AMS Chief Scientist Michael West, Ph.D., reflects on Earth Day and shares his views on water quality and environmental challenges. 

Medora Corporation (Medora) and Aqua Metrology Systems (AMS) have teamed up to deliver a complete trihalomethane (THM)compliance solution for water utilities to manage harmful disinfection byproducts (DBPs). Medora has announced that it will be using AMS’ online THM and THM Formation Potential analyzer, THM-100™, to provide real-time and predictive analytics data to design and operate its aeration system more efficiently, thereby saving utilities high treatment costs while ensuring compliance with regulatory standards.

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.

The semiconductor industry has found that traditional analytical methods for complexed copper in wastewater are not fit for purpose. Complexed copper cannot be measured using ion-selective electrodes and colorimetry technology faces a number of severe challenges. Faced with the challenges of colorimetry, Samsung Austin Semiconductors (SAS) evaluated the MetalGuard™ analyzer for its potential to significantly improve safety and quality of measurements for copper wastewater streams.

Innovative SafeGuard™ H2O intelligent Cr(VI) treatment system has been successfully demonstrated at the City of Los Banos in California. This 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. The technology provides an economical and reliable treatment for water systems affected by contamination from Cr(VI), a known carcinogen.

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.

AMS appoints Felipe Carvalho as CFO to propel the company’s ambitious growth plans in the United States and abroad. Felipe will lead the company’s fund raising activities aimed at accelerating the growth of the company. Felipe will also play an active role in developing AMS’s international presence.

A California Water Utility experiencing elevated levels of hexavalent chromium [Cr(VI)] in their drinking water supply is the first commercial application to use the MetalGuard™ Cr(VI) real-time water quality monitor developed by Aqua Metrology Systems. The monitor was installed to provide high frequency, reliable, and accurate data on hexavalent and total chromium levels during the pilot test of a Reduction/Coagulation/Oxidation/Filtration (RCOF) process.

Aigües de Barcelona, the leading water utility in Spain, has received accreditation to the ISO/IEC 17025:2005 Standard for the use of Aqua Metrology Systems’ online THM-100™ analyzer to continuously monitor trihalomethanes (THMs) in their dinking water supply network servicing 3,000,000 million inhabitants across metropolitan Barcelona.  In addition to providing the utility with contract compliance and process optimization data, THM readings can now be used to submit regulatory compliance data.

Lowell Institute for Mineral Resources in conjunction with Sub Rosa Monitoring LLC has developed a fully automated and self-calibrating water quality monitoring system to measure surface and subsurface fluid flow and ground water quality for a copper mine in Arizona. After evaluating a variety of trace metals analytical approaches for integration into the broader water quality monitoring system, the University of Arizona selected the SafeGuard™ Duo online/offline analyzer from Aqua Metrology Systems due to its automation and precision.
