.

Report: City of Alamosa Evaluates SafeGuard™ H2O Arsenic Removal Technology

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.
