Advanced Lead Corrosion Control and Risk Management

Communities across the world are plagued by lead contamination and corrosion concerns, which often come to light during testing of children’s blood and after the event has occurred. AMS has developed advanced solutions for lead corrosion risk management and control. AMS’ online lead corrosion monitoring technologies are backed by actionable, high-frequency data, providing a comprehensive risk map that informs public health authorities, water treatment plant operators and consumers. AMS’ intelligent in-situ corrosion inhibitor generation and delivery technology offers a localized treatment solution that displaces orthophosphates and provides a responsive, point-of-care, effective approach to manage the multi-variant challenge of lead corrosion risk.

AMS Delivers an Affordable Treatment Solution for Hexavalent Chromium Removal in California

Hexavalent chromium (Cr6) in drinking water is a controversial topic in California. More than 20 years after the film Erin Brockovich was released raising public awareness and concern about Cr6, high levels of the contaminant continue to pose a threat to the health of thousands of consumers. To meet the need for an affordable treatment system that eliminates Cr6 from drinking water supplies and removes the barrier to a lower regulatory limit for this carcinogen, AMS developed SafeGuard™ H2O. The technology ensures a safe and affordable treatment approach to meet the Cr6 public health goal of 0.02 ppb while saving California taxpayers millions of dollars. During a pilot demonstration at the City of Los Banos, Calif., AMS’ SafeGuard H2O Cr6 treatment system proved to reduce Cr6 to non-detect levels at an annual cost per household in small communities of less than $5 per day.

Technology Overview- Effective Management of Corrosion and Biofilm in Cooling and Heating Systems with SafeGuard™ H2O

Many industries, hospitals, institutions, and buildings are faced with the inevitable task of managing corrosion and biofilm in their cooling and heating systems. With the SafeGuard™ H2O intelligent corrosion management system these facilities can extend their useful life, reduce maintenance expenditures and foster sustainability. SafeGuard H2O is an innovative electrochemical water treatment solution developed by AMS. A non-toxic and environmentally safe stannous reagent is generated on-site using only tin and electricity and is delivered in a tightly controlled dose. This all-in-one reagent acts as both a biocide and a corrosion inhibitor. The fully integrated and online SafeGuard H2O treatment approach eliminates the pitfalls of conventional corrosion and biofilm management systems and aids in the delivery of an affordable and reliable process.

Technology Overview- SafeGuard™ H2O In-Situ Stannous and Tin Dioxide Generator

SafeGuard™ H2O is a fully automated, on-demand, in-situ generator of stannous (reducing agent) and tin dioxide (adsorbent), coupled with online monitoring capability developed by AMS to address waterborne and airborne contaminants. The system removes Cr(VI), Cu, and Pb from drinking water and Cr(VI), Hg and Se from wastewater; acts as corrosion inhibitor for lead pipes and cooling systems; adsorbs H2S, NOx, SO2 from industrial emissions. The fully integrated and online SafeGuard H2O treatment approach eliminates the pitfalls of conventional systems and aids in the delivery of an affordable and reliable remediation process. SafeGuard H2O is integrated with an online contaminant monitoring capability. There are no similar technologies to SafeGuard H2O that integrate a low life-time cost contaminant treatment system with real-time performance controls.

Los Banos, Calif. SafeGuard™ H2O Cr(VI) Treatment System Pilot Report

A SafeGuard™ H2O intelligent Cr(VI) remediation system demonstration unit with a treatment capacity of 10 gpm was installed with the City of Los Banos, California to evaluate the performance of the technology to treat Cr(VI) to non-detect levels (under 1 ppb) in unchlorinated well water.  SafeGuard H2O is an innovative technology based on a proprietary approach that generates on demand a stannous ion reagent in-situ via an electrolytic process. The pilot with Los Banos provided confirmation of the technology’s efficacy and third-party validation of the SafeGuard H2O system as a cost-effective alternative to traditional Cr(VI) treatment systems. Results are detailed.

Minimize the Environmental Impact of Semiconductor Manufacturing with Real-Time Online Trace Metals Analysis

Semiconductor manufacturing is not only highly dependent on large volumes of water that must be treated to ultrapure standards, but the process also generates significant volumes of wastewater that contains heavy metals and toxic solvents. To reduce its environmental impact, the semiconductor industry is actively searching for new ways to optimize water consumption and improve the quality of wastewater effluent. AMS offers innovative online real-time, continuous trace metals monitoring solutions designed to aid the semiconductor industry in optimizing water consumption, improving the quality of wastewater effluent and reducing its environmental impact.

AMS Advances the Evaluation and Review of a More Stringent Federal Arsenic Standard with Its SafeGuard™ H2O Innovative and Cost-Effective Arsenic Removal Technology

It has been nearly 20 years since the U.S. Environmental Protection Agency (EPA) federal arsenic standard of 10 parts per billion (ppb) was put into place; however, the 2001 regulation remains the same today with the exception of New Hampshire and New Jersey that have implemented a more stringent maximum contaminant level (MCL) of 5 ppb at the state level (EPA, 2001). This paper aims to advance the evaluation and review of a more stringent federal arsenic standard by presenting evidence of an innovation in arsenic removal technology — Aqua Metrology Systems’ (AMS) SafeGuard™ H2O (SGH2O) — that is proven, validated and commercially available. The technology virtually eliminates arsenic and drastically reduces the cost of removing the toxic contaminant from water supplies when compared to alternative treatment technologies.
