TRUMPF, a manufacturer of laser diodes made from Gallium Arsenide substrates (GaAs) wafers, implemented a new wafer thinning process in 2019. With large volumes of process wastewater and high treatment costs, TRUMPF needed a practical, cost-effective wafer-thinning wastewater treatment process that would also allow them to meet local regulatory discharge requirements. TRUMPF undertook a treatment approach that included the installation of the MetalGuard™ Arsenic online arsenic analyzer to continuously measure influent and effluent arsenic levels in real-time, providing TRUMPF with accurate and reliable results in less than 30 minutes to measure the performance of its IEX system and ensure regulatory compliance. The wastewater treatment approach undertaken by TRUMPF resulted in process improvements, providing an estimated annual cost savings of more than $150K with an ROI of less than one year.

California American Water turned to AMS’s MetalGuard™ fully-automated, online multi-stream Cr(VI) analyzer to have higher visibility of Cr(VI) contaminant levels in real-time and allow them to better monitor and address critical steps in their remediation process. 

Online instruments help water utilities control water treatment operations. CEO Rick Bacon of Aqua Metrology Systems explains how utilities rely on sensors to meet water quality compliance standards and optimize operational performance in the May/June 2019 issue of World Water.

As regulatory requirements and the availability of more accurate diagnostic technologies continue to push the legal threshold limit of contaminants, utilities are turning to high-frequency data to identify contaminant threats and diagnose critical treatment system performance. Learn how El Paso Water’s Upper Valley Water Treatment Plant met regulatory requirements with the help of AMS’s MetalGuard™ automated, online arsenic analyzer.

The rapid response benchtop THM-RR™ analyzer provides fast, reliable and accurate analysis of individual and total THM concentrations. For water treatment operators, consulting engineers and THM treatment system vendors the THM-RR delivers valuable THM performance data far faster than external laboratories.

Aqua Metrology Systems has partnered with Foundation Instruments, Inc. to expand its offerings of online and real-time monitoring of trihalomethanes (THMs) with the addition of Foundation Instruments’ THM-Rapid Response (THM-RR) online benchtop analyzer. The benchtop analyzer reports individual and total THM concentrations in real‐time so that utilities can be more proactive in responding to water quality changes and managing carcinogenic disinfection by-products (DBP).

2018 was a busy year for AMS. We raised awareness about the value of real-time, online high-density data to determine the presence of water-borne contaminants and began deployment of our own patented Intelligent Water Treatment System for chromium, mercury, lead and selenium remediation. In 2019, we anticipate wider adoption of our online contaminant analyzers in North America and Europe and plan to broaden access to safe drinking water through innovative drinking and wastewater treatment technologies.

AMS announced the demonstration of its SafeGuard™ H2O Hexavalent Chromium [Cr (VI)] remediation system at California’s Hidden Valley Lake Community Services District. Real-time data on the system’s performance will be streamed live, providing transparency of the pilot study and treatment efficacy of the technology.

AMS has recently completed the successful demonstration of a proof of concept for the removal of dissolved mercury (Hg²⁺) in power plant wastewater. The SafeGuard™ H2O system offers a low-cost, reliable remediation system proven to address a range of trace metal contaminants, including ionic mercury.

The innovative SafeGuard™ H2O intelligent Hg(II) remediation system has been successfully demonstrated in a bench test study to remove ionic mercury in power plant wastewater. This novel technology generates a stannous ion reagent in-situ via an electrolytic process, providing a cost-effective alternative to highly challenging and expensive existing mercury treatment process.
