The semiconductor industry has found that traditional analytical methods for complexed copper in wastewater are not fit for purpose since complexed copper cannot be accurately measured using ion-selective electrodes and colorimetry technology, while accurate, has significant challenges. Given these challenges, Samsung Austin Semiconductor (SAS) evaluated the MetalGuard™ analyzer’s performance and ability to significantly improve the safety and quality of measurements for copper wastewater streams.

The MetalGuard™ analyzer provides real-time, multi-stream, reliable, and accurate analysis of trace metal contaminants to ensure compliance with regulatory requirements. MetalGuard monitors contaminants such as As, Cd, Co, Cr, Cu, Fe, Pb, Ni, Se, U, V, and Zn with sensitivity down to 1 ppb and measurement times between thirty minutes and less than two hours. The fully automated online analyzer is offered with an annual service contract inclusive of a 10-year warranty.

Intelligent water treatment systems incorporate real-time sensing to ensure that their performance is optimized to avoid under- or over-treatment and that any deterioration in system performance is signaled to permit timely remedial intervention.

AMS has completed the successful demonstration of their SafeGuard™ H2O proof of concept for the treatment of hexavalent chromium (Cr(VI)) at the City of Los Banos in California. The novel technology generates a stannous ion reagent in-situ via an electrolytic process and also features an online Cr(VI) monitoring analyzer to ensure remediation of Cr(VI) to below 10 ppb.

Aqua Metrology Systems and University of Massachusetts Amherst (UMass Amherst), have partnered to develop a robust online raw-water trihalomethanes (THMs) -precursor analyzer. On 23 January 2018 they received a commitment from Massachusetts Clean Energy Center (MassCEC) through its AmplifyMass program to cost share in the development and assessment of this new online THM-Precursor analyzer.

HollyFrontier Cheyenne Refining LLC, a subsidiary of HollyFrontier Corp., Dallas, has purchased and installed the MetalGuard™ Selenium online analyzer to measure the wastewater selenium profile at the Cheyenne Refinery, Cheyenne, Wyoming.

SafeGuard™ is an automated 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. SafeGuard 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 MetalGuard™ Chromium analyzer provides real-time, reliable, and accurate data on hexavalent chromium [Cr(VI)] and Total Cr contaminant levels in just 30 minutes with sensitivity down to 0.5 ppb. The fully automated online analyzer is offered with an annual service contract inclusive of a 10-year warranty.

The MetalGuard™ Selenium analyzer provides real-time, reliable, and accurate data on selenium levels, including selenite and selenate. Results are available as quick as 30 minutes or in less than two hours, with sensitivity down to 1 ppb for certain selenium species. The fully automated online analyzer is offered with an annual service contract inclusive of a 10-year warranty.

The MetalGuard™ Arsenic analyzer provides real-time, reliable, and accurate data on arsenic levels in just 30 minutes with sensitivity down to 1 ppb. The fully automated online analyzer is offered with an annual service contract inclusive of a
