Case Study: The Brunswick & Topsham Water District Optimizes Operation and Validates Laboratory Results with Online THM Analyzer
The Brunswick & Topsham Water District (BTWD) in Maine was receiving high THM results despite implementation of best practices. The use of the THM-100™ online THM analyzer has proven a valuable tool enabling BTWD to optimize operations, better understand treatment processes, resolve THM compliance concerns and validate laboratory performance and results.
News: Online Cr(VI) Monitor Validates RCOF Process
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 AMS. 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.
Application Brief: Use of Online THM Analyzer Helps Maintain Water Quality at a Scottish Water Drinking Plant
Scottish Water has relied on the reliability and accuracy of the online THM-100™ monitor to monitor real-time THM levels at several of its facilities. The online THM monitors have allowed Scottish Water to consistently monitor, maintain, optimize, and respond to any THM concerns promptly.
News: EU Utility Receives Accreditation for THM-100™
Aigües de Barcelona, the leading water utility in Spain, has received accreditation to the ISO/IEC 17025:2005 Standard for using AMS’ online THM-100™ analyzer to continuously monitor THMs in its drinking water supply network, which serves 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.
Application Brief: Online THM Analyzer Aids THM Mitigation Strategies for City of Santa Cruz
The City of Santa Cruz Water Department (SCWD) has adopted the online THM-100™ THM analyzer for DBP management. Real-time and reliable data on THM and THM Formation Potential levels within the Graham Hill Water Treatment Plant and distribution network have been provided to the SCWD by the online analyzer. The THM-100 online analyzer has aided the SCWD in daily operations and management of feasibility studies to reduce distribution system THM levels.
Application Brief: Online THM Analyzer Proves Valuable for Birmingham Water Works Board
The Shades Mountain Filter Plant operated by the Birmingham Water Works Board (BWWB) has benefited from the real-time high-frequency data on daily trihalomethane (THM) values provided by the online THM analyzer, THM-100™. The online THM analyzer has proven valuable to THM mitigation strategy and optimization.
Application Brief: Central Texas Water Supply Corporation Manages DBP Formation with Help from Online THM Analyzer
The Central Texas Water Supply Corporation has incorporated an online trihalomethane (THM) analyzer, THM-100™, at their WTP to help manage DBP formation. The THM-100 is a viable tool, among others, that enables plant operators to have a firm and immediate understanding of water quality leaving their plant and throughout their distribution network.
Report: Ammonia-Laden Centrate Used for THM Control at Tres Rios WRF
The Pima County Regional Wastewater Reclamation Department is using the THM-100™ to optimize its chlorine injection process at its Tres Rios Water Reclamation Facility where ammonia-laden centrate is used 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.
Viewpoints: Control DBP Formation in Wastewater Effluent with Online THM Analyzer
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.
Report: THM-100™ Yields Excellent Results in WRF Report
In a newly released Water Research Foundation (WRF) report, TTHM concentration results from the THM-100™ analyzer yielded excellent results. Throughout the duration of the demonstration testing, results obtained from the AMS THM-100™ analyzer were within ± 10% of laboratory results. In addition to the TTHM concentrations, the individual THM species concentrations also matched very well between the AMS instrument and the laboratory.
Evaluation of the field TTHM analytical instruments demonstrated that these instruments are easy to install and operate, can generate TTHM results quickly, and most importantly accurate and precise.
