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.

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™ 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 analyzer’s robust and stable design ensures it can maintain its sensitivity and calibrated status for an unlimited timeframe while operating reliably regardless of sample matrix conditions.

MetalGuard™ Arsenic is the first fully automated, online arsenic analyzer for monitoring drinking water arsenic levels. The online analyzer provides high frequency real-time data on arsenic contaminant levels in thirty minutes with sensitivity down to 1 ppb.

The Pima County Regional Wastewater Reclamation Department is using the THM-100™ to optimize its chlorine injection process. The Tres Rios Water Reclamation Facility is using ammonia-laden centrate for THM control. The THM-100 monitor enables the facility to optimize its chlorine injection process and minimize the formation of THMs in its effluent water by providing the operational staff with immediate and accurate daily reports on THM levels.

Balancing THM mitigation strategies with nitrogen and nutrient removal processes is key for staying compliant. In this viewpoints piece, AMS discusses the importance of controlling THMs in wastewater effluent and how online THM analyzers can help wastewater treatment plants stay on top of strict regulatory requirements. The article dives into the various factors — like source water characteristics and disinfection variables — that affect THM formation, while emphasizing the importance of measuring real-time THM levels in wastewater effluent.

Real-time data and analytical information from online instruments help utilities comply with water quality regulations. The complete article detailing how online water quality instruments are poised for growth was published in the March/April 2015 issue of World Water.
